What is the difference between hard alloy and steel
Tungsten carbide hard alloy belongs to, but not necessarily tungsten steel, now Taiwan and Southeast Asian countries customers love to use the word if they talk with tungsten, carefully into the deep, we will find that most of us. Or to the hard alloy and tungsten steel the difference is: also called hard alloy tool steel or high speed steel, tungsten steel is the raw material for smelting molten steel in steelmaking process for adding tungsten as a, also called high speed steel or tool steel, the tungsten content in 15-25%, The hard alloy is used; powder metallurgy of tungsten carbide as subject and cobalt or other metal bonded together and sintered, the tungsten content of more than 80% in general. Simply put all the hardness more than HRC65 as long as things go can be called cemented carbide alloyIs a kind of tungsten carbide hardness between HRC85 and 92, is often used as a knife
Cobalt (Co) is used in bonding in the alloy, is in the process of sintering, it can make the tungsten carbide (WC) powder and tightly surrounded Bonded together, after cooling, became hard alloy. (equivalent to the cement content). Usually: 3%--30% tungsten carbide (WC) is the main component of some metal properties of the hard alloy or cermet, the total composition of 70%---97% (weight ratio) is widely used in wear-resistant, high temperature resistance, resistance corrosion, bad working environment of the parts or tool, cutter tools.
Products: tungsten steel containing approximately 18% tungsten alloy steel, tungsten steel belongs to hard alloy, also called tungsten titanium alloy. The hardness for the Vivtorinox 10K, second only to diamond. Because of this, tungsten steel products (a common watch), has the characteristics of not easy to be worn. Commonly used in lathe tool, drill, impact drill glass knife head, tile cutter, hard annealing, but brittle. Hard alloy: powder metallurgy hard alloy belongs to the category of metal ceramic is also known as metal carbides (WC, TaC, TiC, NbC, etc.) or metal oxide (such as Al2O3, ZrO2 etc.) as the main ingredient, adding proper amount of metal powder (Co Cr, Mo, Fe, Ni, etc.) made by powder metallurgy method, has some characteristics of metal ceramic.
