Abstract

The invention discloses a regenerated wrought aluminum alloy melt. The regenerated wrought aluminum alloy melt comprises the following components: 95%-98% of 6xxx series waste aluminum, 0.8%-1.4% of metal Mg, 0.6%-1.2% of metal Cu, 0.1%-0.25% of metal Mn, 0.2%-0.7% of metal Cr, 0.3%-0.7% of an Al-Ti series refiner, 0.2%-0.6% of an Al-10Sr alterant and 0.1%-0.4% of a stabilizer. According to the regenerated wrought aluminum alloy melt, metal aluminum liquid is subjected to residue filtering treatment, and meanwhile, added metal is subjected to refining purification treatment, the purity of the mixed solution is guaranteed, and in addition, the stabilizer is added into the mixed solution, fusion stability between the solutions is guaranteed, and the quality and comprehensive performance of the prepared aluminum alloy are effectively guaranteed.

Description

technical field [0001] The invention relates to an aluminum alloy melt, in particular to a recycled deformed aluminum alloy melt, which belongs to the technical field of aluminum alloys. Background technique [0002] Aluminum alloy is an alloy based on aluminum with a certain amount of other alloying elements added, and is one of the light metal materials.
