The purity of high purity tungsten powder is 5N or 6N, and it is obtained by reducing high-purity ammonium paratungstate. High-purity tungsten powder and its silicide are used to prepare metal targets, used as resistance layers, diffusion barriers, etc. in ultra-large-scale integrated circuits, and as gate materials and connection materials in metal oxide semiconductor transistors.

The chemical formula of tungsten disulfide is WS2. It can be used as a lubricant, especially as a solid lubricant under high temperature, high pressure, high load and high vacuum conditions. It performs better than molybdenum disulfide and has a lower friction coefficient and greater compressive strength.

Sodium tungstate has a wide range of uses. In addition to being used to make ammonium paratungstate, ammonium metatungstate, tungstic acid, tungsten trioxide, metallic tungsten, tungsten carbide, and cemented carbide, it can also be used in petrochemical catalysts, electroplating, textiles, flame retardants, water treatment, dyes, pigments, inks, etc.

Tungsten wire can be processed into extremely fine specifications, offering significantly enhanced strength and hardness compared to stainless steel of similar specifications. 

The tungsten copper block, measuring 34x33x15mm and composed of 80% tungsten and 20% copper, is a composite material produced through powder metallurgy. 

A fine tungsten rod with a diameter of 1.0 mm and a length of 38 mm is a small bar made of high-purity tungsten, 

Tungsten heating rods are electric heating elements made from high-purity tungsten material, 

The barium tungsten cathode is a high-performance thermionic cathode composed of a porous matrix filled uniformly with barium salts.

The WL20 lanthanum tungsten electrode is a tungsten-based alloy electrode material that contains approximately 2% lanthanum. 

The 70WC30Cu tungsten carbide copper rod is a composite material typically composed of 70% tungsten carbide and 30% copper. Due to the unique combination of tungsten carbide and copper, this material possesses exceptional physical and chemical properties.
