Brass is a copper alloy with zinc as the main added element. It has a beautiful yellow color and is collectively called brass. Copper-zinc binary alloy is called ordinary brass or simple brass. Brass with more than three elements is called special brass or complex brass. Brass alloys containing less than 100% zinc are composed of solid solutions and have good cold working properties. For example, brass containing zinc is often used to make cartridge cases, commonly known as cartridge case brass or 73 brass. Brass alloys containing zinc between In order to improve the performance of ordinary brass, other elements are often added, such as aluminum, nickel, manganese, tin, silicon, lead, etc. Aluminum can improve the strength, hardness and corrosion resistance of brass, but reduces the plasticity. It is suitable for use as condensation tubes and other corrosion-resistant parts for sea vessels. Tin can improve the strength of brass and its corrosion resistance to seawater, so it is called naval brass and is used for ship thermal equipment and propellers. Adding tin to brass can significantly improve the heat resistance of the alloy, especially its ability to resist seawater corrosion. Therefore, tin brass is called navy brass. Tin can dissolve into copper-based solid solution and play a solid solution strengthening role. However, as the tin content increases, brittle r-phase compounds will appear in the alloy, which is not conducive to the plastic deformation of the alloy. Therefore, the tin content of tin brass is generally in the range of ~. Commonly used tin brass include,,, etc. The former is an alloy with high plasticity and can be processed by hot and cold pressure. The latter two grades of alloys have a +b two-phase structure, and often have a small amount of r phase. They have low room temperature plasticity and can only be deformed in a hot state.
