Product Description

 Alumina Ceramic

Alumina ceramic is the most mature of the engineering ceramics, offering excellent electrical

insulation properties together with high hardness and good wear resistance,but relatively low

strength and fracture toughness.Alumina ceramics are generally white but may also be pink or

ivory.The color is derived from either the sintering additives or impurities in the raw materials.

Features & Advantages of the industry ceramic:

1. High hardness.

2. High heat resistance : Alumina ceramic has execellent themal stability,which means that it is

widely used in areas where resistance to high temperatures is essential.

3. Good wear resistance : Alumina ceramic is the material of choice for alumina wear parts.

4. High electrical resistivity : Alumina is an electrically insulating material.

5. High corrosion resistance : It is insoluble in water and only slightly soluble in strong acid and

alkaline solutions. Good chemical stability of alumina leads to high corrosion resistance.


low loss at high frequency. Good insulating , high strength, , low dielectric constant, Great mechanical strength, high air tightness, high chemical stability, etc. We can produce all kinds of ceramic holders, ceramic support, ceramic tubes, ceramic pipe, ceramic ring, etc. Widely used in electronic components, electronic device and electric products. Our products meet the international standards.
