FIELD: manufacture of jewelry articles, possibly in jewelry industry at making small springs of rod type locks of gold alloys.
SUBSTANCE: method comprises steps of forming wire of gold alloy by deforming during several stages at intermediate annealing procedures between said stages; at last stage of wire forming deforming alloy by drawing it at total reduction degree 65 - 85%; then winding spring of formed wire. In preferable variant of invention last stage of drawing is realized during eight passes at total reduction degree 77.8%. The most effective method of forming springs is realized at using gold of purity degree 585.
EFFECT: enhanced manufacturing effectiveness, improved quality of articles due to their enhanced elastic properties.
