Alumina (Al2O3) ceramic has a high melting point, high hardness, and good chemical stability. It is a good material for high temperature and chemical corrosion resistance. Alumina plates are available in different sizes and thicknesses. Custom shapes and sizes are available.

High-purity alumina products can withstand extremely high temperatures under reducing, inert, or high vacuum conditions. They maintain good chemical resistance at high temperatures and have excellent wear and abrasion resistance.
