  • Method for manufacturing aluminum or aluminum alloy clad steel sheet or strip
    Patent number: 4202709
    Abstract: A method for manufacturing an aluminum or aluminum alloy clad steel sheet in an easy, economical manner. An aluminized steel sheet obtained by applying aluminum or an aluminum alloy to a steel sheet by hot dipping is heated to a temperature between 100.degree. and 550.degree. C. Then, an aluminum or aluminum alloy sheet having its bonding face cleaned and having room temperature is superposed on one side or each of two sides of the aluminized steel sheet. The superposed sheets are rolled together to a draft reduction percentage of 10 to 40% to roll bond the aluminum or aluminum alloy sheet or sheets with the aluminized steel sheet. Then, if desired, the roll bonded sheets are further subjected to either one or both of finish rolling and/or a softening treatment. An aluminum or aluminum alloy clad steel sheet thus obtained has excellent strength, corrosion resistance and bending formability.
