Taiwan tungsten steel G5: Hardness: 84 Tensile Strength: 2800 high hardness, toughness, wear resistance, mainly used for tensile modulus, powder molding, textile wear parts, valve parts, bearing parts, stamping dies, extrusion pressure deep drawing sheet metal wire roll, a large powder compaction mold. Tungsten / carbide is mainly composed of the hard phase and binder phase composition of the powder product. Hard hard phase, mainly a variety of carbides. The main carbide are: tungsten carbide (WC), titanium carbide (TiC), tantalum carbide (TaC) and niobium carbide (NbC). In most cases, cobalt used as binder phase. In Carbide plant, Carbide after mixing, pressing and sintering.
