Detailed Product Description

Alumina ceramic components / relay ceramic assemblies / ceramic - metal brazed contactor

 

1. Description:

Alumina ceramic (Aluminum Oxide or Al2O3) is an excellent electrical insulator and one of the most widely used advanced ceramic materials. In addition, it is extremely resistant to wear and corrosion and is an industrial ceramic that can only be formed by diamond grinding. The melting point is very high at 2,072°C, and it is very hard. Alumina components can be widely used in electronics, pump components and automotive sensors.

 

2. Feature Advantages:

1) Chemical inertness

2) Good wear resistance

3) High Fracture toughness

4) Good insulation performance

5) High temperature resistance
