Abstract
The wear resistant aluminum alloy elongate body contains 7-13 mass % of Si, 0.001-0.3 mass % of iron, 2.0-5.0 mass % of Cu, 0.3-1.0 mass % of Mg, 0.001-0.3 mass % of Mn, 0.001-0.3 mass % of Cr, 0.003-0.03 mass % of Sr, 0.005-0.05 mass % of Ti, and the remaining part of Al and unavoidable impurity. The size of Si grains existing in the elongate body is, by the average value, at most 10 μm and by the maximum value, at most 30 μm, and the size of the Si grains in the range of down to 1.5 mm deep from the surface is, by the maximum value, at most 6 μm. Further, crystal texture of Al alloy is one selected from the group consisting of hot rolled texture, re-crystallized texture and mixed texture of hot rolled texture and re-crystallized texture.
