Description
Aluminum Nitride Ceramic Ring is a high-performance advanced ceramic component manufactured from high-purity aluminum nitride ceramic. With a purity of over 99%, density of ≥3.30 g/cm³, Vickers hardness of HV0.5≥1200, bending strength of ≥350 MPa, and thermal conductivity of 170–200 W/(m·K), it is designed for demanding applications requiring excellent wear resistance, mechanical strength, thermal conductivity, and dimensional stability.
Aluminum nitride ceramic combines high thermal conductivity with excellent electrical insulation, making it different from many conventional wear-resistant ceramic materials. Its low thermal expansion and good thermal stability allow the material to maintain reliable performance under temperature changes and elevated-temperature operating conditions.
The high hardness and bending strength of the material make AlN ceramic rings suitable for mechanical contact and wear-resistant applications. They can be used as mechanical seal rings, bearing components, and other precision ceramic parts where resistance to friction, dimensional stability, and long-term service performance are required.
In addition, the excellent thermal conductivity of aluminum nitride makes it particularly suitable for semiconductor substrates and packaging materials. Customized AlN rings and other ceramic components can be manufactured according to customer drawings, dimensions, tolerances, surface finish requirements, and application conditions.
