Product Description

Alumina ceramic, or aluminum oxide (Al₂O₃), is an industrial ceramic material known for its exceptional hardness, wear resistance, and durability. These properties make it suitable for applications requiring diamond grinding for shaping. Alumina ceramics are manufactured from either white granular material or a fine silky dense powder refined from bauxite.
