Product Description

Spherical tungsten powder has a melting point of 3400℃ and boiling point of 5555℃. Tungsten powder is the hardest metal material.
Tungsten powder is the main raw material for processing powder metallurgy tungsten products and tungsten alloys. It can be made into wire, rod, tube, plate and other shaped products. Tungsten powder can be mixed with other metal powders to make various tungsten alloys, such as tungsten-molybdenum alloys, Tungsten rhenium alloy, tungsten copper alloy and high density tungsten alloy, etc.
Main properties:Spherical tungsten powder has high purity (99.95%), small particle size (50nm), low oxygen content (<200ppm), good sphericity (>95%), fewer satellite balls, and good fluidity.

Product Features

This product should be stored in a cool, dry room to avoid heavy pressure. It should not be exposed to the air during use, so as to avoid moisture absorption and agglomeration, which will affect the dispersion performance and use effect. Unused products should be sealed or stored in a vacuum after unpacking.
