Main characteristics of alumina ceramic bushing

1. Outstanding wear resistance, over 276 times in comparison with stainless steel

2. Great mechanical properties, hardness, compressive and flexural strength are much higher stainless steel

3. Exceptional corrosion resistance, it can withstand various strong acid and alkali, like HF, H₂SO₄

4. Extraordinary electrical insulation, it always us in many high voltage, high-current application

Description of alumina ceramic bushing

Aluminum Oxide (Alumina, Al2O3) is the most commonly used industry ceramic material due to its versatile property characteristics and cost-effective advantage. As with the purity increases, both wear resistance and corrosion resistance also increases, so alumina are grouped together based on purity levels, including 75% alumina, 85% alumina, 90% alumina, 95% alumina, 99% alumina, 99.5% alumina, 99.8% alumina, 99.9% alumina.

Alumina ceramic tubes generally used as a kind of standard protection part, so our facility has many selections of stocks. Our vast, readily-available inventory allows us to supply our customer’s ceramic tube needs immediately, even for hard-to-find or specialty products. Aluminas are used in a variety of general-purpose applications, and their grade is chosen based on the application environment. Additionally, different purity alumina can be formulated in our factory if needed for more demand applications
