Prime features of alumina ceramic pin

1. High precision dimensional tolerance with diamond polished surface quality

2. Extreme wear and abrasion resistance., over 276 times in comparison with stainless steel

3. Great mechanical properties, hardness, compressive and flexural strength are much higher stainless steel

4. Extraordinary electrical insulation, it always us in many high voltage, high-current application

5. Chemical corrosion resistance under high temperature, even if with strong acid or alkali

6. Protective atmospheres or high vacuum at high-temperature to eliminate contamination or impurity.

7. Low material cost in high-level applications than other technical ceramics

8. Extreme high-temperature stability under reducing, inert, and high-vacuum conditions under high temperature up to 1800°C.

Description of alumina ceramic pin

Alumina is a most seasoned of the advanced ceramics, offering excellent electrical insulation properties together with high hardness and superb wear resistance but relatively low strength and fracture toughness. Moreover, high purity alumina ceramics are ideal for environments where resistance to wear and corrosive substances are required. Alumina ceramic has excellent thermal stability, which means that it is widely used in areas where resistance to high temperatures is essential.

We offer a selection of shaping methods to make the alumina ceramic pin which depends on the size, the real application. Like small ceramic pins, it's regularly shaped via dry pressed, hot pressed and ceramic injection molding, like big size ceramic pins, it's commonly formed by ISO pressed and extrued.

In addition, all these ceramic pins can be machined further after sintering, like precision grinding, lapping, polishing and so on.
