What is abrasive?
Abrasives are sharp, hard materials used to grind softer material surfaces. There are two types of abrasives: natural abrasives and artificial abrasives. According to the hardness, there are two categories: super-hard abrasives and ordinary abrasives. There is a wide range of abrasives, from softer household detergents and gem abrasives to the hardest material, diamond. Abrasive is an indispensable material for the manufacture of every precision product. Many natural abrasives have been replaced by artificial abrasives. Except for diamond, the properties of natural abrasives are not stable, but they still have their use value. Diamond is the abrasive with the highest hardness. It is produced mainly in South Africa, accounting for 95% of the world’s total output, and the rest are Brazil, Australia, Guyana and Venezuela. Industrial diamonds range from off-white to black, and can be crushed to make grinding wheels, belts, polishing wheels and abrasive powders.
