What is tungsten powder? Tungsten powderis stable below 630 ℃, converted to tungsten at above 630 ℃, and this process is irreversible. In addition to certain requirements for impurity content, tungsten powder oxygen content should be controlled within a certain range. The grain size of commonly used tungsten powder is generally 2~10 of the average grain size μ M. Tungsten powder is polygonal particle shape. In addition, the specific surface, loose density, and shake density of tungsten powder also vary within a certain range. The performance of tungsten powder directly impacts the production of tungsten materials, and the quality of tungsten powder metallurgical products, especially the impact of purity and particle size, is more obvious. Tungsten powder is classified according to purity, particle size, and different uses.
Main characteristics of tungsten powder Nanometer tungsten powder and micron tungsten powder are prepared by variable current laser ion beam gas phase method, with uniform particles, high activity, and large specific surface area. The oxygen content of the powder can be controlled below 1% after passivation treatment. Nanometer tungsten powder is applied to aerospace alloys, electronic packaging alloys, electrode materials, micro-electronic films, sintering aids, protective coatings, gas sensor electrodes, etc. It is used to manufacture high-performance tungsten products and process and manufacture nano-Wu wires; It has become an indispensable functional material in many high-tech fields to use the excellent performance of nano-Wu wire to manufacture high-performance nanocrystalline alloys and high specific gravity alloys. The cemented carbide produced by nano-Wu powder has high hardness and is the leading edge product of tungsten materials.
Uses of tungsten powder and nano tungsten powder 1. It is widely used in high specific gravity alloy, alloy steel, drill bit, anvil, and other large products 2. Highly active nanometer tungsten powder can be used as an additive for the raw material powder of high performance and high specific gravity alloy (the addition amount is from 10% to 20%) and the raw material additive for the preparation of W bars and W wires, and can also be used as the raw material of tungsten powder of high-performance alloy, which can improve the properties of the alloy, reduce the sintering temperature and shorten the sintering time, and save production costs 3. The nanometer tungsten powder can be used as the raw material of nanometer WC to prepare nanocrystalline cemented carbide. Due to the special pore structure of this nanometer tungsten powder, it can be used as the raw material of tungsten powder for the W-Mn method of ceramic metallization coating 4. Spherical tungsten powder can also be used as metal 3D printing material.
Price of tungsten powder Tungsten powder particle size and purity will affect the product's Price, and the purchase volume can also affect the cost of tungsten powder. A large amount of large amount will be lower. The Price of tungsten powder can be found on our company's official website.
