Alumina polishing abrasives are generally used in polishing abrasive steel specimen

Alumina polishing abrasives are generally used in polishing abrasive steel specimen. But it should not be used for polishing aluminum and aluminum alloys, alumina abrasive easy because the aluminum surface dull and corrosion pits. Abrasive flap disc, Electric Power Tool Kits  one of the important properties is its hardness, it must be harder than the material to be processed,carbide drill bits used Mohs hardness was measured for various abrasives hardness. Another important performance abrasive toughness or volume strength. The blending amount of the raw material abrasive grinding wheel can be changed, purity, particle size and crystal structure to control the properties to suit various applications. Abrasive flap disc on a very wide range of industrial applications, especially in high-precision machining parts or low roughness or special hardware components, the abrasive and grinding tools is essential. In addition, the tool sharpening and hard material cutting, grinding wheel is an essential tool.
