The Difference Between Carbide And Tungsten Steel
1. Tungsten steel: the finished products contain about 18% tungsten alloy steel, tungsten steel belongs to the hard alloy, also known as tungsten titanium alloy. The hardness is 10K, second only to diamond. Because of this, tungsten steel commodity (see more tungsten steel watch), with the characteristics of not easy to be worn. It is often used on lathe tools, percussion drill bits, glass cutting head, and ceramic tile cutting knife.

2. Carbide: to cemented carbide powder metallurgy field and metal-ceramic metal carbide (WC, TaC TiC, NBC, etc.) or metal oxide (such as Al2O3, ZrO2, etc) as the primary ingredients, in just the right amount of metal powder (Co, Cr, Mo, Ni, Fe) made by powder metallurgy method, has the qualities of some metal ceramics. Cobalt (Co) is used to bond the alloy. During sintering, it encloses tungsten carbide (WC) powder and binds it tightly together. General content: 3%--30% tungsten carbide (WC) is the primary component of some metallic properties of this carbide or cermet, 70%-- 97% (component ratio) is widely used for wear resistance, high-temperature resistance, corrosion resistance, harsh working conditions of parts or tool, tool head. Tungsten steel is attributed to the hard alloy, but the hard alloy is tungsten steel is different, nowadays the customer of Taiwan and southeast Asia country likes to use tungsten steel this word, if talk with them carefully thorough, can discover, the majority still is to point to hard alloy.
The difference between tungsten steel and cemented carbide lies in: also known as high-speed steel or tool steel, tungsten steel is made by melting tungsten and iron in steel with steelmaking technology, also known as high-speed steel or tool steel, its tungsten content is usually 15-25%. The hard alloy is made of tungsten carbide sintered with cobalt or other bonding metals by powder metallurgy technology, and its tungsten content is usually above 80%.
The brief said that all hardness beyond HRC65 things as long as the alloy can be called hard alloy, tungsten steel is just a hardness of hard alloy between HRC85 to 92, often used to do non-standard tools, measuring tools.
