Low-friction boride alloy

A cutting tool made of an aluminum-magnesium-boron alloy, nicknamed BAM, takes a heavy cut in a hardened stainless steel turning. The alloy, developed by Ames Laboratory metallurgists Bruce Cook and Alan Russell is extremely hard but also has a coefficient of friction that is lower than Teflon. The material is being studied as a nanoscale coating for pump components and industrial cutting tools to reduce friction and thereby boost equipment energy efficiency.
