Abstract
A method for manufacturing a clad material (110, 410) includes performing a Ni plating treatment on a Cu material (104, 404) made of Cu or a Cu-based alloy to make a Ni-plated Cu material in which the Cu material is covered with a Ni plating layer, performing a heat treatment on the Ni-plated Cu material at a holding temperature of 650° C. or higher and 850° C. or lower, and bonding an Al material (102, 402) made of Al or an Al-based alloy and the Ni-plated Cu material on which the heat treatment has been performed to each other by rolling to make the clad material.
Claims9
A method for manufacturing a clad material, comprising:
- performing a Ni plating treatment on a Cu material made of Cu or a Cu-based alloy to make a Ni-plated Cu material in which the entire surface of the Cu material is covered with a Ni plating layer;
- softening the Ni-plated Cu material by performing a softening heat treatment as a first heat treatment on the Ni-plated Cu material at a holding temperature of 650° C. or higher and 850° C. or lower before rolling;
- bonding an Al material made of Al or an Al-based alloy and the softened Ni-plated Cu material on which the softening heat treatment has been performed to each other by rolling to make the clad material after performing the softening heat treatment;
- and
- performing diffusion annealing as a secondary heat treatment on the clad material at an annealing holding temperature of 500° C. or higher and 600° C. or lower which is lower than the holding temperature after rolling.
