METHOD FOR PRODUCING CLAD MATERIAL FOR ALUMINUM BEARING

PROBLEM TO BE SOLVED: To improve the shape precision of a clad material in a thickness direction or width direction in a method for producing the clad plate to be used for the material for forming an aluminum bearing by joining an aluminum material and a steel material. SOLUTION: The aluminum material and the steel material are rolled and pressure-welded, secondary rolling for increasing the shape precision in the thickness direction of the clad material between the aluminum material and the steel material is performed, and thereafter, heat treatment is performed. Alternatively, the clad material is divided into a plurality of parts in a width direction, and thereafter, heat treatment is performed. Alternatively, the clad material is divided into a plurality of parts in a width direction, then, secondary rolling and drawing are performed, and, finally, heat treatment is performed.
