AC contactor is applied tungsten copper or tungsten iron contact as main connecting parts. AC refers to alternative current. Why tungsten contacts are selected for the contacts of AC contactors? Tungsten as raw material made contacts are with superior properties.

Tungsten alloy weight is used in golf to increase the weight of golf head. In order to improve the performance of golf clubs, the weight is added to the golf end. Compared with traditional weights (iron, lead, steel, zinc, etc.), tungsten alloy is more suitable as a weight for golf heads.

Barium tungsten electrode is with characteristics of low electron work function, high electron current density, better starting performance and low temperature resistance, and is often used in the field of xenon flash lamps.

A fabrication process of tungsten oxide (WO3) nanoplates with ammonium paratungstate has been performed, the product showed great photocatalytic activity due to the plate-like shape.

Ammonium paratungstate (APT) has been used as precursor material in production of Hexagonal tungsten trioxide (h-WO3) microspheres by hydrothermal synthesis. The as-prepared product showed significant catalytic activity in the hydrogenation of styrene under mild environment.

Solid acid catalysts play a significant part in chemical and petroleum industries in hydrocarbon conversion reactions required in octane enhancement processes, such as cracking, isomerization and alkylation, which can form highly branched isoparaffins. Such reactions need strong or moderate acid catalysts. However, halide-type solid acids have a great negative effect on environment. Tungsten oxides supported on oxide carriers have been considered as a more environmental-friendly substitute. Therefore, it has been well studied to be catalysts for hydrocarbon isomerization processes.

Single-walled carbon nanotubes (SWCNTs) have been an area of intense research since their discovery in 1993, owing to their extraordinary mechanical and unique electronic properties. It has been applied in fields including field-emission, SPM tips, and sensors.

Tungsten nanopowder has been widely applied in industrial catalysis, hard materials, thermionic cathodes, and high-power batteries due to its highly oxophilic characteristics. tungsten is the hardest metal in the world, which makes it resistant to acids, alkalis, and oxygen.

WC-Co cemented carbide has widely used in machining, drilling, automotive, military, and aerospace owing to its excellent mechanical performances. Most research on cemented tungsten carbides with a cobalt binder (WC-Co cemented carbides) has focused on improving their strength, fracture toughness, and hardness.

Tungsten is an important and prominent metal among the refractory metals due to an excellent combination of outstanding high temperature properties and high melting point (highest of all metals). Its high strength and corrosion resistance at elevated temperatures, good thermal conductivity and low thermal expansion makes it possible to use tungsten in high temperature applications. On the other hand, owing to its high hardness and wear resistance, high modulus of elasticity and compression strength, tungsten is an important constituent as an alloying element in tool steel, superalloys, stellites and hard metal industry.
