The brief introduction to Brass plates

Brass plate is a widely used lead brass with good mechanical properties and good machinability. It can withstand hot and cold pressure processing. It is used for various structural parts such as gaskets, linings sets etc. Tin brass plate has high corrosion resistance, good mechanical properties, good pressure workability in cold and hot states, and can be used for corrosion-resistant parts on ships, parts and conduits in contact with steam, oil and other media. Brass is an alloy of copper and zinc. The simplest brass is a copper-zinc binary alloy called simple brass or plain brass. Brass with different mechanical properties can be obtained by changing the zinc content in brass. The higher the zinc content in brass, the higher the strength and the lower the plasticity. The zinc content of brass used in the industry does not exceed 45%. No matter how high the zinc content is, it will cause brittleness and deteriorate the alloy properties. In order to improve certain properties of brass, the brass that adds other alloying elements on the basis of one-dimensional brass is called special brass. Commonly used alloying elements are silicon, aluminum, tin, lead, manganese, iron and nickel. Adding aluminum to brass can improve the yield strength and corrosion resistance of brass, and slightly reduce the plasticity. Brass containing less than 4% aluminum has good comprehensive properties such as processing and casting. Adding 1% tin to brass can significantly improve the resistance of brass to seawater and marine atmospheric corrosion, so it is called "navy brass". Tin also improves the machinability of brass. The main purpose of adding lead to brass is to improve machinability and wear resistance, and lead has little effect on the strength of brass. Manganese brass has good mechanical properties, thermal stability and corrosion resistance; adding aluminum to manganese brass can also improve its performance and obtain castings with a smooth surface. Brass can be divided into two categories: casting and press-worked products.
