Alumina ceramic washer

1. Description

Alumina ceramic product is produced by alumina as the main material, through the forming, high temperature sintering has good heat resistance, high performance, good compression wear-resisting performance , high insulating strength, high mechanical strength, thermal expansion coefficient little etc
Widely used in electronics, electrical equipment, instrument and apparatus, household appliances, electric vacuum device, communication equipment, temperature control switch, high-grade ceramic valve, faucet move sliding-vane, and other industries for precision components use and in the media with grinding and polishing

Specification:

1.This kind of ceramic washer is made of alumium oxide ceramics in purity of 95% ~99.8% . We have other selective advance fine ceramic material for option, like zirconia ceramic washers, silicon carbide washers, silicon nitride washers, titanium oxide ceramic washer and so on.

2. We have state -of - the - art manufacturing processes, it helps us to achieve very high and tight dimensional tolerance to be 0.005mm via CNC machining, high precison grinding, high precision lapping and laser cutting.

3. The facility has a complete of comprehensive surface finish equipment, like polishing and glazing. The best roughess of alumina ceramic wahser can be Ra0.025.

4.All these engineering ceramic parts are with quality guaranteed before shipping, especially the critical dimensions will be make fully checking.
