CNPC POWDER copper alloy powder (bronze powder and brass powder) with tin, zinc, lead and other elements are produced by the process of powder metallurgy. They have the physical and mechanical properties of their cast or wrought counterparts.Copper alloyed with iron powder reinforce the mechanical properties and control dimensional changes during sintering, the addition being made either by mixing or by infiltration. Copper Powders have good strength, thermal conductivity, wear resistance, color and gloss.

Copper coating iron powder is the process of plating copper on surface of the iron powder. The color is the same as copper powder. It's instead of copper powder sometimes. It's cold be reduce the cost.
