Why Get Your Materials from Brass Extrusions Suppliers

brass extrusions


Some metal-based structural or mechanical designs are so elaborate that forming parts of accurate shapes and cuts can be practically impossible. Of course, they can be cast or smelted but there’s a limit to how precise casting or smelting output can be due to metal’s sensitivity to temperature change. Fortunately, there’s another metalworking technique that works better than casting in so many ways—extrusion. It involves pressing metal, either hot- or cold-worked, into a series of dies to achieve a desired shape. Here are some of the benefits of extrusion you won’t enjoy from other metalworking techniques.


High Production Volume

Meeting deadlines has always been a tough ordeal for any production work. Metal manufacturers that have high demand yet are always battling with tight production schedule would do well to consider extrusion instead of casting. Apart from having a fewer number of steps, the process also guarantees fast cooling and curing, which is essential to fast-paced delivery. Even if the metal has to be hot-worked, the temperature isn’t too much to require time extension for cooling and compensating for expansion.

Low Cost per Unit

Because extrusion allows for mass production of items, be it a long tube or small machine parts, within a short period, production cost is also much smaller, making the entire process cheaper. It requires less amount of fuel than casting, too, so that further lowers the overall production cost. It’s no wonder many manufacturers and suppliers prefer extrusion from the country’s top bronze or brass extrusions suppliers because with it they can save a lot of money in the long run.

High Quality

When a billet is fed into the die, it takes on high compression, which causes its molecules to contract even further. This contraction increases the density of the metal, making it much stronger, tougher, and indestructible. When compared to cast metals, extrusions exhibit far better performance and durability. So if you want an item for your vehicle or machine to be of superior quality, choose an extrusion.

Excellent Finish

When it comes to surface finish, extrusion goes beyond what can be expected of cast metal—dense, smooth, and almost always free of voids that make metals weak or brittle. This is why many suppliers prefer extrusion for projects that necessitate excellent, uniform surface finish. It’s the unique, practical process that makes this possible. When the billet enters the die, its sides slither against the sides of the die, causing a polishing effect that results in a gleaming and seemingly buffed exterior, which unsurprisingly you won’t find in a freshly cast metal.

With all of these benefits, you can definitely tell that extrusions are so much better than cast metals and those produced from other metalworking techniques. When poorly done, however, extrusion may actually result in the opposite—flawed surface and full of voids. Insufficient or too much pressure applied could cause the billet to either deform or even crack. This is why you need to be careful when choosing a supplier. Make sure that they have mastered the craft of extrusion through many years of experience, have a superb track record, and supplies for many large projects and companies in North America. If you need bronze or brass extrusions for your own project, companies like Rotax Metals that have been around for almost a century are your best option. Not only do they have their owned fully furnished foundry, but they also get their raw materials from the most trusted suppliers.



Why Your Neighborhood Brass Extrusion Suppliers Never Run Out of Order

brass extrusion suppliers Extrusion is a metalworking technique that involves pushing a material through a die to create objects of fixed cross-sectional profiles. Manufacturers often prefer this technique traditional casting because of its ability to create complex cross-sections. Since the whole process relies on compression and shear forces, it is perfect for working brittle metals as well. Generally, all malleable and ductile metals can be extruded. Their unique properties enable them to conveniently flow through the die even with minimal compression. It can therefore be presumed that the most ideal metals to work using this technique are those with naturally high malleability, such as copper alloys.

Of course there’s the option to alter the density of the workpiece before being fed into the extrusion machine, simply by regulating its temperature. Heat excites the molecular composition of the workpiece, consequently increasing its fluidity. Some manufacturers, however, veer away from this option because chemical change through heating may have irreversible effect on the work piece’s original properties, resulting in poor-quality output.

Among the copper-based workpieces manufacturers use, brass is arguably the easiest to extrude. Manufacturers choose this metal over most other copper alloys is that it can be easily extruded even at room temperature.

Brass Extrusions

All alloys that consist of copper and zinc are classified as brass. High-quality brasses usually have around 70 percent copper and 30 percent zinc. Sometimes, other elements, such as arsenic, lead, phosphorus, aluminum, manganese, and silicon are added to the mixture to produce variants that suit more specific applications.

Brass is one of the most workable metals available, which is probably why it is a preferred material for extrusion. On another note, most of the products that require extrusion due to their intricate design are best made of brass. Simply put, while extrusion is not exclusive for brass, it clearly works well than other metalworking techniques when brass is the base metal.


Brass has some properties that are not found in any other metal. One of these is its excellent reaction to friction. When rubbed against other metals, brass does not easily produce heat or spark, making it the perfect material for application where low friction is necessary, including locks, gears, bearings, doorknobs, ammunition casings, and valves. For the same reason, it is also an ideal material for making select components of plumbing and electrical systems where immense pressure is often involved.

Brass extrusions are in high demand in various industries, particularly in architecture and construction. Because of this, brass extrusions suppliers never run out of orders regardless of the season and market condition. Apart from doorknobs and locks, brass can also be extruded to make handrails, columns, skirting, and cornices. Some furniture with intricate cross-sectional features can be made from brass extrusions as well.

Other Benefits of Extrusion

Although extrusions are usually appreciated for the natural properties that their base material possesses, some of those appreciable features may not be achievable with metalworking techniques other than extrusion. Unlike cast, forged, or drawn metals, extrusions have the following characteristics:

  • Corrosion resistance the surpasses that of regular cast metals
  • High strength due to increased density through compression
  • Better hot or cold workability than cast metals
  • Lasting sheen and improved machinability
  • Suitability for intricate shapes and configurations
  • High electrical conductivity

Extrusion also proves more efficient than casting in terms of production, considering that its process consists of fewer steps. This is why most manufacturers choose this technique for mass production, although they prefer casting for custom work.

If you are interested in using brass extrusions for your project, make sure that you will get your materials from a certified copper product supplier, such as Rotax Metals. Don’t hesitate to ask them “what’s the price of brass” in case you are not familiar with the different grades available in their store.
