Alumina Ceramic Connectors , Ceramic Connectors , Al2O3
Ceramic connectors are usually designed as block structures with specific geometric shapes, with precise holes and grooves that can be precisely combined with other devices.
Alumina is a very hard ceramic material that is resistant to high temperature and corrosion while also having very superior mechanical strength. The compressive strength exceeds 2000MPa and can work stably in some harsh high-pressure environments!
We provide you with customized ceramic connectors with 85-99.9% purity. In addition to alumina, there are many other materials for you to choose from!
