Tungsten Carbide fine gray powder Cas 12070-12-1

Short Description:

Tungsten Carbide is an important member of the class of inorganic compounds of carbon. It is used alone or with 6 to 20 percent of other metals to impart hardness to cast iron, cutting edges of saws and drills, and penetrating cores of armour-piercing projectiles.
