Trade Name:
Starblast®
Description:
This product is a hard and unyielding abrasive, available in angular shapes. Starblast® is made by crushing and sintering bauxite ore. Bauxite is the main ore used to produce Aluminium and consists of 75% of aluminium oxide.
Application
Often used as to replace brown fused aluminium oxide, it can be used with conventional abrasive blasting equipment air-compressed pressure and suction jet-blasting equipment. Sintered bauxite is also used for the following applications: antiskid flooring, carving, etching, finishing, grinding, lapping, polishing, rock tumbling, lapidary, sandblasting, slurry mixes, surface preparation and tumbling.
Advantages
Often used to replace brown aluminium oxide.
