Alumina abrasive material 'A' suitable for precision grinding stones and polishing cloths for ultra-finish.
Maintains stable polishing performance! Suitable for materials such as precision grinding stones for ultra-finish and ultra-finish polishing cloths.
"A" is a widely known abrasive also referred to as Alundum. It is composed of corundum crystals with an Al2O3 purity of over 90%, obtained by melting bauxite in an electric furnace at a high temperature of 2000°C. A characteristic feature is that a few percent of titanium is solid-solved to enhance toughness (resistance to fracture) as an abrasive grain. As a result, the product possesses high toughness among polishing micro-powders and is consistently adjusted to a uniform particle size distribution, leading to high polishing efficiency and scratch-free polished surfaces, while maintaining stable polishing performance. [Features] - A few percent of titanium is solid-solved to improve toughness (resistance to fracture) - Possesses high toughness among polishing micro-powders - Maintains stable polishing performance - Suitable for materials such as precision grinding wheels for ultra-finish and ultra-finish polishing cloths - Also ideal for precision lapping of various glass types, including cathode ray tubes, and soft metals *For more details, please refer to the PDF document or feel free to contact us.
