FIELD: metallurgy.
SUBSTANCE: invention refers to procedure of preparation of long-length items of small section of complex shape of wire type made of aluminium and its alloys and used in production of light and particularly light wires and cables before application of silver. The procedure consists in operations of wire de-fatting, washing and pickling in solution containing 8-100 g/l of potassium cyanide at temperature 18-25°C without current imposing with successive washing.
EFFECT: increased strength of adhesion of electro-deposit with base.
