Abstract

PURPOSE: To obtain the flexible tube having excellent stress corrosion cracking resistance, etc., by cooling the tube material of copper base alloy after having been heated rapidly, by forming the wavelike shape so that the working degree of the valley part may become larger than that of the peak part and then by quenching after having been annealed by heating rapidly.
