3. High precision tighten dimensional tolerance with diamond-like surface quality
4. Extraordinary electrical insulation, it always used in many high voltages, high-current application
5. Chemical stability, it can be used under high-temperature strong acid or alkali
6. Protective atmospheres or high vacuum at high-temperature to eliminate contamination or impurity
Description of high-purity alumina ceramic rods
Al2O3 ceramic rods have excellent corrosion resistance, high insulation, and exceptional mechanical strength. Long-term sunshine, rainfall, humidity, or other weather factors do little effect and damage 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.| S/N | Material | Diameter (mm) |
