Brown Fused Alumina
High hardness and toughness.
For medium and high tensile strength metal such as ordinary carbon steel , alloy steel , malleable cast iron, hard bronze, etc.
White Fused Alumina
White,higher hardness than that of A. Easily broken, sharp edges,excellent cutting performance, low level of grinding heat.
For harder material and metals sensitive to heat such as chilled steel, high carbon steel . ordinary high speed steel, alloy steel. Mainly suitable for grinding and forming of instruments, cutting tools , mouldings , gears, threads, thin-shell parts, etc.
Pink Fused Alumina
Pink,similar hardness with WA, higher toughness than WA, sharp edges ,excellent durability.
For chilled steel, cutting tools and workpiece of alloy steel as well as precision grinding of measuring tools and parts of instruments and apparatus, etc.
Monocrysta Line Fused Alumina
Light yellow or yellow,higher hardness and toughness than WA. Grains are ball-shaped single crystals with outstanding multicomer edges and strong impact strength.
For stainless steel ,high vanadium-high speed steel and workpiece in high toughness and being easily-deformed and burnt.
Microcrysta Fused Alumina
Blue, grains are composed of small crystals .High toughness,strong shrength,excellent self-sharpening performance.
For ball-bearings , stainless steel and special nodular cast iron as well as forming, grinding, infeeding grinding and precision grinding, etc.
Mixture Of A And WA
Advantages of A and WA.
For nodular cast iron crankshaft, cam shafts, etc.
Green Silicon Carbide

Good heat resistance,water-proof, large porosity, elasticity differenc.
Extensive application, suitable for forming grinding, gear grinding, screw thread grinding V<35m/s.
High strength, definite elasticity,impact resistance,poor solidity, heat tolerance, small, porosity.
Suitable for high speed grinding v>50m/s. Thin disc wheel for step grinding.
Higher strength and elasticity, less pores and poor heat tolerance.
Suitable for grinding races/rollers of bearings and ideally used as regulating wheels in centerless grinding ,thin cutting wheels and polishing wheels.
Good toughness and forming, strong strength, poor self-sharping.
Suitable to be made to diamond abrasive tools.
