Copper and Tin-Plated Aluminum Conductor U.S. Patent 5,665,219. Sept 9, 1997 N. Yu, assignor to AxonCable SA, Eylonfmirai, France

A process for continuous manufacture of

an electrical conductor. the conductor hav- ing an at least partially aluminum-based central core coated hy continuous elec-

trodeposition with at least one metal layer,

the process including successively with in- termediate rinsings the degreasing of the core, its pickling, and the treatment of its

surface to create thereon bonding points in the form of microscopic metal seeds, the

process further comprising electrochemi- tally depositing copper in a first aqueous bath maintained at a temperature between

20 and 60°C. containing KCN. CuCN, KZCB3, and KNaC,H,O,, with a current intensity of between 1 and IO Aldm’, rins-

ing the conductor at ambient temperature; electrochemically depositing tin on the

conductor in a second aqueous bath main- tained at a temperature of between 20 and 60°C containing essentially tin and meth- anesulfonic acid and. optionally, additives,

with a current intensity ot between I and IO0 A/dm’, and rinsing with water at 60°C.

the conductor having a coating, which pro- vides a wetting angle between IO and 60’.
