Spherical high quality tungsten powder has uniqueness and excellent serviceability. It has a spherical appearance, good powder flowability, and high tap density. It can be used as a high-tech material for thermal spraying, porous materials, powder metallurgy industries and other industries.
Applications
In the field of thermal spraying, spherical tungsten powder not only has good fluidity, but the coating obtained is more uniform and compact, so the product has higher wear resistance.
In terms of porous materials, porous tungsten made from spherical high quality tungsten powder has better voids, so it can control the permeability of the product according to process conditions during the production process. It is gradually replacing conventional tungsten powder for making porous tungsten parts. Such as cathode of high power pulsed microwave tube, helium tungsten cathode of electron tube, gas distribution plate at high temperature and gas filter material.
In the powder metallurgy industry, compacting of spherical high quality tungsten powders during the sintering process is very difficult to shrink and can achieve good dimensional control. The density distribution of the medicine mask made of spherical high-quality tungsten powder is uniform, thereby improving the characteristics of the jet formed by perforation and bombardment, and improving the penetration performance and stability of the perforating bullet.
