METHOD FOR MAKING RECTANGULAR CROSS-SECTION STRIP OF COPPER-SILVER ALLOY Russian patent published in 2008 - IPC B21C1/00 

Abstract RU 2317867 C1

FIELD: improved commercial properties of strips of copper-silver alloy containing silver and designed for producing windings of rotors of turbine generators.

SUBSTANCE: known method for producing strip of copper-silver alloy comprising steps of using as base of alloy cathode copper; producing ingot by semi-continuous casting; making blank by means of hot deformation, for example by pressing; drawing hot deformed blank to intermediate blank; full recrystallization annealing of intermediate blank and finish drawing of it to ready strip is realized at using cathode copper of MOOc kind and performing finish drawing at percentage reduction ε = [(Fo - F1)/Fo] x 100% = 6 - 13 % where Fo - cross section area of intermediate blank after full recrystallization annealing, F1 - cross section area of ready strip.

EFFECT: lowered specific electric resistance of material, improved stability of mechanical properties of articles.
