1.Tungsten powder has high purity, particle size uniform dispersion of good, and is an important raw material of producing cemented carbide, tungsten powder can make hard alloy and has many more excellent properties. 2.Tungsten powder not only has high hardness, hard king outside, but has wear resistance, corrosion resistance, temperature resistance, etc. 3.The melting point was 2860°C±50°C, boiling point was 6000°C, and it also insolubles in water, strong acid resistance, high hardness and elastic modulus.
