Microcrystalline tungsten powder has excellent performance characteristics. It is used in thermal spraying and high temperature resistant parts coating materials and diamond nesting materials. It is also a carcass material for manufacturing oil drilling tools.
Application
Microcrystalline tungsten powder is often used to spray high temperature resistant component coating material and diamond nesting materials. These materials sprayed is required high surface hardness, good toughness, wear resistance and corrosion resistance.
Microcrystalline tungsten powder is a carcass material for the manufacture of oil drilling tools - diamond drill bits. Therefore, the Microcrystalline tungsten powder has the characteristics of complete particle crystallization, uniform powder particle size, good fluidity, high bulk density and compaction density.
Preparation
High quality Microcrystalline tungsten powder can be obtained through the optimization of tungsten powder mixing, grading screening, pickling water washing, hydrogen drying, batch processing, etc. The density of Scott can reach 7.3~8.9g/cm3; tap density 9.0~10.5g/cm3; sieve is divided into +60mesh ≤2%, -325mesh≤10%; Fibonacci granularity is 35~40μm; improving mobility and reducing oxygen content.
