Product Description

White Metallized Alumina Based Ceramics Brazing With Metal For EV DC Contactor

 

1. Description:

Many people fail to realize that creating a product out of advanced technical ceramics is a demanding endeavor that requires considerably more work than metals or polymers. Every type of technical ceramic has specific thermal, mechanical, and electrical properties that can vary wildly depending on the material surrounding conditions. In fact, even the manufacturing process of the exact same type of technical ceramic material can drastically change its properties.

 

2. Feature Advantages:

1) High hardness and high density

2) Low thermal conductivity

3) Good insulation performance

4) High temperature resistance

5) A variety of specifications is available

6) Satisfy various technical requests
