Description	Tin-lead bronze flange ring is a kind of non-magnetic, conductive, thermal conductivity, corrosion resistance is very good.Therefore, when used in heat exchanger, pressure vessel and other high temperature and high pressure sealing parts, it can effectively prevent the fragmentation of gasket and the erosion of medium.

Lead is actually insoluble in the copper-tin alloy and is distributed in the interdendrite as a single phase black inclusions.Lead is not easily distributed evenly in ingots, and a small amount of nickel is usually added to improve the distribution and refine the microstructure.Lead reduces the friction coefficient of tin bronze, improves the wear resistance and machinability, but slightly reduces the mechanical properties.3% ~ 5% zinc is often added to the copper-tin-lead alloy to improve its mechanical properties.The addition of 0.02%-0.1% zirconium or 0.02%-0.1% boron, especially the addition of 0.02%-0.2% rare-earth elements, can refine the lead particles and make them evenly distributed, so as to improve the microstructure, casting and mechanical properties of lead-containing tin bronze.
