The welding method of copper bonded tungsten copper electrode is silver brazing, which is the most popular in our workshop.

There are many kinds and types of gift made by tungsten, such as tungsten ring, tungsten bracelet, tungsten pig, etc. however, what I would like to recommend is a special one - tungsten gift card.

Tungsten iridium stream mouth is made of a body of tungsten and inserted a tube made of iridium, instead of the whole part to be an alloy of tungsten and iridium.

Copper bonded tungsten electrode is bonded two different materials with high and low electric conductivity for spot welding in car industry.

1. What is Tungsten Boride?

Tungsten boride is compound of tungsten and boron. Its most remarkable property is high hardness.

1. Nano Tungsten Trioxide

Nano tungsten trioxide has a large specific surface area and significant surface effect. 

1. What is Tungsten Disulfide?

Tungsten disulfide is an inorganic chemical compound composed of tungsten and sulfur with the chemical formula WS2.

2.Tungsten Disulfide Property

Physical property

Chemical formula is composed by one molecular of tungsten, two molecular of sulfur. Appearance is grey powder. Stable in the air, insoluble in water, alcohol, dilute nitric acid and sulfuric acid. CAS number is 12138090.

Chemical property

Main content of tungsten disulfide is tungsten disulfide with over 99.9 percent. Other impurity content such as ferro, aluminum, arsenic, bismuth are controlled within limits according to national standard.

3.Tungsten Disulfide Producing Process

Synthesize tungsten powder and sulfur powder in the atmosphere of pure nitrogen under 800~900℃, it will obtain tungsten disulfide

4.Tungsten Disulfide Application

Tungsten disulfide application includes high-grade carbon brush wear-resistant lubricant,lubricating agents in solid lubricants, for the production of self-lubricating parts and PTFE and nylon and other materials, solid anti-friction coating.

1.What is Tungsten Hexachloride?

Tungsten hexachloride is the chemical compound of tungsten and chlorine with the formula WCl6. This dark violet blue species exists as a volatile solid under standard conditions.

2.Tungsten Hexachloride Property

Physical property

Chemical formula is composed by one molecular of tungsten, six molecular of chloride. Appearance is purple crystalline, moisture sensitive. Molecular Weight is 396.61. Soluble in water and chlorocarbons. It is an aggressively corrosive oxidant, and hydrolyzes to release hydrogen chloride.

Chemical property

Main content of tungsten hexachloride is tungsten chloride with over 99.9 percent. Tungsten content is no less than 43%, chlorine content is no less than 53%.

3.Tungsten Hexachloride Producing Process

Tungsten hexachloride can be prepared by chlorinating tungsten metal in a sealed tube at 600 degree celsius.

4.Tungsten Hexachloride Application

Tungsten hexachloride application includes catalyst in synthesis of engineer plastics PDCPD, refine of high purity tungsten and preparation of WC, precursor of nano particle tungsten.

Manganese tungstate is yellow odorless powder, can not be dissolved, the storage should avoid light, fire and high temperatures.

Magnesium tungstate is of white powder cubic crystal, monoclinic structure, is self-activated fluorescent material.
