Abrasive types – codes (key)10 rows

Code	Abrasive	Application
5A	Regular grey aluminium oxide	tough and resistant; general use on iron and low-alloy steels
6A	Mixed grey + white aluminium oxide	softer than 5A; surface grinding of medium-hardness steels or cylindrical grinding of high-hardness steels and engineering cast irons
10A-7A-8A	High-grade 99% Al2O3 aluminium oxide, white (10A), blue (7A), brick red (8A)	general precision grinding
9A	High-grade pink aluminium oxide	precision grinding; tougher than 10A, for alloy steels
13A	High-grade ruby aluminium oxide	high cutting ability; hardened steels with a high degree of hardness
11A	Monocrystalline aluminium oxide	precision grinding and sharpening of high-alloy, high-hardness, heat-sensitive steels
5C	Grey silicon carbide	deburring of hard cast iron, grinding of spheroidal graphite cast iron and non-ferrous materials (brass, rubber, stone, plastic, etc.)
8C	Green silicon carbide	very hard, friable and sharp; cemented carbide, ceramics, glass, bronze and aluminium
0A	Zirconia	resin bond wheels only; deburring of cast iron and steels
MC	SG microcrystalline aluminium oxide	blended with 7A or 11A in various percentages, for high-performance grinding
