Product Description

High Precision Wear Resistant 99.5% AL2O3 Alumina Ceramic Plate

Our alumina plates are manufactured to high standards, primarily using 95% and 99.7% Al2O3. With densities ranging from 3.6g/cm³ to 3.9g/cm³, these products are engineered for durability. We offer casting plates, dry pressing plates, and ISO pressing plates to suit various industrial applications.

Key Advantages

High Purity: Available in 95% Al2O3 (3.6g/cm³) and 99.7% Al2O3 (3.9g/cm³).
Tight Tolerance: Precision machined to tolerances as low as +/-0.002mm.
Superior Surface: Surface roughness can reach up to Ra0.1um.
Strict Quality Control: Every single plate is individually inspected before shipment.
