The wear-resistant alumina ceramic is made of high-purity ultra-fine α-alumina powder and optimized by high-temperature sintering. It has excellent anti-wear and anti-corrosion properties. After engineering design, Qishuai can manufacture various kinds of materials. Abrasion-resistant alumina products with different geometrical shapes and complex shapes, combined with appropriate linkage methods, solve various wear problems in many industrial applications.
It has been determined by the Shanghai Institute of Ceramics of the Chinese Academy of Sciences to have a Rockwell hardness of HRA80-90, which is second only to diamond, far exceeding the wear resistance of wear-resistant steel and stainless steel.
2. Excellent wear resistance
According to the Institute of Powder Metallurgy, Central South University, its wear resistance is equivalent to 266 times that of manganese steel and 171.5 times that of high chromium cast iron. According to our customer tracking survey for more than ten years, we can extend the service life of the equipment by at least ten times under the same working conditions.
It density is 3.5g / cm, only half of the steel, which can greatly reduce the equipment load.
Quality is our culture!
