Product Description
Tungsten Cemented Carbide Rock Drilling Button Bits

1.What is Tungsten Carbide?
 
Tungsten carbide (chemical formula: WC) is a chemical compound (specifically, a carbide) containing equal parts of tungsten and carbon atoms. In its most basic form, tungsten carbide is a fine gray powder, but it can be pressed and formed into shapes for use in industrial machinery, cutting tools, abrasives, armor-piercing rounds, other tools and instruments, and jewelry.?
 
2.How cemented carbides are made?

Carbides are made by blending micron-sized tungsten carbide and cobalt powders, then compacting the mixture in a mold and sintering the molded part at a temperature high enough to cause the cobalt to flow. During this process the cobalt fills the voids between the tungsten grains and thoroughly coats each grain. When the cobalt solidifies, it cements; the grains together, forming a dense composit. Cemented carbides get their hardness from the tungsten grains and their toughness from the tight bonds produced by the cementing action of the cobalt metal. By varying the amount of cobalt we can change the hardness, wear resistance and toughness (shock resistance) of the carbide to suit your particular tungsten carbide needs. Tungsten carbide (wc) is called by some to be the hardest metal but it is actually a metal matrix composite.
