Abstract

PURPOSE:To manufacture a Cu clad Al tube excellent in adhesive strength of coated material and having a mirror surface by ironing an Al blank tube and a Cu blank tube in a state where they are combined with each other and integrating both in one body. CONSTITUTION:An Al blank tube 1 and a Cu blank tube 2 which each have a prescribed length are fitted in each other. Curled parts 1a, 2a are formed at one end of this fitted and double tube 3. Then a punch 4 is inserted into the Al blank tube 1 as an internal tube for ironing operation. In both blank tubes 1, 2 thicknesses are reduced by ironing operation, the Cu clad layer 21 is stuck firmly on the Al blank tube 11 and the surface of the Cu clad layer 21 is finished for a flat mirror surface having a roughness, Rmax <=1.0mum. Curled parts 1a, 2a are cut off and used as a straight tube material having a prescribed length.
