Single phase tungsten carbide powder has the advantages of good plasticity, high hardness and complete crystallization. It is an important raw material for the preparation of tungsten carbide, and the storage period is 6~8 months.
Characteristic
Single phase tungsten carbide powder has complete carbonization, good plasticity. It also has high hardness, less structural defects, and complete crystal development. Its internal structure features no W2C phase, few micropores, few grain boundaries, and large crystal grains.
Application
Single phase tungsten carbide powder is an important raw material for the preparation of hard alloys, and can produce hard alloy materials with high hardness, high wear resistance and high toughness, and its performance is significantly improved compared with conventional hard alloys.
Preparation
Single phase tungsten carbide powder can be obtained by carbonization of medium-grain tungsten powder at high temperatures above 1800°C.
Storage
The storage period is limited to 6 months and cannot exceed 8 months at most. Otherwise, it can only be used to suppress the better workpieces in stress conditions.
