LONGSUN contact materials with graphite fibers embedded into the Ag matrix are improved both regarding to the over temperature properties and to the switching life time, comparing to conventional silver/graphite can be exploited. As the graphite content increase ductility dramatically decreases. Improvements of graphite can be exploited. As the material are popular in sliding contact applications where the lubricating properties of graphite can be exploited. As the graphite content increase the ductility dramatically decrease. Improvements in production
