PROBLEM TO BE SOLVED: To provide a wear resistant aluminum alloy long-length body excellent in mechanical properties and cold workability and to provide a method for producing the same. SOLUTION: An aluminum alloy containing, by weight, 7 to 13% Si, 0.001 to 0.2% Fe, at least one of Mn and Cr by 0.001 to 0.25%, 0.003 to 0.03% Sr, 0.005 to 0.03% Ti, and the balance Al with inevitable impurities is melted and is subjected to continuous casting to make an ingot, and this ingot is subjected to hot rolling in the temperature range of 350 to 520 deg.C at a working degree of 40% or more and is subjected to heat treatment to produce the wear resistant aluminum alloy long-length body having a hot rolled structure and a recrystallized structure.
