Aluminum oxide ceramic parts

Performance of alumina ceramics

High thermal conductivity, approximately 20-30 W/(m · K)

The coefficient of thermal expansion is close to that of metals, with a coefficient of thermal expansion of 6-8 × 10 ^ -6/K

Electrical resistivity of up to 10 ^ 14 Ω· cm or higher

The dielectric constant is usually between 8 and 10

Good compressive strength, usually above 2000 MPa

It is not easy to break when subjected to mechanical loads, and its bending strength can generally reach over 200 MPa

The hardness (Mohs hardness) is usually between 9 and 9.5
