Product Description

Machined Rectangle Solid 99% 99.5% Alumina Ceramic Bar

Solid alumina ceramic bars offer excellent corrosion resistance, high insulation, exceptional mechanical strength. It will not effect and damage on the rod surface even if long-term sunshine, rainfall, humidity or Other weather factors , also ultraviolet rays can't change the rod surface quality. Meanwhile, the alumina bars have chemical stability, thermal stability, high mechanical strength, and hardness. These advantages make sure that the alumina bar is competent in severe working conditions.
Our company supplies a wide range of alumina bar are made out of high purity material range from 95% to 99.7%, 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
