1. Introduce
– It has the highest tensile strength among pure metals and has the highest tensile strength even at temperatures above 1500℃
– Due to its high melting point, it is mainly used to manufacture alloy steels such as tungsten steel and high speed steel, and is also used in the electrical field due to its excellent high temperature properties.
– W alloying element effect : high temperature hardness, wear resistance improvement, inhibition of carbide growth when maintaining high temperature for a long time
2. Property
– Excellent hardness, wear resistance, heat resistance
