Why are products made of tungsten steel not easy to be worn

       Under normal circumstances, parts made of tungsten steel contain about 18% tungsten alloy steel, and tungsten steel belongs to cemented carbide, also known as tungsten-titanium alloy. The hardness is Vickers 10K, second only to diamond.



Because of this, products made of tungsten steel (commonly include tungsten steel watches) are not easy to be worn. It is commonly used in lathe tools, impact drill bits, glass cutter bits, and tile cutters in industry. It is hard and not afraid of annealing, but it is brittle.



Cemented carbide belongs to the category of powder metallurgy, also known as cermet, which is mainly composed of metal carbides (WC, TaC, TiC, NbC, etc.) or metal oxides (such as Al2O3, ZrO2, etc.), adding an appropriate amount of metal powder (Co, Cr, Mo, Ni, Fe, etc.) are made by powder metallurgy, and tungsten steel parts are ceramics with certain characteristics of metals. Cobalt (Co) is used for bonding in alloys, that is, in the process of sintering, it can surround and tightly bond tungsten carbide (WC) powder together. After cooling, it becomes hard. alloy. (The role is equivalent to cement in concrete).



Usual content: 3%-30% Tungsten carbide (WC) is the main component that determines some metal properties of this cemented carbide or cermet, accounting for 70%-97% (weight ratio) of the total composition, widely used for wear resistance, high temperature resistance , Corrosion-resistant, parts or tools with harsh working conditions, on the tool head.



Tungsten steel belongs to cemented carbide, but cemented carbide is not necessarily tungsten steel. Now Taiwan and Southeast Asian countries like to use the word tungsten steel. If you talk with them carefully, you will find that most of the tungsten steel parts still refer to our hard alloys. Alloy
