Description:
Lead brass is a complex brass with lead as the main added element, which is a combination of Cu, Pb, Al and Zn 4 non-ferrous metals in a certain ratio. Lead is rarely solid solution in copper-zinc alloy, in the alloy to the independent phase exists, is a free mass distribution in the grain boundaries and intracrystalline, both lubricating effect, but also can make the chip into a crumbling shape, can improve the cutting and wear resistance of brass. Lead brass cutting and lead content is directly proportional to the amount of lead, but when the lead content of more than 3%, no longer significantly improve the cutting of copper, and reduce the hardness, strength and elongation of brass. Therefore, the main properties of lead brass can be summarised as wear resistance, corrosion resistance, good toughness.
Applications:
Leaded brass is mainly used in mechanical engineering in a variety of connectors, valves, valve stem bearings. In the electronics industry for precision corrosion-resistant parts, such as tape recorders, video recorders, cameras, clocks and watches and other electronic product parts.
