PRODUCT DETAILS
Product Description
Alumina ceramic:
Alumina ceramic rings have high hardness, high wear resistance, excellent electrical insulation and chemical stability, good heat resistance.
Alumina ceramic ring:
It can be produced by hot pressing, dry pressing, isostatic pressing, extrusion and other production processes
It is specifically used for high temperature and high pressure insulation parts,
Advantages of alumina rings :
1). Excellent insulation ,security , long working life . 2). Precise grinding and polishing. 3). Excellent heat radiation, small size ,more environmental and energy-efficient . 4). good thermal conductivity
Precision ceramic rings:
It is widely used mainly used in semiconductors, machinery, electrical appliances , petrochemical,textile and other industries.
