Customized Electrical insulation Alumina Ceramic Products Manufacturing

Description of alumina ceramic products

Alumina (Al2O3) possesses high-temperature resistance, excellent electrical insulation together with good wear resistance and high hardness, that's why alumina ceramic parts are commonly used as a kind of insulating, heat resistance and anti-chemical engineering and structural ceramic components, including high voltage ceramic holder, ceramic electrical insulator ceramic parts in high-temperature furnace, ceramic seal disc in pump and so on.
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.

Main characteristics of the alumina ceramic products

1. With compact and consistent size via fine grinding, lapping, CNC machining
2. Smooth surface free of cracks, impurity, or diamond polished to be mirror surface
3. High hardness, it is can be up to 1700 HV, and Super compressive strength up to 2240 Mpa
4. 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.
5. High electrical resistivity: used in all-electric products, electric heating products, and wear-resistant machinery parts.
6. Good wear resistance: it is an ideal choice to wear parts in high abrasive industry
7. 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.
8. Alumina ceramic components have an outstanding cost-effective advantage with equivalent performance than other technical ceramics
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.
