Violet tungsten oxide is a defect state of tungsten oxide with very novel physical and mechanical properties. It is not only used in the chemical industry, but also widely used in automobile manufacturing, mechanical processing, aerospace, chemical battery, electronic information and other fields. 

Polymer tungsten CT protective clothing is a new type of lead-free medical protective products. Its X-ray shielding rate can reach 99%. And it is much lighter than traditional lead protective clothing, so it is more suitable for providing X-ray protection for patients and medical staff.

Tungsten electrodes have been so popular for TIG welding and GTAW welding, including cerium doped, lanthanum doped, yttrium doped, thorium doped, zirconium doped, etc. 

Tungsten alloy medical ray protective material is tungsten-nickel-iron alloy or tungsten-nickel-copper alloy used for shielding medical radiation sources such as X-rays and gamma rays. The difference between the two tungsten alloy materials is that tungsten-nickel-iron alloy has certain ferromagnetism, and its mechanical properties and processing properties are superior to tungsten-nickel-copper alloy.
