Carbide mould parts: an industrial tool with high strength, hardness and wear resistance

Tungsten steel material is an alloy material made of WC and Co powder as the main raw material, which is mixed, pressed and sintered by a series of processing technology using powder metallurgy method. It has the characteristics of hardness, high strength, corrosion resistance and stainlessness. Tungsten steel, also known as cemented carbide, is a metal material with high strength, high hardness and wear resistance. It is an alloy of tungsten (a very hard metal) and other elements such as cobalt, titanium and chromium. Due to its unique physical and chemical properties, tungsten steel has a wide range of applications in many industrial fields, including aerospace, military, automotive manufacturing, and cutting tool manufacturing.

Tungsten steel has a very high hardness that can reach HRA90 and above, which is unmatched by most other metal materials. This gives tungsten steel an unrivalled advantage in applications where high strength and hardness are required. For example, in the aerospace industry, tungsten steel is used to make turbine blades for aircraft engines, as these components are required to operate at extremely high temperatures and pressures that only tungsten steel can meet.

In addition, tungsten steel has very good wear resistance. This is because the carbide particles in tungsten steel can form a hardened layer during wear, which increases the wear resistance of the material. This gives tungsten steel an advantage in applications where wear resistance is required. For example, in the manufacture of cutting tools, tungsten steel is used to make tools such as drills and milling cutters, which are required to work at high speeds and high temperatures, which only tungsten steel can fulfil.

However, tungsten steel also has some disadvantages. Firstly, the price of tungsten steel is very high, this is because tungsten is a rare metal and its price is affected by the supply and demand in the market. Secondly, tungsten steel is difficult to machine, this is because tungsten steel has high hardness and is prone to tool wear and cutting heat during machining. Finally, tungsten steel has poor impact resistance due to its low toughness, which makes it susceptible to fracture upon impact. Despite these drawbacks, tungsten steel is still widely used in many industrial fields due to its unique properties. With the development of science and technology, new tungsten steel alloys and processing techniques are being researched to overcome the shortcomings of tungsten steel and to further improve its performance and range of applications.
