Alumina Ceramic is a fine grain ceramic material that has excellent thermal and wear resistant properties. Our Alumina Ceramic is 99.7% pure, and has a high resistance to abrasion, high dielectric strength, and excellent resistance to acids. Alumina Ceramic is an ideal material for demanding functional concept testing. This material can replace traditional ceramic prototyping while drastically reducing lead time. See the data sheet here for more information. Also, please see our Ceramics Design Guide and FAQ page for more information on our engineered ceramics.
