Metal Pre-polish

Before the finishing step of the polishing process the surfaces have to be prepared. Therefore a pre-polishing step is used, for which high cutting compounds are used. A combination of high cutting and good polishing results, which can be achieved with Almatis aluminas can save time and money in the following finishing step.

Hard

A 10 5 µm

Alumina with top cut of 150 µm for very heavy cutting compounds.

A 10 -325

Ground alumina with top cut of 45 µm / 325 mesh for cutting compounds.

PSG 100

Alumina with top cut of 200 µm for very heavy cutting compounds.

PSG 125

Alumina with top cut of 125 µm for heavy cutting compound and better pre-finishing compared to PSG 100.

PSG 140

Alumina with top cut of 90 µm for heavy cutting compound for good preperation of surface for the finishing process.

PSG 150

Ground alumina with top cut of 125 µm for cutting compounds.
