Some Facts about Metals Before Buying from Aluminium Bronze Suppliers

Metals in interior design never go out of style. They remain high in demand because they are simple to incorporate in any design element, and can effectively elevate the aesthetic of a room almost immediately.

As easy as it is to do right, however, it can also be just as easy to get it wrong. Professionals make sure to carefully take note of the desired theme to avoid adding in items that could clash with it. A rustic-themed interior, for example, would predominantly have wood materials. Metals can be incorporated too, but certainly not by a lot, and depends on the kind that will be used. Bronze is a good option, to go with the wood aesthetic, for example, because it does “age” beautifully with its patina.

Before you go looking where to buy bronze metal, here are some helpful information on bronze metal and how you can work them into your designs for a simple yet sophisticated look.

Composition and Properties

Technically speaking, bronze is a type of alloy resulting from a combination of copper and another type of metal. The most common pairing is usually copper and tin, although there are many possible varieties.  Other elements contained in bronze may include aluminum, arsenic, manganese, nickel, silicon, or zinc.

Bronze takes on a golden appearance, which is why it is a good substitute for gold. It is also hard but malleable, thus making it a good option for metal art, among its many other functionalities. In particular, bronze is a great choice for sculpture casting because it expands by just a small amount when its form solidifies from a liquid state. This helps better fill the mold, allowing the casting mold to be filled precisely.

Apart from that, it also does not generate sparks when used to strike against a hard surface. It also has considerably low friction, especially when compared against other metals. This makes it a good alternative to steel, especially when working with or around flammable materials.

Unique Patina

The trademark characteristic of bronze is the patina or discoloration. This is actually a result of exposure to air. The oxidation only affects the outermost layer of the bronze metal, though, which means that the rest of the material remains in its original state.

The patina starts out as copper oxide, and then later on transforms into carbonate.  The oxidation process itself is no threat to the metal, and in fact even protects the inner layers against corrosion. What you should be careful about when using bronze are the chlorides, such as those in sea water. This can lead to the formation of copper chlorides, which in turn can give rise to corrosion that can destroy the metal. This occurrence is otherwise known as the “bronze disease.”

Care & Maintenance

If you prefer to have the bronze metal pristine and without patina, clean it regularly with the following steps. Simply use warm, distilled water to rinse the metal, and then put on paste made of baking soda and lemon juice. Gently clean with a brush; ideally, you should use the one with soft bristles so that it doesn’t scratch the surface of the bronze material. An alternative mixture for the paste could also be flour and salt mixed with white vinegar. Once you’ve scrubbed the metal with the paste, leave it on for 20 minutes before rinsing.

If the material has already developed the bronze disease, you will have to clean it a lot more frequently. You will need to soak it in a sodium sesquicarbonate solution (5% or less), changed every week. Again, always remember to use only warm, distilled water for rinsing. You’ll know the treatment has worked once the pH level turns neutral.

One thing you have to keep in mind when maintaining bronze is that oxidation is a naturally occurring process for the material when it is exposed to air. Therefore, unless you intend to keep it locked up in a glass case, you can be certain that it will develop patina again after cleaning. The other thing you can do to protect the material is to coat it in entirely with lacquer. Make sure not to miss a spot.

Types of Bronze Alloys

As was mentioned earlier, there are different types of bronze metals, depending on what combination is used. While each type would have their own special attributes, what remains constant across the board is the strength and durability, which is why it’s considered to be one of the most reliable metals around.

Aluminum Bronze – This is said to be the strongest among all types of bronze. It also scores major points for being corrosive-resistant. It has a more industrial functionality too, precisely because of these features. It’s most commonly used in marine hardware as well as in pumps that carry corrosive materials.

Copper Nickel – Like aluminum bronze, copper nickel is also strong and corrosive-resistant. What makes it stand out, however, is its strong thermal stability. This makes it ideal for the manufacturing of ship hulls, other marine equipment, electronic components, and the likes.

Nickel Brass – This type of bronze takes on a more silvery color because of the nickel, although the copper content does retain the trademark bronze strength and resistance to corrosion. Common uses of nickel brass include food and beverage equipment, optical equipment, and musical instruments.

Phosphor Bronze – Otherwise known as tin bronze, phosphor bronze is known for being highly durable and fatigue-resistant. It also has coefficient of friction. Because of its features resulting from its composition, this type of bronze is most commonly used in the manufacturing of electronic components, washers, and others.

Silicon Bronze – Comprised of copper and silicon, this type of metal otherwise known as “red silicon bronze” actually only has as much as 6% silicon. Zinc actually comprises 20% while the rest is copper. Pumps and valve parts are the usual products to come out of this particular metal type.

Bronze in Design

Knowing the different types of bronze is crucial in determining what to incorporate in your designs. Especially if you would like to make something more custom, choosing the right materials would be very helpful for your cause.

Establishing a design theme or aesthetic is a good way to start. Identify how big a component is bronze going to be in the overall look of your design. This way, you can plan early on which likely places you can incorporate it to. More importantly, you can easily get in touch with aluminium bronze suppliers and the likes so you can order the things you need immediately.

Having a well-stocked supply should help you move along with your project a lot faster and smoothly. Of course, that goes without saying that you should be mindful of your inventory so that you don’t end up wasting your resources.

Overall, having bronze elements in your design can work wonders in elevating an otherwise simple look into something a lot more elegant and stylish. Bronze frames, for example, can make pictures or paintings stand out even more. Little bronze trinkets and other crafts can help upgrade a simple wooden table. Bronze trimmings and linings can give that subtle shine to handrails, banisters, and interior sidings.

Of course, light fixtures, coat racks, even tables and chairs, cabinets and other decorative elements all could use a pop of bronze too to upgrade its looks. Incorporating these style elements would require a special kind of care, however, that’s why knowing how to care for and maintain these metals is equally important.

Metal suppliers such as Rotax Metals can help you find the right material that you need. With quality materials, you can better execute your design plans.

Among today’s countless types of commercially available metal, only a handful stand out due to their distinct, valuable properties. One that has stood the test of time and has been utilized for a vast array of applications for many generations is bronze. This metal has been around for over 9000 years, making it the first manmade alloy.

What Most People Know So Far

If you paid attention to your history teacher, chances are you already know a thing or two about bronze. You probably know the role it played in the world’s transition from the Stone Age to the Metal Age, and how it helped revolutionize metallurgy, technology, and even war. A great deal of artifacts made of bronze have been unearthed from ruins around the world, proving how valued this metal was in the ancient time.

Bronze became so popular that it was named after an entire era. As to why it became so popular, there are a couple of plausible reasons. First, the Metal Age was just at its early stage when bronze was discovered and the ancient people knew only of a few metals—gold, silver, copper, tin, iron, and lead—most of which didn’t have many utilitarian uses.

Second, of the first few metals available at the time, tin had the highest metallic bonding property, and it bound perfectly with copper but not with the rest of the available metals, which is why bronze was the only alloy they could produce. It would take a few more centuries before man could accidentally discover zinc-rich copper, which would later be polished into brass.

Over the years of working with bronze, metallurgists have not just perfected its composition and succeeded eliminating all its impurities but also created many variants with unique and useful properties of their own. Then again, all of today’s bronzes share certain distinctive traits, such as ductility, low-friction quality, and high machinability.

What Most People Should Know 

There’s no denying the expediency of bronze for many industrial and commercial applications. If you need a material that exhibits high weldability, ease of brazing and soldering, and low thermal expansion coefficient, then bronze bars for sale and other bronze-based supplies are your best option.

However, it is also imperative to know bronze’s limitations so that you can make the most of its potentials. Here are some of the things you should anticipate and prepare for when using any bronze material.

  • Naturally Durable but Needs Extra Care to Last Even Longer

As previously mentioned, bronze is an extremely durable material. With the right combination of copper and tin, along with additional elements if any, and proper upkeep, you can produce a type of bronze that can last for thousands of years. Conversely, bronze is not an invincible material. Like most other metals, it has its own kryptonite. When you are working with bronze, make sure to keep any products containing ammonia and ferric compounds, sulfur, chlorine, and cyanides at bay as these substances can corrode the metal very quickly. The acids in bird droppings have similar effect as well so make sure to keep raw bronze in a covered place.

  • Unremoved Core May Migrate to the Surface

Bronze casting usually involves a mold with a core made of gypsum. Depending on the desired finished product, the gypsum core may be left inside the bronze. Overtime, the gypsum may start to migrate towards the surface, weakening bronze in the process. As much as possible, when you are casting bronze, remove as many foreign materials from the interior and exterior surface of the finished product as possible. Other techniques on how to make bronze may not involve the use of gypsum so this won’t be a problem.

  • It Gets Ill, Too

Non-living things don’t normally get sick. It turns out, such rule does not apply to certain materials, particularly bronze. When placed in an environment where chlorine and oxygen are present, this metal may develop a condition, called Bronze Disease. This disease is caused by the hydrochloric acid that forms when oxygen and chlorine combine in a moist setting. Therefore, it is crucial to avoid using chlorine when bleaching bronze items.

  • Why It Makes a Perfect Sculpture Material

Builders don’t recommend bronze for structural applications, and for one good reason—it is softer than steel and other more common metals. While softness is usually viewed as a weakness when it comes to metals, there are ways to put it to good use. Bronze’s softness allows it to be chiseled and cut with ease, which is why it is the perfect metal for sculpture.

  • You May Need to Spend a Little More

Bronze is not as common as it is popular, and the materials used to manufacture it don’t come cheap. Specifically, its copper content is what makes it expensive. Containing around 95 percent copper, bronze is almost as expensive as copper itself. If you are looking to use bronze for your projects, you will have to fork out a little bit more to afford it.

Knowing these facts about copper can help you make an informed buying decision. More importantly, you’ll realize that you need advice from a metal expert to obtain the specific type of bronze material you need for your project. You can find one in a reputable metal supplier like Rotax Metals. It pays to invest in high-quality products, and so you better purchase from the right supplier.

Fascinating Facts about Bronze and Brass Extrusions and Other Types of Tubing

Types of Tubing

Tubes are among the most useful metal supplies on the market. They are used for a vast array of applications and benefit many different industries, including creative, construction, industrial, and manufacturing. In fact, in any manmade structure, you’ll see a tube or two installed to perform an integral role in the structure’s stability and functionality.

Tubes are not to be confused with pipes. Although they normally look the same, they are different types of material altogether. Generally, pipes are often used for conveying fluids and gases, whereas tubes are used for decorative and structural purposes. The ones inside your walls or underneath the sink are classified as pipes, while your curtain rods and stair railing are considered tubes. There are cases, though, when a tube also functions as a pipe and vice versa, but this is the general idea.

Applications of Tubes

As previously mentioned, tubes can be used for a range of applications. These may include precision tubes in vehicles, stands for tents, and frames for bed bases. Most machines and appliances have handles and other major components made of tube, too. The handles on your shovel and mop as well as the antenna on your old radio are all tubes. To give you a better idea of how vast tube applications are, here are some major uses of tubes that you rarely hear of but are actually very common.

  • Structural. You probably think of tubes as only suitable for small-scale applications, mostly for aesthetic purposes. In truth, tubes also have structural uses. Most of today’s buildings consist of tubular columns and beams. Builders prefer it to other materials because they are flexible and easy to install.
  • Mechanical. When you’re riding a bicycle and suddenly you need to stop and carry your bike down a stairway, did you notice how light it is? If the body of your bike is made of solid steel, you would have difficulty lifting it, let alone carry it down the stairs. Most bicycles have a body made of tubes, which explains why they are very light. The same goes for other types of vehicle.
  • Hydraulic. Any hydraulic system that handles large volumes of fluid at a quick rate to meet increasing levels of demand needs to have an accumulator to cope with extremes. This accumulator, together with a number of components of the hydraulic system itself, is made of tubes.
  • Extinguishing and Distribution. Many tubes are also used for making fire extinguishers, plumbing fixtures, and natural gas distribution systems. These tubes are usually made from the highest quality metals to ensure that they can tolerate extreme pressure and temperature.


Shapes and Materials

Tubes come in different shapes, sizes, and materials to serve different purposes. Those with circular cross-sections are the most common because they are suitable for virtually all kinds of applications. Some tubes have special shapes typically for decorative uses. Rectangular and triangular cross-sections are not preferred for structural applications because their shape may affect the distribution of load and pose a threat to the stability of the structure.

Most tubes with irregular cross-sections are used as standalone or as components of a decorative element. They can be manufactured through casting and rolling or through extrusion. Many manufacturers prefer the latter because it’s more efficient. Extrusion involves pressing a workpiece into a die with the desired cross-section, whereas in casting, the metal has to go through more than a few complex processes before the output is produced.

Two of the metals tube manufacturers commonly use are bronze and brass. Both alloys of copper, they exhibit qualities that are suitable for most applications of tubes. They are malleable as well as durable, and so they can last long and endure high pressures. If you need a brass or bronze tube to replace a missing fixture in your home, find one from a top metal supplier, such as Rotax Metals. Whether you need cast tubes or brass extrusions, they surely have it in their inventory.
