Apple has played a crucial role in an international joint venture that could forever change global manufacturing of aluminum. A key component used in the production of Macs, iPads, iPhones and Apple Watch products, many technology companies like Apple prefer aluminum because of its strength and lightness as well as the various ways it can be treated.

By using aluminum in its products at scale, Apple has been able to find ways to make production more effecient and less wasteful as well as develop new processes.

Leading aluminum manufacturing companies Alcoa and Rio Tinto have developed, "a revolutionary process to make aluminum that produces oxygen and replaces all greenhouse gas emissions from the traditional aluminum smelting process. The technology represents the culmination of decades’ worth of research and development," Apple's statement said. 

According to the news. Alcoa, Rio Tinto, the Government of Canada, the Government of Quebec and Apple agree to provide a combined investment of CAD $188 million, which is a large investment in Canada, where the smelting will take place.

Today’s announcement in Saguenay, Quebec, which was attended by Canadian Prime Minister Justin Trudeau, Quebec Premier Philippe Couillard and Apple Senior Director Sarah Chandler, involved research and development that has spanned decades. Apple’s involvement started in 2015, when three of its engineers went in search of a cleaner, better way of mass producing aluminum

Fun fact about aluminum, while it is used today in everything from aircraft parts to computer bodies, it was once the rarest and most expensive element in the world and was valued more than gold. The cap of the Washington Monument is made from aluminum. althought at that time it was worth $1 per ounce.
