A tungsten retaining ring is a precision-engineered component typically made from tungsten. 

Silver-tungsten rod is a composite material made from silver and tungsten, combining silver's high electrical conductivity with tungsten's high hardness and wear resistance. 

Gold-plated tungsten wire is a material in which a 0.2-0.4 micron layer of 24K gold is plated onto the surface of tungsten wire, 

A tungsten probe is a precision tool made from high-purity tungsten, widely used in semiconductor testing, electronic component inspection, and microscopic operations.

Tungsten twisted wire for electric light sources is a key material widely used in various bulbs and light sources. It features a high melting point, high strength, excellent electrical conductivity, and corrosion resistance. It is primarily used in incandescent lamps, halogen lamps, fluorescent lamps, and high-intensity gas discharge lamps.

Silver-tungsten rods are a composite material that combines the excellent properties of both silver and tungsten. 

Tungsten wire can be used to manufacture anti-static gloves, effectively preventing static accumulation and protecting sensitive electronic components.

According to GB/T 26033-2010 Ammonium Metatungstate, ammonium metatungstate is divided into two grades based on different production processes: AMT-P and AMT-J. Among them, AMT-P is the product produced by spray method, with WO3 content generally ≥ 90%; AMT-J is a crystallization process product, with WO3 content generally ≥ 81.5%.

Ferro tungsten is an iron alloy primarily composed of tungsten and iron, with a tungsten content generally ranging from 75% to 85%. Ferro tungsten has excellent properties such as high density, high strength, wear resistance, and corrosion resistance. It is a crucial material for refining high-speed tool steel, alloy structural steel, magnetic steel, heat-resistant steel, and is indispensable in the steel industry and mechanical casting industry.

Riveting requires the use of a rivet gun and a tungsten alloy bucking bar. Typically, the bucking bar is designed in various shapes and sizes depending on the rivet gun being used. In some cases, dedicated tungsten bucking bars may be designed for specific riveting tasks.
