Product Description

Advanced Ceramic Housing Material Abrasion Resistant For Electric Vehicle Relay

 

1. Description:

High purity aluminas make for improved corrosion resistance due to lower impurity/silica content. Higher hardness, increased dielectric strength, and in some cases, superior flexural strength. Finer grain sizes also allow for smooth surface finishes. The grade of alumina is selected to best fit the application.

2. Feature Advantages:

1) Anti corrosion

2) Abrasion resistance

3) Impact resistance

4) Chemical inertness

5) High Fracture toughness

6) Stiffness texture
