Iron tungsten alloy series (tungsten content: 70%-80%) is an alloy composed of tungsten and iron, which is used as an alloy additive in steelmaking. Commonly used ferrotungsten alloys contain 70% tungsten and 80% tungsten.
Tungsten steel, also known as cemented carbide, refers to a sintered composite material containing at least one metal carbide. Tungsten carbide, titanium carbide, and tantalum carbide are common components of tungsten steel.
Tungsten products refer to all kinds of products at all levels produced with tungsten ore as the basic raw material. Tungsten products can be divided into tungsten ore, tungstate, tungsten powder, pure tungsten products, tungsten alloy, cemented carbide, other derivatives of tungsten, etc.
Tungsten-copper alloys are pseudo-alloys of refractory metals, so tungsten-copper alloys can only be produced by powder metallurgy. The manufacture of tungsten copper tube is a bigger challenge in production process.
Tungsten copper alloy combines the advantages of tungsten and copper, high temperature resistance, arc ablation resistance, high hardness, high melting point, high strength, high specific gravity, high electrical conductivity, high thermal conductivity, easy cutting, anti-adhesion, and has the characteristics of sweating and cooling
Tungsten is used as electrical contact or contact material, which is resistant to arc ablation; good fusion resistance; metal surface evaporation caused by electrothermal action, less transfer and consumption;
Tungsten-copper alloy material has the advantages of both tungsten and copper. Tungsten is resistant to high temperature (greater than 3000 degrees) and is therefore resistant to burnout.
Tungsten rods have special properties such as low thermal expansion and good thermal conductivity, sufficient resistance to electrical resistance, and high elastic modulus. Therefore, tungsten rods are widely used in various fields.
Producing tungsten wire is a complex and difficult process. The whole process must be strictly controlled by controlling the proper chemical composition to ensure the physical properties of the finished tungsten wire.
The tungsten powder is prepared by isostatic pressing and then sintered at high temperature into a tungsten slab. After the tungsten slab is rolled by a rolling mill, the tungsten plate and tungsten sheet are cut and formed by a shearing machine.
