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.
Copper Alloy Powder Production Process
Step 1: High Quality Cu Sn Zn Pb Material
Step 2: Melting
Step 3: Atomized
Step 4: Diffusion
Step 5: Filter
Step 6: Dry
Step 7: Grading
Step 8: Inspection
Step 9: Packing
Copper Alloy Powder includes copper tin alloy powder
(bronze powder), copper zinc alloy powder (brass powder)
copper iron alloy powder, copper lead alloy powder etc.
Copper Coating iron Powder includes copper coating
iron powder, bronze coating iron powder, brass coating
powder. This is best material used in Oil bearing bushing.
