Alumina Ceramic Ring Industrial Mechanical Alumina Ring Wear Resistant
Alumina, or Aluminum Oxide, is a popular ceramic material in technical manufacturing, with many exceptional properties ranging from corrosion resistance and dielectric strength, to hardness and mechanical properties, to thermal and electrical insulation. It comes in a number of purities and is available in many forms, making it a frequent choice across many different industries.
Low-toleranced components can be pressed prior to firing, machining alumina after firing requires specific machining techniques, tooling, and strategies.
We have made components and assemblies for a massive number of programs, including aerospace, solar system, as well as for medical, semiconductor, and research applications.
