<p>A wear-resistant aluminum alloy excellent in staking property, characterized in that it has a chemical composition: Mg: 0.1 to 0.45 wt %, Si: 3.0 to 6.0 wt %, Cu: 0.01 to 0.5 wt %, Fe: 0.01 to 0.5 wt %, Mn: 0.01 to 0.5 wt %, Cr: 0.01 to 0.5 wt % and balance: Al and inevitable impurities; and an extruded product made of the aluminum alloy. The aluminum alloy and the extruded product has good wear resistance, high strength and high hardness, and also exhibits good staking (sticking) property, which has been conventionally considered to conflict with good values in the above-mentioned characteristics.</p> |
