Main characteristics of the alumina ceramic standoff

1. High hardness, it is can be up to 1700 HV, and Super compressive strength up to 2240 Mpa
2. 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.
3. Good wear resistance: it is an ideal  choice  to wear parts in high abrasive industry
4. High electrical resistivity: used in all-electric products, electric heating products, and wear-resistant machinery parts.
5. 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.
6. We support a variety of customized alumina ceramic parts base on customer's drawing, sample, or reference parameters

 

Description of alumina ceramic standoff

Our facility manufactures many different sizes of alumina ceramic standoffs. Alumina ceramic standoffs are very stable under high temperatures, as they have outstanding dielectric properties, chemical erosion resistance and high wear and abrasion resistance.
In addition, they have excellent mechanical strength which makes these components last a great deal longer than those made from non-ceramic materials. Our Alumina & Steatite Standoffs are economical and practical.
Outside diameter surfaces can be glazed or unglazed. All Insulators have radii on all corners. Custom sizes can be produced by request. 
Besides ceramic standoff, 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.
 

 

Application of alumina ceramic parts:

Alumina ceramic parts are widely used in the electronic, electrical, machinery, chemistry, ceramic seal, mineral, new energy, military, aerospace, almost all modern industries.

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.
