Ford, Alcoa collaborate on more formable and design-friendly next-generation aluminum alloys

Ford Motor Company and Alcoa Inc. are collaborating to produce next-generation automotive aluminum alloys that are more formable and design-friendly.

Ford will use Alcoa’s Micromill® material in multiple components on the 2016 F-150 - becoming the first automaker to use the advanced automotive aluminum commercially. The companies entered into a joint development agreement to collaborate on next-generation aluminum alloys for automotive parts using Micromill™ technology.

‘‘Light-weighting enables us to design vehicles with great customer attributes – like the F-150, which can tow more, haul more, accelerate quicker and stop faster than the previous F-150, and is more fuel-efficient than ever,” said Raj Nair, Ford group vice president and chief technical officer, Global Product Development. “This collaboration supports our continued drive for innovation, as we research automotive applications for even greater light-weighting.”

Alcoa’s Micromill technology, announced in December 2014, produces an aluminum alloy that is 40 percent more formable than today’s automotive aluminum.

“Alcoa’s breakthrough Micromill technology offers highly differentiated automotive material with strength, weight, formability and surface quality combinations previously impossible,” said Klaus Kleinfeld, Alcoa chairman and chief executive officer. “This high-tech aluminum will give Ford a true material edge enabling greater design flexibility and better vehicle performance – making the concept cars of tomorrow a reality.”

The increased formability of Micromill aluminum makes it easier to shape into intricate forms, such as the inside panels of automobile doors and external fenders. The increased material strength allows for the use of thinner aluminum sheet without compromising dent resistance.

Micromill is the fastest, most productive aluminum casting and rolling system in the world combining multiple technologies into a streamlined production system. A traditional rolling mill takes around 20 days to turn molten metal into coil; Micromill does it in just 20 minutes.

Collaboration covers current and future Micromill alloys

Ford will begin using Micromill material in 2016 F-150 production in the fourth quarter of 2015, and plans to increase its use over the next several years on a range of vehicle components and future platforms. It is projected Ford’s use of Micromill material on its vehicles will more than double from 2016 to 2017.

Alcoa’s advanced alloys offer Ford the formability and strength required for greater flexibility in designing vehicles using complex parts. By using the highly formable material, parts constructed of multiple pieces can be manufactured as a single part – reducing complexity and assembly time. Target applications for the material include critical strength structural parts as well as exterior panels that must meet strict surface quality requirements. Aluminum alloy produced using the Micromill process has already been validated by Ford engineers.

The joint development agreement between Alcoa and Ford will further expand the existing suite of automotive alloys produced by Micromill technology for use on Ford vehicles.
