Brown Fused Alumina FeSi
Brown Fused Alumina FeSi
Description
Brown Fused Alumina FeSi is a by-product of normal alumina production.
It consists of one mineral and one metallic part. A tough and hard aluminum oxide with exclusive on silicon bonded iron fractions (FeSi). Non-corrosive but aggressive blasting agent.
Brown fused alumina FeSi is an alternative to iron-free mineral blasting media in the surface preparation of steel.
Various applications in steel work like rust removal, roughening and paint removal. Wear protection, heavy concrete.
Blasting systems
Pressure blast systems
Injection blast cabinets
