Aluminum is difficult to polish, as it is soft and the melting temperature is low. Too high temperatures will change the lattice structure of the aluminum, which can have impacts on further processing of the aluminum. Therefore different strategies and aluminas have to be applied. Almatis offers varius grades to fullfil the customers needs.
Alumina with top cut of 125 µm for heavy cutting compound and better pre-finishing compared to PSG 100.
Alumina with top cut of 90 µm for heavy cutting compound for good preperation of surface for the finishing process.
Ground alumina with top cut of 125 µm for cutting compounds.
Ground alumina with top cut of 40 µm for cutting compounds.
Unground alumina with top cut of 150 µm for heavy cutting compounds.
Ground Alumina with special controlled top cut at 45 µm / 325 mesh for cutting compounds.
Alumina with SSA of 4 m²/g and top cut of 200 µm for high cutting compounds.
