Why Rotax Is Your Leading Copper Sheet Supplier
Copper was first utilized 10,000 years ago. Itsdiscovery marked the end of Stone Age and the beginning of the Metal Ages. Despite being the first metal discovered by man, its popularity was easily dwarfed by that of gold and silver, which were rarer and considered more valuable. Then again, copper remained the most extensively used metal due to its many amazing properties.
Properties of Copper
There are many metals that exhibit great properties but copper stands out, and it’s not difficult to understand why. Here are some of the properties that make copper one of the most useful materials around:
- Electrical Conductivity. Copper is the second most electrically conductive metal, next to silver. Most of the wires and cables you see at home, along the tree lines outside, or within vehicles and machines have copper cores.
- Thermal Conductivity. The main reason why copper, not silver, is used as core of electrical wires is that it has a higher thermal conductivity than silver. Silver wires have been banned from commercial use because they easily burn when conducting high voltage of electricity.
- Corrosion Resistance. Copper is a non-ferrous metal, which means it doesn’t contain iron, a metal that forms rust when exposed to oxygen. It only forms patina on its surface overtime but this type of blemish is only on the surface and does not spread within the metal. In fact, it serves as a protective layer for copper.
- Ductility. Another reason why copper is an ideal material for making wire cores is that it is highly ductile. This means it can be drawn or pulled into a small string without breaking.
- EaseofAlloying. Unlike most metals, copper is very easy to alloy with other metals. In fact, its main alloys—bronze and brass—have dozens of types, each of which contains a different additional element.
- Antimicrobial. Copper is also known for its ability to produce the oligodynamic effect, which can kill various types of microorganisms. It’s no wonder this metal, along with its alloys, is a great choice for cookware, plumbing, and other applications that require sanitation.
- Recyclability. Not very many types of metal can be recycled. Copper is only one of the few, since it does not corrode or rust. This makes it an eco-friendly choice of material for all kinds of project.
Because of the unusual physical and chemical characteristics of copper alloys, they are produced only in a set of shapes specific to that particular alloy. Most projects require more than one because of the difference in alloys –one for tubing, one for sheet, and so on. There are 40 copper alloys regularly available in the US.
Alloys of Copper
The most popular alloys of copper are bronze (copper-tin) and brass (copper-zinc). After all, they were discovered several thousand years prior to the copper alloys of today. In fact, bronze had become even more popular than copper itself for some time, so much so that an entire era was named after it. At present, there are over a hundred different types of copper alloy. Here are some of the most prominent of them:
- Muntz Metal. Thiscopper alloy is commonly used in shipping and in the manufacturing of bolts. People found other uses for Muntz metal considering that it’s lightweight and extremely durable. Historically, Muntz metals were used in all things shipping, from lining the lower parts of pier pilings to the hulls of ships and then later to manufacturing bolts. Muntz has truly found its place among the metal alloy giants in the manufacturing world thanks to its ability to stand up against some of the most corrosive environments.
- Leaded Brass. While brass is already among the most workable types of metal, there are applications in which higher machinability is required. To increase brass’s machinability, lead is added into the mixture. Lead serves as a microscopic chip breaker and tool lubricant, allowing the molecules and lattices of brass to slide against each other more smoothly. Whether you need a special type of brass channel or simply a brass that can be formed into extremely thin sheets, adding lead can definitely help.
- Naval Brass. This alpha-beta brass consists of copper, zinc, tin, and a trace amount of lead. Such combination produces a metal that resists saltwater corrosion. This is why naval brass is often used for seawater service applications, hence the name.
- Architectural Bronze. As the name suggests, architectural bronze is often used for home design and building applications, including window and door frames, furniture edges and trims, and railing. Architectural bronze bars and sheets are extremely durable yet easily patinated.
- Commercial Bronze. Some bronzes contain zinc apart from tin, making them tougher against various kinds of pressure. The zinc in commercial bronze is perfectly combined that commercial brass us completely resistant to dezincification. It is also resistant to stress-corrosion cracking, making it a suitable material for electrical water bars and weather strips.
