Metallurgy Of Tungsten Carbide Powder

In recent years, metallurgy technology of tungsten carbide powder developed rapidly. Sintered casting, temperature and pressure skills, injection molding, sinter hardening are used more and more widely. At present, powder casting is a primary forming skills in tungsten carbide powder metallurgy mechanical parts industry. Its shape has been changed by hot forging or cold forging. It has completed high density.

Chinese car and motorcycle market have very great potential. On one side, the motorcycle is still occupy the first market. But with a series of resolution and plan have been carried out, motorcycle market will be further expanded in the China West. On the other hand, the current national car market carried out another round of market competition.The revival and development of this occupation offered key point to tungsten carbide powder metallurgy.

From the international development trend, carbonized tungsten powder metallurgy gear can reduce the advantages of parts components and attracted more and more attention to the field due to its cheap price. For example, the number of each tungsten carbide powder metallurgy part in car has been increased quickly in the area of north America and Europe since 1990.

  

Improve Service Life Of Tungsten Carbide Die

Tungsten carbide die a kind of composite material that made by powder metallurgy method. Tungsten carbide has high hardness and good wear resistance. It owns high elastic modulus and working temperature. Tungsten carbide can made for som dies. While the service life of dies also could improved several times and even more than dozens of times. Tungsten carbide is regarded as die material, and is mainly used for drawing die, cold extrusion with little impact force and cold punching mold. At present, China can produce each types of tungsten carbide and basically meet the needs of the domestic market.

In order to improve the service life of tungsten carbide die, people had better pay attention to following tips.

Firstly, the selection of tungsten carbide die and hot treatment for insert all should obey the rule of national standards and specifications. At the same time, people who use the tungsten carbide die had better maintain it in time and ensure that the die steel will not be rust and alloy core oxidation. Secondly, structure of tungsten carbide die must be reasonable. Finally, it must be precise in the process of manufacture. And tolerances is required to control strictly.
