Bearing material including aluminum as its main ingredient and at least one lubricant additive, produced by compacting a powder material including aluminum as its main ingredient and at least one lubricant additive into a desired shape, subjecting the compacted and shaped powder material to heat treatment, extruding the heat-treated material and then subjecting the extruded material to heat treatment. The bearing material thus formed has a structure in which the lubricant additives are uniformly distributed as fine particles of small size, and also has a high percentage of elongation. |
