Alumina ceramic (95% 99% 99.7% Al2O3)

Alumina (Al₂O₃) features high hardness, excellent wear resistance, high melting point, good chemical stability, electrical insulation and thermal stability. Common parameters include high compressive strength, low dielectric loss and controllable porosity. It is widely used in ceramic substrates, wear parts, cutting tools, electronic insulators, refractory materials and biomedical components.
