Carbide Grinding Pot PM Sintered Parts
The finished product contains 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, tungsten steel products (tungsten steel watches are common) are not easy to be worn. It is often used on lathe tools, impact drill bits, glass cutter heads, and tile cutters. It is strong and not afraid of annealing, but brittle.

Tungsten steel
The finished product contains 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, tungsten steel products (tungsten steel watches are common) are not easy to be worn. It is often used on lathe tools, impact drill bits, glass cutter heads, and tile cutters. It is strong and not afraid of annealing, but brittle.
Carbide
Belonging to the field of powder metallurgy, cemented carbide, also known as cermet, is mainly composed of metal carbide (WC, TaC, TiC, NbC, etc.) or metal oxide (such as Al2O3, ZrO2, etc.), adding an appropriate amount of metal powder (Co, Cr, Mo, Ni, Fe, etc.) made by powder metallurgy method, ceramics with certain characteristics of metal. Cobalt (Co) is used to play a bonding effect in the alloy, that is, during the sintering process, it can surround and tightly bond the tungsten carbide (WC) powder together, and after cooling, it becomes a hard Alloy. (Effect equivalent to cement in concrete). Common 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. It is widely used for wear resistance, High-temperature resistance, corrosion resistance, and parts or knives with the harsh working environment, on the cutter head of the tool.
Tungsten steel belongs to cemented carbide, but cemented carbide is not necessarily tungsten steel. Now customers in Taiwan and Southeast Asian countries like to use the word tungsten steel. If you talk to them carefully, you will find that most of them still refer to hard alloys. alloy.
The difference between tungsten steel and cemented carbide
Also known as high-speed steel or tool steel, tungsten steel is smelted by adding tungsten iron into molten steel as a raw material for tungsten by steelmaking technology, also known as high-speed steel or tool steel, and its tungsten content is usually 15-25%; High-quality alloys are sintered with tungsten carbide as the main body and cobalt or other bonding metals by powder metallurgy technology, and the tungsten content is usually above 80%. Simply put, all things with a hardness exceeding HRC65 can be called cemented carbide as long as they are alloys. Tungsten steel is just a kind of cemented carbide with a hardness between HRC85 and 92, which is often used to make knives.
Qinhuangdao Zhongwei Precision Machine Parts Co., Ltd. mainly produces and develops cemented carbide products, including Carbide grinding pot PM sintered parts. With nearly 20 years of professional technology in the field, product quality is at the leading level in China.
