99% Alumina Al2o3 Aluminium Oxide Ceramic Bushing

We are engaged in manufacturing, exporting and supplying an excellent quality 99% Alumina Ceramic Bushing to our valuable clients in Xiamen, Fujian, China. Alumina (aluminum oxide) is the most important, widely used and cost effective oxide ceramic material. The technical alumina ceramics contain at least 80% of aluminum oxide (AL2O3). Small amounts of silica (SiO2), magnesia (MgO) and zirconia (ZrO2) may be added to alumina ceramics. Addition of zirconia to alumina ceramic results in considerable increase of the material fracture toughness.

Typical Alumina characteristics include:
*High mechanical strength (flexural strength) and hardness;
*High wear resistance;
*High resistance to chemical attacks of strong acids and alkali even at high temperatures;
*High stiffness;
*Excellent insulating properties;
*Low coefficient of thermal expansion;
*Good fracture toughness;
*Good thermal conductivity;
*Good bio compatibility.

Application of Al2O3:
Aluminum ceramics are widely used in electronics and electrical engineering, metallurgical processes, chemical technologies, medical technologies, mechanical engineering, military equipment.
Aluminum ceramics are used for manufacturing insulators, capacitors, resistors, furnace tubes, sealing refractory parts, foundry shapes, wear pads, thermocouple protection tubes, cutting tools and polishing/grinding powders, ballistic armor and laboratory equipment.
