Flake Copper Powder

Product Parameter

Flake copper powder information: 
The concentrated metal scraps, obtained by the mechanical process for waste printed circuit board (WPCB) recycling, were pressed as the anode, which was directly electrolyzed to produce copper powders.
The effects of CuSO4·5H2O, NaCl and H2SO4 concentration, current density and electrolysis time on current efficiency and copper powder size were investigated in detail.
The results indicated that current efficiency increased rapidly as the increase of CuSO4·5H2O, H2SO4 concentration and current density.

Other information:
A study and the results on the sintering kinetics of the flake copper powder during Micro-FAST for the fabrication of micro-gears (the module is 0.2 and the pitch diameter 1.6 mm) from copper powder.
The results showed that the densification of flake copper powder is related largely to the bulk plastic-deformations of the particles and the melting of the particles at contact interfaces.
