Paduan keras memiliki serangkaian kinerja yang baik, seperti tingkat kekerasan tinggi, daya tahan, kelenturan yang baik, tahan panas, dan tahan korosif, terutama tingkat kekerasannya yang tinggi dan tahan banting, bahkan pada suhu 500°C, namun tetap memiliki tingkat kekerasan yang tinggi pada 1.000°C.
Cemented carbide, also known as tungsten steel, is made of high quality tungsten carbide + cobalt powder by pressing and sintering after the mixture of formula ratio, with high hardness, high strength, high wear resistance, and high elastic modulus, belonging to the powder metallurgy industry. As the teeth of modern industry, cemented carbide cutting tools play a fundamental role in promoting the development of the manufacturing industry.
Paduan keras dapat dibagi menjadi paduan keras biasa berdasarkan butiran kristal, paduan kristal halus, dan sub-kristal ultra-kristal. Berdasarkan bahan kimia utama dapat dibagi menjadi paduan keras berbahan dasar karbonasi dan berbahan dasar titanium berkarbonasi.
Titanium carbide base cemented carbide is Tic as the main component, commonly used metal bonding Mo and Ni. Cemented carbide has a high hardness (86 ~ 93HRA, equivalent to 69 ~ 81HRC), second only to diamond, and good thermal hardness (up to 900 ~ 1000℃, maintaining 60HRC). High bending strength (MPa5100), good impact toughness and high corrosion resistance, chemical inertness, and other properties not found in ordinary alloy blades.
