Detailed Product Description

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

1. Description:

To achieve the best possible part and to help aid in manufacturing and keep costs down, a wall thickness of no less than 10% of the O.D. should be maintained. However, we have successfully extruded parts with a wall thickness down to 5% of the O.D.

2. Feature Advantages:

1) Anti corrosion

2) Impact resistance

3) High stability

4) High welding sealing performance

5) Low thermal conductivity

6) Good wear resistance
