copper tungsten bar diameter : 1.5-100mm length :50-1000mm density :12.6-17.05 g/cm3 composition : W55-90% Cu bal

copper tungsten bar

The surface treatment method have : sintering surface ,forged surface , groud surface .

The manufacturing process is as follows : press the refractory metal . sinter the pressed compact at a high temperature , and infiltrate it with copper , all this is fone under very closely controlled condtions . The result is a relatively hard material with superior arc and wear resistance , high physical properties :at elevated temperatures ,and good electrical and thermal conductivity.
