Founction of Ceramic Eyelets
Ceramic eyelets are made by different kind of materials, but all of them with same founction that are typically mounted in a machine to provide a smooth exterior surface for a wire or yarn to run over. Main ceramic eyelets are made by follow material:
- Aluminum Oxide (Al2O3)
- Titanium Oxide ceramic eyelets
- Zirconia ceramic eye Ceramic eyelets
Main Material of Ceramic Eyelets
Alumina or aluminum oxide (Al2O3) in its various levels of purity is used more often than any other advanced ceramic material. So most of ceramic eylets is made by Aluminum oxide. Here belows you can check the technic parameter of Aluminum oixde ceramic eyelets and guide.
