Product Description

HV DC Brazing Aluminum Ceramics Relay Housing Technical Ceramic Metallized Parts

 

1. Description:

Brazing ceramic , it is important to consider the type of metal being used in the joint, as the coefficient of thermal expansion will become very important as the metal and ceramic contract and cool in different ways. Additionally, when designing a ceramic joint, it is important to try and keep the ceramic component in compression as ceramics perform best under this load.

 

2. Feature Advantages:

1) High elasticity modulus

2) High compressive strength.

3) Anti corrosion

4) Abrasion resistance

5) Impact resistance

6) High precision
