High hardness and capacity for close dimensional tolerances make Ceramic Rods and Plates suitable for forming abrasion resistant components that stands up to corrosion and thermal extremes. Widely used as electrical insulators, and in chemical and aerospace applications, parts made of Bisque Alumina Ceramics are readily fabricated using conventional cutting tools; however carbide tools last longer. Parts can be easily prototyped or mass produced and after machining, further fired to achieve ultimate properties if required.Bisque Alumina is an Aluminum Oxide fired to approximately 2475F (1357C). It can be used in its bisque form or in a fully fired state. When fully fired to approximately 3100F (1704C) it becomes a dense, hard material and both electrical and mechanical properties increase. When fully fired, Bisque Alumina shrinks between 15 percent and 18 percent. Dimensions are nominal due to moisture content.
