Abstract

See full text

The present invention relates to techniques for producing 2024 and 7075 aluminum alloys by recycling waste aircraft aluminum alloys, which belong to technical fields for circular economy. The present invention develops techniques for obtaining the 2024 and 7075 aluminum alloys by subjecting waste aircraft aluminum alloys as raw materials to pretreatment, smelting, impurity removal, melt ingredient assay, ingredient adjustment, refining, and casting. Through utilizing the waste package aluminum alloys and the waste aluminum pop-top cans to adjust the ingredients, the waste aircraft aluminum alloys would be recycled at a lower cost without downgrading. The present invention has some advantages, such as low cost, and applicability for industrial production, as well as prominent economic benefit.
