Other Metal / Alloy powder
In the welding world. except the Ferroalloy powder, there are a lot of other metal and alloy powder which pay an important role in the welding materials, such as Mo powder, CrC powder, Cr powder, Cobalt powder, Cast WC powder.etc
These Metal and alloy powders show follows characters
- pure Metal, low S,P content
- impove the coating hardness and anti-corrosion performance
- degassing, de-oxygen function
- improve the wear resist ablity of coating.
