Carbides are combinations of special metals and carbon to form very hard materials greater than that of hardened steel. They are therefore used in applications requiring extreme strength such as machine tool bits, drilling and mining operations. The mechanical properties of carbides are determined in terms of Hardness at varying temperatures, Hardness measured at room temperatures, Compression strength in megapascals, Transverse rapture force in megapascals and Elasticity.


The special combination of physical and structural properties of carbides gives them special industrial uses. These include resistance to abrasion which is very high and they easily outlast hard steel grades, Resistance to deflection: Compared to steel bars of the same grades, carbides have an elasticity modulus of up to three times more which equals to one third deflection compared to the steel bars. These are properties which make these carbide chemicals very effective in extreme temperature and pressure conditions such as in drilling and machine tool bits. Carbide balls are also used as milling agents due to their hardness in Attritor mills.
