YK20 / YK05 Excellent Tungsten Carbide Button , Hot Working Performance Carbide Teeth Inserts
Introduction of tungsten carbide button:
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.
