Description
Alumina precision ceramics is a ceramic material based on aluminum oxide (AL) and is used in thick film integrated circuits.
Alumina precision ceramics have good conductivity, mechanical strength and high temperature resistance. It should be noted that ultrasonic cleaning is required.
Alumina ceramics have a variety of uses to meet daily and special performance needs.
95 aluminum oxide is mainly used as parts that are not prone to wear.
