FIELD: process engineering.
SUBSTANCE: invention relates to powder metallurgy, particularly, to making of semi-finished part for electric terminals in the form of a strip. Unit is made from silver-based composite including one or more metal oxides or carbon. Coating of basic metal powder is applied on said composite unit. Coated unit is compacted and annealed in reducing or inert atmosphere or in vacuum. This prevents formation of eutectic melt of composite silver and basic metal that coat the composite silver-based unit. Annealed unit is subjected to extrusion to obtain strip with top side of composite and bottom side of silver or silver-based alloy.
EFFECT: simplified production of electric strip-type terminals.
