Metals Knowledge: Recycling Aluminum Alloys

Posted by tjdetai on August 10th, 2015

The growth in aluminum usage in transportation applications, relative decline in aluminum beverage can recycling, and increasing reliance of the fabrication industry on secondary aluminum have combined to create new needs in both the materials design and processing space. To most economically utilize these scrap streams, new approaches to developing acceptable materials processed to control properties suitable for an expanded range of applications are needed.

Recycling aluminum alloys has been shown to provide major economic benefits. As a result, it is appropriate for the aluminum industry to identify, develop, and implement all technologies that will optimize the benefits of recycling.Aluminum recycling in North America and Europe is a mature, well-developed economy. It gained momentum after World War II following rapid economic and industrial growth, and especially after the introduction of the aluminum beverage can with its easy-open end. While today’s recycling metals markets also include ferrous metals like iron and steel, and nonferrous metals like copper and brass, aluminum recycling is the engine of recycling economics.
