One of the main problems in aluminum recycling is the removal of impurities unavoidably mixed from recycled materials. If harmfulness of impurities can be made harmless, an alloy with impurities could be used in the same manner as a high purity alloy. In this work, the recovery of strength of 7050 aluminum alloy with impurities by the RRA treatment was examined. When the solution heat treatment at a slightly higher temperature (500°C) than that of commercial condition is made and then the RRA treatment is applied, the alloy containing less than about 1% of impurities (Fe+Si) reveals the strength comparable to that of commercial purity alloy. The RRA treatment is useful for compensation of strength decreased with impurities.
