Nano tungsten powder and ultrafine tungsten powder feature uniform particles, high activity, and a large specific surface area. Through passivation treatment, the oxygen content of the powder can be regulated to stay below 1%.
Nano-tungsten powder finds extensive applications in various fields. It is used in aerospace alloys, electronic packaging alloys, electrode materials, microelectronic films, sintering aids, protective coatings, and gas sensor electrodes, among others. It plays a crucial role in manufacturing high - performance tungsten products and is utilized in the processing and production of nano - tungsten wires. The outstanding properties of nano - tungsten wires are harnessed to fabricate high - performance ultra - fine nanocrystalline alloys and high - density alloys, making nano - tungsten powder an essential functional material in numerous high-tech fields.
The cemented carbide fabricated with nano tungsten powder exhibits extremely high hardness and stands as a leading - edge product in the realm of tungsten materials.

Application
1. It is widely used in high-density alloys, alloy steel, drill bits, top hammers and other large products;

2. Highly active nano-tungsten powder can be used as an additive for the raw material powder of high-performance and high-density alloys (addition amount ranges from 10% to 20%) and as a raw material additive for the preparation of W strips and W wires, and also as a raw material for high-performance alloys. It can improve the performance of the alloy, reduce the sintering temperature and shorten the sintering time, and save production costs;

3. The nano-tungsten powder can be used as the raw material of nano-WC to prepare nano-crystalline cemented carbide. Due to the special pore structure of this nano-tungsten powder, it can be used as the raw material of tungsten powder for ceramic metallization coating W-Mn method

This powder is produced in spherical form, which makes it highly suitable for applications like additive manufacturing (3D printing), thermal spraying, and powder metallurgy. Its spherical shape ensures excellent flowability and packing density, which are critical for precision manufacturing processes.
