Osmium Powder
Osmium powder is a highly dense, ductile metal powder. Available in 6 variations, it can be customized to meet the needs of many applications. The hardness and wear resistance of Osmium Powder means it is commonly used for electrical contacts and instrument pivot bearings. Its high density also allows it to be used as ballast for aircraft control and instrument gyroscopes. Osmium Powder’s properties make it ideal for the precision engineering of small components where high density is required.
