Technical Parameters

Note: according to user requirements of nano particle can provide different size products.

Product performance

        1 Nano-Tungsten carbide powder, has high purity, particle size uniform dispersion of good, is an important raw material of producing cemented carbide, nano tungsten carbide powder can make hard alloy has many more excellent properties；

        2 Nano-Tungsten carbide powder except has high hardness, hard king outside, still has wear resistance, corrosion resistance, temperature, etc；

        3 The melting point was 2860°C±50°C, boiling point was 6000°C and also insoluble in water, strong acid resistance, high hardness and elastic modulus.

Application direction

        1 Nano-Tungsten carbide powder applied in composite materials, improve its performance: Nano-Tungsten carbide-cobalt (WC-Co) composite performance carbide powder preparation is the main raw materials and wear-resisting coating. Such as: cutting tools, computer, machinery, etc;
        2 Nano-Tungsten carbide powder appropriate under high temperature on mechanical processing, can produce cutting tools, kiln of structural materials, the jet engines, gas turbines and nozzle, etc.

Storage conditions
