AC6782 Monocrystalline Alumina Grain, Al2O3 Grain

Monocrystalline Aluminium Oxide Grain Description

Monocrystalline Aluminium Oxide Grain is an electro-fused abrasive manufactured by melting high-purity aluminium oxide with specific alloys, with each particle being a single crystal. This structure produces sharp, strong edges that enhance bonding and provide excellent cutting performance in bonded abrasives.

Monocrystalline aluminium oxide is environmentally friendly due to the absence of sulphur in the production process and is ideal for cool-cutting applications. It is used in industries such as aerospace, automotive, and cutting tools, and is preferred for precision grinding of high hard tool steels, general grinding, and cutting discs. With its high hardness and unique microstructure, it offers numerous durable cutting edges, leading to enhanced performance compared to white fused alumina or chromium-doped aluminium oxide. Monocrystalline aluminium oxide is increasingly becoming the preferred grain for thin high-performance discs, as it provides higher toughness and cutting speed.
