mineral specialist for steel, glass, wood, and plastics

KrampeHarex® fused alumina possesses exceptional cleaning properties and is available as brown and white fused alumina. Fused alumina is one of the electrocorundums. It is a non-silica, angular multi-use abrasive agent that is nonferrous, extremely hard, and abrasive. 

Due to its mass, and grinding and cleaning effects, fused alumina is used exclusively for compressed air blasting systems. The effect depends on the grain size – whether it’s something like descaling stainless steel, or wood and plastic processing.
