Alumina Seal Ceramic Rings / Industry Insulation Rings


1. Description:

Using ceramic materials to replace precious metals in swirl chamber diesel engines can further reduce cooling devices, so the overall cost is expected to be reduced. In the direct injection diesel engine, the high temperature resistance of ceramic materials is used to insert a ceramic block on the top of the piston, and the thermal efficiency, noise and emissions are all improved. The size and shape of the insert in the ceramic piston should be selected appropriately, otherwise due to the difference in the thermal expansion coefficient of the material, stress will be generated on the ceramic block, which will affect the service life of the piston; in addition, the ceramic fiber piston made of silicon nitride ceramic material, Because of its good wear resistance, it can prevent aluminum alloy pistons from "cold knocking and hot pulling" due to their large thermal expansion coefficient.

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
