Polishing abrasive

Folding diamonds

High hardness, sharp and sharp grain shape, for different hardness of the material has a very good grinding effect, for the existence of different soft and hard phase difference between the different phase of the alloy sample polishing effect is better. In addition, the diamond polishing abrasive grinding long life, high cutting capacity, and thus less abrasive consumption, but also can make the surface of the sample does not produce deformation damage layer.

Folding alumina

High hardness, and polished material is generally not a chemical reaction. Alumina Polishing Abrasives are commonly used for abrasive abrasives in steel samples. But it should not be used to polish aluminum and aluminum alloy, because the alumina abrasive easy to make the aluminum surface dull and produce corrosion pits.

Folding chrome oxide

The polishing capacity is weaker than that of alumina and can be used as a final finish for steel samples.

Folding iron oxide

A very bright surface can be obtained, but at the same time prone to deformation disturbing layer, and will be non-metallic inclusions from the sample metal matrix dragged out, use very little.

Folding magnesia

Low hardness, fine particles, with a sharp shape and a good grinding edge. It is more suitable for aluminum, magnesium and other non-ferrous metals and alloy samples of the final polishing. It is particularly small for the non-metallic inclusions in steel samples and is therefore particularly suitable for inclusions and is particularly advantageous for polished graphite samples.
