Product Description

Precision Customized U Shape 99.5% Al2O3 Ceramic Alumina Insulator for Machinery

Description of ceramic alumina isolator

Alumina ceramic is one of structural ceramics, with high insulation breakdown, high voltage resistance, high strength, good thermal conductivity, dielectric loss, and corrosion resistance. Due to alumina is more cost-effective among all technical ceramics, alumina ceramic insulators are commonly used in electronic ceramic substrates, high voltage/current electrical insulation, vacuum devices, devices porcelain, spark plugs and other products.
Our factory produces a selection of purity of alumina from 75% to 99.8%, all of the ceramic parts we supplied are with a dense body via dry pressing, hot pressing, ceramic injection molding, and ISO pressing. In order to achieve some special application for fitting, reducing the friction, increasing the insulation, we provide a serial of secondary processes after sintering, covering CNC machining, polishing, glazing and metallizing.
We manufacture a wide range of alumina ceramic rings, including ceramic tubes, ceramic rings, ceramic disc, ceramic rod, ceramic arms, ceramic wire guides. Whatever, its a prototyping case, or high volume demand, we believe we are able to provide you a desirable solution.
 
 

Prime features of ceramic alumina isolator

1. High electrical resistivity: used in all-electric products, electric heating products, and wear-resistant machinery parts.
2. Extreme high insulation, it can withstand 18KV at mm2 at least. With glazed treatment, it will increase the insulation.
3. They offer different grade dimensional accuracy per sintered only, precision machining
4. They are more cost-effective ceramic parts with equivalent performance among all other technical ceramics
5. High hardness, it is can be up to 1700 HV, and Super compressive strength up to 2240 Mpa
6. High heat resistance: Alumina ceramic parts offer excellent thermal stability, which means that it is widely used in areas where resistance to high temperatures is essential.
7. Good wear resistance: it is an ideal choice to wear parts in high abrasive industry
8. 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.
9. We support a variety of customized alumina ceramic parts base on customer's drawing, sample, or reference parameters

Packaging proposal and transportation solutions

1. We will keep the ceramic parts inside the inner package to be fixed without moving, then it will prevent them from collision each other, to avoid any cause any chippings during transportation.

2. In addition, the inside of the outer carton will be filled with sufficient protective kinds of stuff.
