Product Description

Product Description

 

Manufacturer wholesale high-purity tungsten powder Wolfram Alloy products and metallurgy

Explain:
1. Tungsten powder has high purity, uniform particle size and good dispersion. It is an important raw material for producing tungsten carbide powder
Tungsten carbide powder is the main raw material for processing cemented carbide, which has more excellent properties.
2. Tungsten powder not only has high hardness, but also has the characteristics of wear resistance, corrosion resistance and high temperature resistance.
3. The melting point of tungsten is 3400 º C. Boiling point 5555 º C, insoluble in water, acid and alkali resistant.
Tungsten is the hardest metal. The hardness of sintered tungsten rod is 200~250, and the hardness of tungsten rod passing through rotary hammer is 350~400.
Properties:
Tungsten powder is a kind of powdery tungsten metal, which is the raw material for preparing tungsten processing materials, tungsten alloys and tungsten products.
Storage conditions:
Tungsten powder shall be stored in a dry, cool and sealed environment and shall not be exposed to the air. In addition, heavy pressure shall be avoided and it shall be transported as ordinary goods.

Applications

Tungsten powder is the main raw material for processing powder metallurgy tungsten products and tungsten alloys. Pure tungsten powder can be made into processed materials such as silk, rods, tubes and plates, and certain shaped products. Tungsten powder is mixed with other metal powders to form various tungsten alloys such as tungsten-molybdenum alloy, tungsten-rhenium alloy, tungsten-copper alloy and high-density tungsten alloy. Another important application of tungsten powder is to make tungsten carbide powder, which is used to prepare cemented carbide tools such as turning tools, milling cutters, drill bits and molds.

Storage conditions

This product should be stored in dry, cool and sealing of the environment, can not be exposure to air, in addition should avoid the heavy pressure, according to ordinary goods transportation.
