What are the production processes for tungsten alloys? What are the issues?

June 12, 2023

Tungsten Alloy is a very important industrial material, commonly used in the manufacturing of industrial equipment such as high temperature, high pressure, corrosion resistance, and wear resistance. Its manufacturing process involves a variety of processes, such as the production of tungsten powder, the powder metallurgy process of tungsten alloy, Hot working and plastic processing.

The production process of tungsten alloy mainly includes the following steps:

Tungsten extraction: The main raw material for Tungsten Alloys is tungsten ore, which is mainly composed of calcium tungstate and ammonium tungstate. When extracting tungsten, the Tungstate in the mineral must be first reduced to tungsten oxide, and then the tungsten oxide is reduced to pure tungsten with hydrogen.

Production of tungsten powder: Refined tungsten is made into tungsten powder, usually using hydrogen gas as a reducing agent to reduce tungsten oxide into tungsten powder. In addition, another method of producing tungsten powder is to melt the tungsten rod with an electric arc to form very small tungsten particles.

Powder metallurgy process: In the manufacturing of tungsten alloys, powder metallurgy process is generally used. Firstly, tungsten powder is mixed with additives, followed by compression molding, followed by high-temperature sintering to form a hard alloy material with tungsten powder and additives.

Hot working: Hot working is to heat the Hot working parts to a high temperature state before processing. Such as forging, extrusion, rolling, stretching, and forging of tungsten alloys.

Plastic processing: Plastic processing technology is widely used, such as compression molding, fluorescent extrusion molding, cold rolling, spinning, stamping and other manufacturing technologies.

However, there are also some problems in the production process of tungsten alloys. One important issue is that tungsten products are prone to fracture during processing, as tungsten is a very brittle material. In addition, tungsten alloys have high melting points, are difficult to process, and are prone to damage, which also puts forward high requirements for material selection and treatment.

In addition, tungsten ore resources are very limited. The major tungsten minerals in the world are China, Russia, Canada, Australia, etc. Therefore, if the production of tungsten alloys continues to increase, it may cause a shortage of tungsten ore supply. In addition, the production process of tungsten alloys also generates a large amount of waste, which poses a certain threat to the environment.

In summary, the production process of tungsten alloys is a very complex and difficult task that requires multiple processing and treatments. In the production process, it is necessary to continuously improve the processing technology, improve production efficiency, and reduce manufacturing costs. At the same time, it is also necessary to strengthen environmental protection and resource management to ensure the sustainable development of the tungsten alloy industry.
