Brass rod is very important, a widely used complex brass, it has excellent cutting performance, wear resistance and high strength, mainly used in mechanical engineering of various connectors, valves, valve stem bearing maintenance, among which hot forging valve blank, lock industry, watch industry is the three important markets, low cost brass is an important premise for its wide application. Its alloy composition can contain a variety of alloy elements, and the content requirement is relatively loose, and laid the foundation for the comprehensive utilization of copper alloy raw materials. Brass is a complex brass with lead as the main additive element. It is a combination of Cu, Pb, Al and Zn4 non-ferrous metals in a ratio. Lead is rarely solidly soluble in copper zinc alloy, and exists as an independent phase in the alloy. Free particles are distributed in the grain boundaries and crystals, which not only lubricates the metal, but also makes the chip into a crumbly shape, which can improve the cutting property and wear resistance of brass. The machinability of brass is proportional to the lead content, but when the lead content exceeds 3%, the machinability of copper is no longer significantly improved, and the hardness, strength and elongation of brass are reduced. Therefore, the main properties of brass can be summarized as wear resistance, corrosion resistance, good toughness.

Brass bar has outstanding characteristics, a wide range of product applications and diverse application scenarios. This article will introduce you here.
