COLD-ROLLED PROFILE FOR COLLECTORS OF ELECTRIC MACHINES Russian patent published in 2016 - IPC C22C9/02 

FIELD: metallurgy.

SUBSTANCE: invention relates to semi-products electrical purposes, conforming of copper and copper alloys, particularly to profiles for fabrication of collectors of electric machines. Cold-rolled profile from copper-based alloy for collectors of electric machines in cross-section features shape of isosceles trapezium with angle between lateral sides of trapezium, not exceeding 6°, and alloy, from which it is made, containing following components ratio, wt%: tin 0.1-1.3, silver 0.01-0.1, phosphorus of not more than 0.03, admixtures to 0.2, copper is rest.

EFFECT: improved processability profile due to increased wear resistance, relative elongation, ultimate strength, as well as electric conductivity, weldability and soldering.
