A composite coating for electrical connectors is provided. The coating contains a ductile metal matrix and an uniformly dispersed polymer component. The polymer component is present in a concentration effective to reduce frictional forces generated when inserting an insertion component into a socket. The composite coating has lower friction and improved fretting corrosion resistance as compared to an electrodeposited tin coating. One preferred coating contains 0.5 weight percent polytetrafluoroethylene in a tin matrix.
