Tungsten copper bar is a mixture of tungsten and copper.It is composed of tungsten powder and copper powder.How are tungsten copper bars made?First, the mixture of tungsten powder and copper powder is pressed into a bar through a mold,and then sintered in a high-temperature furnace. Finally, it has a ground finish.The high hardness tungsten copper bars are produced.Rosen manufacture various size tungsten copper bars.Include copper tungsten square bar and rectangular bar.Our tungsten copper bar meets ASTM B702 standard.
Application of Copper Tungsten Bar:
- Resistance welding
- EDM Electrode
- Heat sink
- Electronic packaging materials
