What is the role of copper in the lead
Lead is a main element in the copper lead, it hardly dissolve in copper - zinc alloys, mainly in the independent phase at the grain boundary in Cu-Zn solid solution. It can be seen that the phase diagram of Cu Pb monotectic organization.
A large number of free lead particles dispersed in the copper matrix, there is a strong run sliding and friction reducing effect, the alloy exhibits excellent machinability, cutting brittle workpiece, the product surface is smooth, so lead copper with its easy cutting, easy forming and other excellent properties, is widely used in the joint, to make different shapes of parts, common brands such as C3604 brass rod, HPB59-1 brass rod, H62 brass bar.
