• Ultra ONE™ Wheel is 47 Percent Lighter than Steel Wheel of Same Size
• Can Help Save Up To 1,400 Pounds Per Rig
• Alcoa’s New MagnaForce™ Alloy Behind the Breakthrough Innovation
• One of Largest US Flatbed Carriers, TMC Transportation, Converting to New Wheel

Alcoa (NYSE: AA) has rolled out the world’s lightest heavy-duty truck
wheel. This latest Alcoa innovation, the Ultra ONE™, will help trucks
shed pounds for increased payload and fuel efficiency.

Unveiled at the Mid-America Trucking show in Louisville, Kentucky,
Alcoa’s new 40-pound wheel is 47 percent lighter than steel wheels of
the same size. The Ultra ONE can help save up to 1,400 pounds per rig,
enabling fleets to carry more goods while meeting stringent federal
emissions regulations. Underscoring the importance of lightweighting to
the industry, one of America’s largest flatbed carriers, TMC
Transportation, is converting its fleet to the Ultra ONE starting in
2014.

“Alcoa continues to reinvent the wheel. Our new innovation is heavy-duty
without the ‘heavy,’ and it looks great, too,” said Tim Myers,
President, Alcoa Wheel and Transportation Products. “Alcoa’s unique mix
of manufacturing, technology and lightweight metals expertise enabled
this breakthrough. Major fleets, such as TMC Transportation, are already
lining up to take advantage of it.”

Fleets have increasingly converted to aluminum wheels that offset the
weight of necessary pollution-control equipment used to meet federal
emissions regulations. Lighter wheels also improve fuel economy, making
up for rising fuel prices and helping move goods in a cleaner way. And
if trucks burn less fuel, they emit fewer greenhouse gases. Replacing
steel wheels with aluminum wheels on an 18-wheeler offsets the annual
carbon footprint of an average family of four in America. In addition,
Alcoa’s aluminum wheels are six times brighter than competitors’ wheels,
giving them strong aesthetic appeal, and because they are corrosion
resistant and do not require stripping and repainting, lower operators’
maintenance and operating costs.

“As the largest privately owned flatbed trucking company in the United
States, TMC Transportation trucks haul heavy loads across America every
day, and each pound we can reduce helps us lower costs and move more
goods,” said Harrold W. Annett, Chairman and Chief Executive Officer of
TMC transportation. “The Ultra ONE wheel is part of our total commitment
to quality, through which we reduce waste and ensure customer
satisfaction.”

To take out five pounds out of its lightest heavy-duty truck wheel,
Alcoa’s experts at the Alcoa Technical Center—the world’s largest light
metals research center—invented a new alloy, the patent-pending MagnaForce™
alloy. It is on average 17 percent stronger than the industry standard,
Alcoa’s 6061 alloy, in similar applications.

Alcoa’s wheels business has been launching a progression of innovations
since inventing the forged aluminum wheel in 1948, widening the
Company’s lead over competitors. Alcoa’s wheels business has grown at a
22 percent compounded annual growth rate from 2009 to 2013—with 67
percent of sales driven by proprietary technologies—making it one of
Alcoa’s fastest growing businesses. The company is expanding its wheels
presence in Europe and into China and Brazil to capture growing global
demand for its wheels.
