Fine polished 95% Alumina Parts Ceramic Eyelets for Wire Guide
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
Quality assurance:
1. High heat resistance : Alumina ceramic has excellent thermal stability,which means that it is widely used in areas where resistance to high temperatures is essential.
2. Good wear resistance : Alumina ceramic is the material of choice for alumina wear parts.
3. 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.
1) A variety of specifications available.
2) Satisfy various technical request
3) Lower medium spoilage
4) Good insulation performance and high temperature resistance
5) Stiffness texture
6) Used in all electric products and electric heating products
7) OEM, ODM and OBM are welcomed
