Abstract
In the manufacture of a bearing material containing an aluminum base alloy, one surface of a steel strip is washed and roughened; the aluminum base alloy is spread on the surface of the steel strip; and the aluminum base alloy and the steel strip are hot-rolled in the air to pressure-bond the former to the latter into a unitary structure. Prior to spreading the aluminum base alloy, an aluminum powder which well adheres to the steel strip may also be spread on the surface of the steel strip.
