Grade: MG10 density 1.0-2.0 Specific Gravity: 14.2 Hardness: 87 Bending strength: 2900 Usage: stamping Tungsten / carbide there is a carbide is one or more (such as TiC, WC, etc.) as hardening compared to steel (such as high-speed steel, molybdenum chrome steel, etc.) powder as binder made of steel alloy called. Its hardness is between between steel and carbide, but the toughness and can greatly improve the machining and heat treatment processing. The typical hardness of steel Carbide: After quenching - tempering hardness 69 ~ 73HRC, high-speed steel 65%.
