Alumina ceramic washer

1. Description

Alumina, or Aluminum Oxide, is a durable fine industrial ceramic that is commonly used in a variety of processing applications. Grind sintered alumina ceramics only using a diamond tool. Alumina ceramic exhibits exceptional hardness and wear resistance, as well as low corrosion, excellent electrical insulation and bio-inertness. Alumina (Al2O3) is a very heat-stable ceramic material of excellent temperature stability. Al2O3 ceramics with a purity of 95% to 99% are the most commonly used kind of technical ceramics. UNIPRETEC offers a variety of alumina ceramic shaping methods, including molded injection, die pressing, slip casting, extrusion, and cold isostatistically pressing.

Alumina is used in a wide spectrum of purity concentrations, ranging from ultrapure to added-substance grades. Although the purity of Al2O3 in finished products usually ranges between 90 and 99.8%, UNIPRETEC tends to work with materials with a purity of 95 to 99 percent.
