CNPC POWDER'S atomized copper powder is produced by the water atomization (pure copper powder) or gas atomized (spherical copper powder) methods. The copper powder comes in a pure fine powder form, including irregular and spherical shape. Cu content is 99.7% min. CNPC Copper powder properties of formability, inoxidizability, compressibility, sintering activity and well-developed surface are well-fitted in PM industry.
Copper Powder Production Process
Step 1: High Quality Copper Material
Step 2: Melting
Step 3: Atomized
Step 4: Filter
Step 5: Collect
Step 6: Dry
Step 7:Grading
Step 8: Inspection
Step 9:Packing
The difference between Water Atomized Copper Powder and Gas atomized Copper Powder is their apparent density, particle shape, oxygen
content and color.
Apperent Density Particle Shape Oxgyen Content Color
Water 2.3-3.5g/cm3 irregular 0.3% darker
Gas 4.5-5.2g/cm3 spherical 0.1% light
