Alcoa Introduces New Lighter, Stronger High-Load Aluminum Wheels Unavailable in Steel

Alcoa Wheel and Transportation Products (AWTP), an Alcoa (NYSE:AA)
business unit, introduced four new forged aluminum wheels, two of which
offer maximum loads per wheel currently unavailable in steel. The Alcoa
wheels are up to 44% lighter than steel equivalents and support the move
to higher-load-capacity tires. Alcoa introduced the new wheels at the 64^th
International Motor Show (IAA) Commercial Vehicles conference in
Hannover, Germany.

'We are constantly driving ourselves to design aluminum wheels that
offer our customers stronger and lighter options to steel that also
increase cargo capacity, fuel economy and reduce carbon emissions,? said
Alcoa Wheel and Transportation Products President, Tim Myers. 'There is
a definite trend within the commercial vehicle industry to move to
higher-load-capacity tires, and these new wheels address those needs.?

The two new aluminum wheels available at high-load capacities not found
in steel include an improved Alcoa global trailer wheel, and the first
aluminum 45mm offset trailer wheel for inloaders, trailers designed to
transport architectural glass plates and concrete parts. Both wheels
support the move to higher-load-capacity tires.

The improved trailer wheel has a maximum load of 5,500kg per wheel, a
near 6% increase to the previous Alcoa model, yet is 2.1kg lighter. It
is 22.8kg lighter than a comparable steel wheel.

The aluminum 45mm offset trailer wheel is 37% lighter than the steel
equivalent with a maximum load per wheel of 5,000kg.

New Alcoa forged aluminum wheels being introduced also include the:

• 
  135 FrontRunner, a 135mm offset truck wheel with maximum load per
  wheel of 5,000kg suitable for use on the front axles of Scania, DAF
  and Inveco trucks; the Alcoa wheel is 44% lighter than the steel
  equivalent and supports the move to higher-load-capacity tires;
  
• 
  80mm offset trailer wheel with a maximum load per wheel of 4,500kg for
  use with the new lightweight SAF 80 One axle by SAF Holland, a leading
  manufacturer and supplier of product systems and components primarily
  for trailers as well as trucks, buses and recreational vehicles.
  

The wheels are produced at the Alcoa Wheels plant in Hungary and are
available in a number of finishes including Brushed, Mirror Polished and
Dura-Bright ?.

The lighter, yet stronger, aluminum wheels for weight and fuel savings
and reduced carbon emissions exemplify Alcoa′s dedication to greener
transportation. Alcoa Wheel and Transportation Products affirmed its
dedication to environmentally friendly transportation at the IAA
conference by joining the Sustainable Development Charter of the
International Association of Public Transport (UITP). The Charter is
specifically dedicated to increasing awareness on the importance of
sustainability within the transportation sector. The Charter′s more than
150 global members commit to monitor, measure and to report on their own
sustainability performance, while sharing best practices with fellow
members.
