Description

Alumina Seal Ceramic Rings / Industry Insulation Rings

1. Description:

Applications of Ceramic Seal Rings:

Aerospace applications: high resistance to thermal and mechanical shock is necessary for many aerospace applications. Alumina ceramic components are ideally suited for aerospace applications, due to their ability to withstand the high temperatures, vibration and mechanical shock typically found in aircraft engines and other high-stress locations. Ceramic Seal Ring is commonly found in seals for gas turbine engine thermocouples, fuel line assemblies, and fire detection system terminations.

2. Feature Advantages:

1) Refractory, High Temperature Resistance, Maximum Used Temperature: 1800 ºC (3272ºF)
2) Hardness Strength, Wear Resistance Up To Mohz 9.0 ; HRA 80-90
3) High Voltage, Good Insulation Performance ,Electrical Resistivity Up To 10∧14 Ohm.Cm
4) High Polished Surface Up To Rz0.8(Ra0.1)
5) Superior Mechanical Strength, MAX 10 MPa.m1/2 Fracture toughness
6) Pressure Resistance, Max 2300MPa compressive strength
7) Anti-High Corrosion Resistance, Such As Acid Alkali Resistance
8) Long Service Life
9) Other excellent property
