Balanced Aluminium Oxide for Controlled Blasting
Pink fused alumina is engineered to deliver controlled cutting with enhanced durability. The addition of chromium oxide improves toughness while retaining the sharp grain structure associated with white alumina.
Suitable for ferrous and non-ferrous materials in wet or dry blasting systems.
Pink fused alumina is selected where process stability and abrasive longevity are required without sacrificing cutting performance.
