Polishing abrasive

Folding diamond
Extremely high hardness, sharp sharp particles, for different hardness of the material has a good grinding effect, for the existence of the difference between the hardness of different phases of the alloy sample polishing effect is good. In addition, diamond polishing abrasive long life, high cutting ability, and thus less abrasive consumption, but also can make the test sample surface does not produce distortion of the layer.
Folding aluminum oxide
The hardness is high, and the material is generally not chemical reaction. Alumina polishing abrasive is generally used in the general steel sample polishing abrasive. But it should not be used for polishing of aluminum and alumina abrasive Aluminum Alloy, because it is easy to make aluminum surface is dark and corrosion pit.
Folding chromium oxide
The polishing ability is weaker than that of alumina, which can be used as the final polishing of the steel sample.
Iron oxide
Aurora bright surface can be obtained, but also easy to produce deformation disruption layer and non metallic inclusions from the metal sample matrix drag a rarely used.
Magnesium Oxide folding
The hardness is relatively low, the particle is very thin, with a sharp shape and a good grinding edge. It is suitable for the final polishing of aluminum, magnesium and other non ferrous metals and alloys. It of drag of nonmetallic inclusions of steel samples in the effect is small. Therefore, it is especially suitable for finishing on inclusion test and cast iron graphite specimens is particularly advantageous.
