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 ensure the alumina rod is competent in severe operating conditions.
Our company supplies a great of dense alumina rod made of high purity material, of which 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.
