Features
[Brown alumina abrasive]
Abrasive made from alumina composed of bauxite and melted/reduced and coagulated in an electric furnace. It can be used in a wide range of fields because it features moderate toughness and a large grinding force.
[Main applications]
Base treatment prior to thermal spray Thermal spray removal processing Pre-paint base treatment Paint removal processing Deburring Emboss processing Grindstone raw materials Polishing paper raw materials

Features
[White alumina abrasive]
Highly pure alumina abrasive made of alumina refined using the Bayer process and melted in an electric furnace. It is purer than brown alumina and is therefore more versatile in a wide range of fields.
[Main applications]
Base treatment Lapping and blasting of metal, glass and crystal Floor materials Refractory raw materials Grindstone raw materials Polishing paper raw materials
Grain size distribution (coarse grain)
Grain size standard
Grain size | Test sieve that 100% of particles must pass through Stage 1: | Test sieve that may stop a set amount of particles and the resulting amount Stage 2: | Test sieve that must stop a set minimum amount of particles and the resulting amount Stage 3: | Two test sieves that, when combined, must stop a set minimum amount of particles and the resulting amount Stage 3 + Stage 4: | Test sieve that may allow a maximum of 3% of particles to pass through Stage 5 | ||||
