Engineering ceramics are those which have been specially produced to create ceramic components to provide solutions for engineering conditions with specialist requirements. The thermal stability, wear-resistance and resistance to corrosion of ceramic components make the application of ceramic the ideal choice for many industrial areas.Ceramic components can provide considerable lifetime increases over conventional metal components.If you are looking for a material,that has a longer working life and can stand up to wear, corrosion and high temperature,the engineering ceramic is the answer.
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.

3.Features & Advantages
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.
