Tungsten carbide is known for its hardness and high melting point. On the Mohs scale for testing hardness, tungsten carbide receives a rating of nine, surpassed only by diamonds, which have a hardness of 10. This hardness makes tungsten carbide very scratch-resistant.
Tungsten's atomic number on the Periodic Table is 74; its atomic symbol is W. The element is highly resistant to bases and acids. Tungsten's melting point of 3,422 degrees Celsius is the highest of any metal. Hard by itself, tungsten becomes even more durable when combined with carbon, as well as nearly scratch resistant.

Since being invented by German scientist in the beginning of 1920s, cemented carbide has been in market as widia and firstly applied in industries for making tungsten filament drawing dies, replacing the expensive diamond drawing dies.
Cemented carbides are metal materials made of carbides of one kind or several kinds of refractory metals and binding metals with powder metallurgy method.
On DEC 13, 2017, a new Indian customer came to our company to discuss the cooperation, and our clerk Tommy had a friendly reception.
December 7, 2017, although the sky is not beautiful, it still can not stop the enthusiasm of Indian customers to our company. Grace, our salesman, had a good reception for him and new orders came one after the other.
