Description

Custom Alumina Ceramic Rings / Sealed Ceramic Connectors for Battery

1. Description:

Alumina ceramic ring — Alumina ceramics is a ceramic material with Al2O3 as the main crystal phase. Antaeus can produce ceramic products with an alumina content of 95% to 99.8%. The alumina has a compact structure, low activity, and high-temperature stability. The electrical properties are the best, with good mechanical properties, with a Mohs hardness of 9.

2. Feature Advantages:

1) Abrasion resistance

2) Impact resistance

3) High stability

4) Good advanced ceramic materials

5) Good wear resistance

6) A variety of specifications is available
