Product Description

Diamond Polished Wear Resistance Long Al2O3 Alumina Ceramic Rod for Industrial

Prime features of the ceramic alumina rods

1. High precision dimensional tolerance with diamond polished surface quality

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

3. Extreme wear and abrasion resistance., over 276 times in comparison with 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. Extreme high-temperature stability under reducing, inert, and high-vacuum conditions under high temperature up to 1800°C.

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

Description of ceramic alumina rods

Alumina solid ceramic rod gets an excellent corrosion resistance, high insulation, exceptional mechanical strength. Long-term sunshine, rainfall, humidity or other weather factors do little effect and damage on the rod surface, not even ultraviolet rays can change the rod surface quality. Meanwhile, the alumina rod has acid and alkali stability, thermal stability, high machining strength, and hardness. These advantages make sure that the alumina rod is competent in severe operating conditions.
Our company supplies a great of dense alumina rod made of high purity material, of what the performance and parameter reach to the international level, we also supply polishing and glazing treatment on the rod surface, which make rods smooth and enhance its performance in the application.

1. Different diameter and length will be with different tolerance
2. All long ceramic rods can be cut per customized length
3. Other ceramic solid rods with different diameter are available

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.
