Tungtsen Powder

Penerangan produk
Tungsten powder is the main raw material for processing powder metallurgy tungsten products and tungsten alloys. Pure tungsten powder can be made into silk, rod, tube, plate and other processing materials and certain shape products. Tungsten powder mixed with other metal powder can be made into a variety of tungsten alloys, such as tungsten molybdenum alloy, tungsten rhenium alloy, tungsten copper alloy and high density tungsten alloy.

Application of Tungtsen Powder
The important application of tungsten powder is to make tungsten carbide powder, which is then used to make carbide tools, such as turning tools, milling cutters, drill bits and dies.
Production Process of Tungtsen Powder
It is prepared by hydrogen reduction of tungsten trioxide or ammonium paratungstate. The process of making tungsten powder by hydrogen reduction is generally divided into two stages: in the first stage, tungsten trioxide is reduced to tungsten dioxide at the temperature of 500~700oC; In the second stage, tungsten dioxide is reduced to tungsten powder at the temperature of 700~900oC. The reduction reaction is usually carried out in a tubular furnace or rotary furnace.
