Product Details
White High Mechanical Strength Alumina Ceramic Disc High Wear
Resistance
1. Description
Alumina ceramic is widely used in many fields. Because of its great
performance, it is more and more used in curent society, alumina
ceramic substrate can meet the requirement of daily using and
specifical features.
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 ceramic is generally white but may
also be pink or ivory. The color is derived from either the
sintering additives or impurities in the raw materials.
2. Main Features
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.
