Fine Precision Polishing Industrial 99% Alumina Ceramic rod for sale
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
High performance ceramics offer significant advantages over metals and plastics. They have in general good mechanical properties and are particularly resistant to compression. Some ceramics are very resistant to wear and friction. They also show relatively low friction coefficient and good toughness. It is also possible to achieve very good surface finishes that ensure leak tightness. Ceramics are all the more relevant when the application is associated with thermal stresses, abrasive particles or food compatibility. And ceramics are inert mateials that are resistant to many gases and acids.
This material has very high hardness, very high stiffness, very good corrosion resistance to chemicals at high temperature, and very high refractoriness or use temperature.
