Aluminum composite material and method of producing the same
An aluminum composite material has a surface structure in which a part of lubricative granules projects by 2 μm to 25 μm from the surface of the aluminum alloy base material. The lubricative property of the lubricative granules is utilized sufficiently, and the abrasion of the aluminum alloy base material can be prevented. Further, according to a manufacturing method of the aluminum composite material where the surface of the aluminum alloy base material is eroded with a etching solution, a level of erosion of the aluminum alloy base material can be easily adjusted and a surface structure from which the lubricative granules project can be formed sufficiently.
