Ford, Alcoa announce next generation of aluminum lightweighting for F-150

Ford likes what it has seen with the use of aluminum in its world-beating F-150 pickup trucks. Now, the Blue Oval is working with Alcoa to use that company's Micromill material to increase the amount of aluminum in Ford vehicles. In fact, Ford will start using Micromill on 2016 model-year F-150s later this year, and will double the material's use in 2017.

The purpose, as you might suspect, is light weighting, which allows Ford to boost towing capacity while adding as little weight as possible. Ford will be the first automaker to use Micromill, and will use it in both structural components and exterior panels. Micromill's rolling-mill system cuts the time it takes to turn molten metal into coil to 20 minutes from about 20 days.

Already, Ford has had positive results by using aluminum on its leading pickup truck model. In April, it was announced that the 2015 Ford F-150 achieved a five-star Overall Vehicle Score in the National Highway Traffic Safety Administration's testing. Safety features like inflatable seat belts, adaptive steering columns and a forward collision warning system helped matters.

General Motors may have taken note of those results, even after running an ad campaign touting its continued use of steel over aluminum. Last month, GM said it would sink $877 million into its Flint, MI, truck factory. Reuters said much of the expense was to convert many of the bodies for models like the Chevrolet Silverado and GMC Sierra pickups into aluminum. You can take a look at Ford's press release below. Show full PR text 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 to ensure it meets the stringent requirements for producing high-quality parts, especially the kinds of complex structures that make up F-150.

"The door inner is one of the most difficult parts in automotive stamping," said Peter Friedman, Ford global manager of structures and stamping, Research & Advanced Engineering. "The ability to produce an alloy using Alcoa's Micromill technology to make that part is a real statement for how this process can benefit the automotive industry and Ford in particular.

"This technology will help Ford to produce the type of vehicles our customers want," added Friedman. "We believe the technology can be used to develop new alloys that will improve our ability to form complex parts, which will help in both design and efficiency."

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. New alloys will improve design flexibility on lightweight parts and provide better vehicle performance – helping Ford produce the types of quality, lightweight vehicles customers want. Source

    Why Ford decided to create a 'Smart Mobility' subsidiary

    For more than 100 years, Ford has built cars for the masses. On Friday, the company took its most concrete steps to date to splinter that business model among emerging alternatives to traditional car ownership. Ford announced it has created a new subsidiary, Ford Smart Mobility, that will serve as an incubator for potential opportunities that range from ride sharing to fractional car

    Ford recalls over 8,500 vehicles in three campaigns

    Ford issued three separate recalls Wednesday affecting over 8,500 vehicles, including 7,000 of its most important models. The 2015 and 2016 Explorer and F-150 represent the bulk of the recalled vehicles. In an unusual instance, the affected models come from two different facilities and ride on two different platforms but suffer from the same issue – a bad weld on the driver's rear seatback.
