High-Purity 99% Tungsten Powder CAS 7440-33-7

What is Tungsten?

Tungsten has good thermal and electrical conductivity. It has a very high density, the highest density among all known elements. It usually exists in powder form. The hardness of tungsten is the hardest among metals. The hardness HB (kgf/mm2) of sintered tungsten bars is 200-250, and that of tungsten rods after rotary hammer is 350-400. It is soluble in a mixed acid of nitric acid and hydrofluoric acid. It melts with a mixture of sodium hydroxide and sodium carbonate. It is slightly soluble in nitric acid, sulfuric acid, and aqua regia; it is insoluble in water, hydrofluoric acid, and potassium hydroxide.

1. Most of tungsten is used to produce cemented carbide and ferrotungsten.
2. Metal tungsten wire, rod, sheet, etc. are used to make light bulbs, parts of electron tubes and electrodes for arc welding.
3. Tungsten and tungsten alloys have excellent hardness and wear resistance and are often used to make cutting tools, drills and tungsten wires.
4. It can be used to manufacture aerospace, missiles, nuclear reactors and other fields with high temperature and high strength requirements.

1. Tungsten is a relatively safe material that does not react or corrode with water.
2. Tungsten powder can form flammable dust in the air, so attention should be paid to fire prevention and static electricity accumulation.
3. It and its compounds are non-toxic to the human body, but long-term exposure in a high concentration environment may cause tungsten industrial disease.
