Grade: THM-F Hardness: 1780 Bending strength: 3000 Density: 14.8 Uses: suitable hardness> HRC55 machining hard materials, non-metallic material (nylon, plastic, fiberglass, etc.) when the dissolved carbon content exceeds a certain limit (the such as titanium carbide Ti ︰ C = 1 1:1), the lattice pattern will change, so that the original metal lattice into another form of metal lattice, then the Mesenchymal solid solution called filling compound. Metal carbides, especially Ⅳ B, Ⅴ B, Ⅵ B melting point metal carbide in the above 3273K, wherein the hafnium carbide, tantalum, respectively, 4160K and 4150K, is currently known the highest melting point of the material. Most carbide is very hard, and their hardness greater than 1800kg · mm2 (micro hardness is hardness represents one of the methods used for carbide and hard compounds, microhardness 1800kg · mm2 Mohs an equivalent a hardness of diamond 9). Many carbides difficult to decompose under high temperature, antioxidant capacity than its component metal strong. In all carbides TiC best thermal stability is a very important metal carbide. However, in an oxidizing atmosphere, all the carbides are easily oxidized at high temperatures, can be said that this is a major weakness carbide.
