High Voltage Relay Metallized Brazing Alumina Ceramics 3.9g/Cm3 For EV Car

High Voltage Relay Metallized Brazing Alumina Ceramics 3.9g/Cm3 For EV Car


1. Description:

Technical ceramics tend to be excellent electric insulators (high dielectric strength). They are especially useful in high-temperature applications where other materials’ mechanical & thermal properties tend to degrade. Some ceramics have low electrical loss & high dielectric permittivity; these are typically used in electronic applications like capacitors and resonators. Additionally, the ability to combine an insulator with a structural component has lead to many product innovations.


2. Feature Advantages:

1) High hardness and high density

2) Low thermal conductivity

3) High welding sealing performance

4) Good insulation performance

5) High temperature resistance

6) Satisfy various technical requests
