| Cast Tungsten Carbide Powder |
|
| |
Character: |
Gray particle and Gray powder |
Character: |
The eutectic structure of WC and W2C, its high melting point, high hardness, high wear resistance make it has characteristics of high temperature resistance, wear resístance, ímpact resistance. |
Applications: |
Cast tungsten carbide is used as a reinforcing material for hard facing of petroleum drilling tools. Building-material machines, cereals processing machines and other easi1y wearing components. Cast Tungsten Carbide has widely applications in Mining, Petroleum, Geological, Meta11urgy and Machine. |
