Abstract
A low friction, low contact resistance coating for electrical terminal members, especially members made of copper base alloys and low carbon steel alloys and plastics, is formed of a coarse electroplate of tin or silver characterized by grains having an average dimension in the range of about 0.5 to 10 micrometers where such grains carry very small particles of polytetrafluoroethylene or the like having average diameters in the range up to about 0.30 micrometers.
