Tungsten steel parts are not easy to wear

Because of this, tungsten steel products (commonly known as tungsten steel watches) have the characteristics of not being easily worn. Commonly used on lathe tools, impact drill bits, glass cutter bits, tile cutters, hard and not afraid of annealing, but brittle.
Cemented carbide: belongs to the category of powder metallurgy. Cemented carbide, also known as cermet, is based on metal carbides (WC, TaC, TiC, NbC, etc.) or metal oxides (such as Al2O3, ZrO2, etc.). (Co, Cr, Mo, Ni, Fe, etc.) Made by powder metallurgy, tungsten steel parts have ceramics with certain metal characteristics. Cobalt (Co) is used to play a bonding role in the alloy. During the sintering process, it can surround and tightly bond tungsten carbide (WC) powder. After cooling, it becomes hard. Alloy. (Effects equivalent to cement in concrete).
The content is usually: 3%-30% tungsten carbide (WC) is the main component that determines the properties of certain metals of this hard alloy or cermet, accounting for 70%-97% (weight ratio) of the total composition. It is widely used for wear resistance. , High temperature, corrosion resistance, harsh working environment parts or knives, tool bit.
