Wear resistant alumina ceramic rod

Wear resistant alumina ceramic rod is a high-performance ceramic material mainly composed of alumina (Al ₂ O ∝). The alumina content is usually above 95%, and some high-end products can reach over 99%.
High hardness: The Mohs hardness can reach level 9, second only to diamond and cubic boron nitride, which can effectively resist wear and scratches.
High wear resistance: It exhibits excellent wear resistance under heavy loads and high friction environments, significantly extending the service life of equipment.
Corrosion resistance: It has excellent corrosion resistance to acids, alkalis, and various chemical media, and is suitable for harsh chemical environments.
High temperature resistance: It can be used for a long time in high temperature environments up to 1600 ° C or above, and some special products can even withstand temperatures above 1700 ° C.
Low thermal expansion coefficient: Excellent dimensional stability at high temperatures, avoiding deformation or cracking caused by thermal expansion and contraction.
Electrical insulation: It exhibits excellent electrical insulation performance at both high and room temperatures, suitable for the electronics and electrical industries.
