Due to the increased productivity of wear-resistant components processed from tungsten steel hard alloys in many industrial fields, just a few examples include metal cutting, mining, mineral and civil engineering, agriculture, food processing, and textile industries. Although these industries are different, they all share a common point: the urgent need for resistance to impact, corrosion, and wear. This is why they use tungsten steel hard alloy wear-resistant parts.

Tungsten carbide mold is a series of synthetic materials composed of carbide particles bonded by binders. The proportion of carbides usually accounts for 70% -97% of the total weight of the composite, with an average grain size ranging from 0.2 to 14 μ m. Hard phase tungsten carbide (WC) and bonding phase cobalt (Co) form the basic structure of hard alloys, and other types of hard alloys have been developed based on this. In addition to pure tungsten carbide cobalt, it also includes hard alloys composed of titanium carbide (TiC), tantalum carbide (TaC), niobium carbide (NbC) and other materials in different proportions.

These carbides are miscible and contain a high proportion of tungsten carbide. Similarly, hard alloys can also be produced by using cobalt as the bonding phase or completely replacing it with other alloying elements such as nickel (Ni), chromium (Cr), molybdenum (Mo), iron (Fe), etc. Therefore, the three types of phases constitute hard alloys. In the metallurgical vocabulary, tungsten carbide phase is referred to as alpha phase, bonding phase (such as cobalt, nickel, etc.) is referred to as beta phase, and other individual or synthetic carbide phases (titanium carbide, tantalum carbide, niobium carbide, etc.) are referred to as alpha phase. Apart from its application in metal cutting, there is no clear classification of the application fields of hard alloys internationally. However, based on the grade of hard alloy, we can classify it into the following categories: composite materials such as WC Co alloys, corrosion-resistant alloys, cubic carbides, and DP alloys!
The main components of tungsten steel, such as WC particle size, TiC, TaC compound carbide composition and their addition amount, as well as the addition amount of bonding material Co, are various microstructures and compositions of hard alloys for cutting tools. By using them differently, they exhibit excellent wear resistance and toughness under various cutting conditions, and control the main component WC microstructure below 0.2-1 μ m. They are hard alloys that combine high strength and hardness.

In addition, it has excellent sharpness and the surface quality of the processed surface is also excellent. By flexibly utilizing these strengths, excellent performance can be achieved in various applications such as drill bits for printed circuit boards with a diameter of less than 0.1mm, end mill materials, thin edge cutting tools, precision molds, etc.
