BROWN ALUMINUM OXIDE

Brown aluminum oxide is an abrasive sand belonging to the electrocorundum group. It is produced by melting calcined bauxite as a reduced solution at high temperatures in electric arc furnaces. It does not contain iron and has a high hardness, can withstand high pressure, and is resistant to abrasion.

Technical Specifications:

Hardness: High
Pressure and abrasion resistant structure
Grain structure: Angular — sharply fractured grains provide effective abrasion on the surface
Heavy surface treatments with appropriate granulometries

Advantages:

Fast surface removal on steel, iron and heavy metals
Roughening of hard surfaces and preparation before painting/coating
Repeated use and long life
Low metal contamination (ferrous free)

Areas of Use:

Heavy industry steel constructions
Surface preparation for drilling, pipes, tanks, docks and heavy building constructions
Post-welding surface cleaning and roughening
Heavy duty before painting and coating — surfaces requiring high strength
