ALUMINIUM OXIDE
Aluminium Oxide is an angular and durable blasting abrasive that can be recycled many times. Widely accepted in applications in which high surface roughness requirements exist it is an extremely attractive option due its low cost, longevity and hardness. Harder than most other commonly used blasting materials, aluminium oxide grit penetrates and cuts even the hardest materials and sintered carbide. Approximately 50% lighter than metallic media, aluminium oxide abrasive has twice as many particles per kg. The fast-cutting action minimizes damage to thinner materials by eliminating surface stresses caused by heavier and slower cutting media.
