(Alumina Ceramic Rod)

Brand Name Origin: Creating Toughness from Dirt

Our journey began in a moderate lab, far gotten rid of from the gleaming high-rises of corporate headquarters. It began with a stack of white powder– alumina– and a persistent refusal to approve the limitations of steel. The founders, a team of ceramic engineers and thermodynamicists, were obsessed with a single inquiry: Just how can we create a material that is as hard as diamond yet as functional as plastic? They recognized that light weight aluminum oxide, the third most bountiful mineral in the earth’s crust, held the key to a brand-new commercial revolution. However, the change from raw bauxite to a high-performance ceramic rod is a path stuffed with clinical challenges. In the very early days, the industry depended on heavy, weak ceramics that were challenging to device and vulnerable to tragic failing. We sought to alter this standard.
