Latest Alcoa Armor Now Specified by U.S. Army Research Lab For Highest Strength, Troop Protection in Military Vehicles

October 10, 2013

Alcoa (NYSE: AA) today announced its latest armor product is now
specified for use by the U.S. Army Research Lab (ARL) for use in U.S.
military vehicles. Alcoa’s ArmX® 5456-H151 armor plate meets
the U.S. military’s highest performance standards for strength, blast
absorption, and ballistics resistance for armored combat vehicles where
weldability is a material requirement. Alcoa aluminum and armor have
been used by the military for decades in vehicles ranging from the
Bradley Fighting Vehicle to the Humvee.

“Alcoa’s military-grade aluminum alloys and products have helped the
U.S. military protect troops for generations,” said Mark Vrablec,
President of Global Aerospace, Transportation and Industrial Rolled
Products at Alcoa. “Alcoa’s latest innovation allows military vehicle
manufacturers to continue building with the highest level of durability
and troop protection through welding processes when assembling the
vehicle, or performing repairs in the field.

“This new product offers more than 20 percent improvement in strength
compared with the baseline 5083-H131 weldable armor plate, as well as
improved ballistic and blast performance,” added Vrablec.

Alcoa’s 5456-H151 armor plate, formerly referred to as CR56, joins the
family of Alcoa next-generation ArmX® brand armor solutions (click

developed by scientists at the Alcoa Technical Center, the world’s
largest light metals innovation and R&D center located outside
Pittsburgh, Pa., in collaboration with metallurgists and production
engineers at Alcoa Davenport Works, the world’s premier aerospace,
defense, and automotive rolling mill. ArmX® 5456-H151 armor
plate will be produced at Alcoa Davenport Works, where manufacturing and
quality control testing is conducted to ensure the military’s highest
specifications for weldable aluminum armor plate are met.

Alcoa’s ArmX® 5456-H151 armor was tested and has been
successfully demonstrated on the U.S. Army’s Fuel Efficient Ground
Vehicle Demonstrator vehicle, known as FED ALPHA, a prototype vehicle
that Alcoa helped develop to demonstrate lightweight, fuel-efficient
technologies while maintaining vehicle durability and troop safety (click
for more information on the FED vehicle
). FED ALPHA’s lightweight
aluminum structure makes the vehicle up to 10 percent lighter than a
comparably sized steel vehicle and reduces fuel consumption by 6-7
