S-U-Alustral is an especially pure, white precious corundum and does not provoke silicosis. It contains approximately 99.7% aluminium-oxide and is the hardest of all known currently existing precious corundums, contemporarily presenting the best splintered qualities, which guarantees a sharp surface of optimal abrasion. It does not contain contaminating particles. Its high quality standard is guaranteed by a network of intensive quality controls.
S-U-Alustral 50microns, extremely fine, for removal of investment material, ceramic alloy metal preparation, removal of surplus ceramic mass in metal-ceramic crowns.
S-U-Alustral 110microns, fine, for blasting off precious and non-precious metal alloys. Also for ceramic alloy metsl preparation.
S-U-Alustral 150microns, medium for blasting off precious and non-precious metal alloys. Also for ceramic alloy metsl preparation.
S-U-Alustral 250microns, coarse for blasting off Co=Cr-castings. Also for ceramic alloy metal preparation (non-precious alloys).
