What's the difference between a hard alloy and a tungsten steel?
Tungsten steel: finished products contain tungsten 18% alloy steel, tungsten steel is hard alloy, also known as tungsten titanium alloy. The hardness is Vivtorinox 10K, second only to diamonds. Because of this, tungsten steel products (most of which are tungsten steel watches) are not easy to wear. Commonly used in lathe tools, percussion drill bits, glass cutter heads, ceramic tile cutting knives, solid and not afraid of annealing, but the quality is crisp.
Cemented carbide: in the field of powder metallurgy, hard alloys, also known as cermets, are made of metal carbides (WC, TaC, TiC, NbC, etc.) or metal oxides (such as Al2O3, ZrO2, etc.) as the primary components, to participate in a proper amount of metal powder (Co, Cr, Mo, Ni, Fe, etc.) by powder metallurgy, with some of the metal characteristics of the pottery. Porcelain. Cobalt (Co) is used in the alloy to play a bonding effect. In the process of sintering, it can encircle and bind the tungsten carbide (WC) powder tightly together. After cooling, it becomes a hard alloy. (the effect is equivalent to the cement in the concrete). Content usually: 3%--30% tungsten carbide (WC) is the primary component of the determination of some metal properties of the hard alloy or cermets, and the total component 70%---97% (component ratio) is widely used for wear resistant, high temperature resistance, corrosion resistance, and tools, tools, tools and tools.
Tungsten steel is attributed to hard alloy, but hard alloy is not determined to be tungsten steel. Today, customers in Taiwan and Southeast Asia prefer to use the word tungsten steel. If they talk with them carefully, they will find that most of them still refer to hard alloys.
