New aluminium alloys to support recycling by diecasters

Rio Tinto is introducing a new family of unique aluminium alloys designed to allow North American diecasters to increase their use of recycled content in the production of automotive parts, delivering improvements on both environmental footprint and production costs. The company’s new high-quality alloy series has been developed for high pressure vacuum diecasters to mix with their own scrap and recycled cleaned crushed wheels. As an alternative to buying lower grade secondary remelt ingots, the final blend will cost less, have lower carbon footprint and meet stringent industry standards. The company’s technical marketing experts will work with customers to tailor specific mixes of alloy and recycled content to meet their needs.

With expertise provided through its Avida research and development centre, Rio Tinto has the capacity to produce up to 100,000 metric tons of the new alloy series per year across its Canadian sites, which makes some of the world’s lowest carbon footprint primary aluminium.
