CoB3W3
metal· JVASP-24610· CoB3W3
CoB3W3 is a cobalt-tungsten boride compound, part of the refractory metal boride family known for extremely high hardness and thermal stability. This material is primarily of research and specialized industrial interest, valued in applications requiring exceptional wear resistance and thermal shock tolerance where conventional cemented carbides or ceramics fall short. Its high density and hardness characteristics make it relevant for cutting tools, abrasive applications, and high-temperature structural components, though limited commercial availability and processing complexity mean adoption remains restricted to demanding niche applications rather than mainstream use.
