Product Description and Technical Data:
HardCut™ Silicon Carbide is an extremely hard, sharp and aggressive abrasive. It is formed inside electric furnaces, at a temperature of 2200 °C and produced from quartz and petroleum coke. it is chemically stable, has high resistance to oxidation and is also unaffected by acids and will only react to alkali at very high temperatures. As an abrasive, it is surpassed in hardness only by diamond, cubic boron nitride and boron carbide.
Being so hard HardCut™ is extremely fast cutting and can be used to clean and etch very hard surfaces that would otherwise not be possible with any other softer abrasives. Products manufactured from Tungsten Carbide may also be cleaned with HardCut™.
HardCut™ is harder and sharper than Aluminium Oxide but is more friable, therefore prone to breaking down at a faster rate.
HardCut™ is available in 2 types HardCut™ Type G and HardCut™ Type B.
Type G is the purest form of commercially available Silicon Carbide. It is used in many applications ranging from blast cleaning and glass etching, manufacture of bonded and coated abrasives through to refractory and ceramic applications. It is most suited for surface finishing non-ferrous materials such as cemented carbides, optical glass and ceramics.
Type B is used for surface finishing applications requiring a fast cutting action without leaving any ferrous residue on the blast surface. It is also extensively used in the manufacture of coated and bonded abrasives (e.g. sand paper, grinding stones and wheels), in refractory products and for glass etching.
