Usage

Brown Corundum

(A)

High hardness and toughness

It can be used for grinding medium and high tensile strength metal such as ordinary carbon, steel, alloy steels, malleable cast iron, hard bronze etc.

White

Corundum

(WA)

Its hardness is higher than that of the A. Grains are easily broken. The edges of the grains are sharp with excellent cutting performance small quantity is produced.

It can be used for grinding harder material and metals sensitive to heat such as chilled steel, high carbon steel ordinary high speed steel, alloy steel .it is specially suitable for the grinding and forming grinding instruments, cutting tools, gears threads, thin wall parts, etc

Pink Corundum

(PA)

The hardness is close to WA, but the hardness is higher. The grains are sharp. It is much durable,

Used for the grinding of the chilled steel, cutting tools and work-pieces of alloy steel as well as the precision grinding of the measuring tools and parts of the instruments.

Mixture of A and WA

(A/WA)

It possesses the advantage of both A and WA

It is suitable for the grinding of nodular, cast iron crank shaft, cam shafts and other work-pieces.

Green Silicon

Carbide (GC)

With high hardness and brittle. Its grain edges are sharp， and it is of excellent capacity of the heat –transmission.

It is suitable for the grinding of the cutting tools and work-pieces of hard alloy, and non-ferrous metal and non-metal materials

Black Silicon

Carbide (C)

With high hardness and brittle. Its grain edges are sharp and it is of certain capacity of the heat –transmission.

It is suitable for the grinding of non-ferrous and non–metal materials.
