Heat Treating of Copper and Copper Alloys

Diffusion and homogenization are slower and more difficult in tin bronzes, silicon bronzes and copper nickels than in most other copper alloys. Therefore, these alloys usually are subjected to prolonged homogenizing treatments before hot or cold working operations. The high-tin phosphor bronzes (above 8% Sn) are noted for extreme segregation.
