Constellium produces armor for lab

RAVENSWOOD – Constellium Rolled Products in Ravenswood has made a massive armor plate for the U.S. Army Research Laboratory.

The project could lead to improve protection in ground vehicles, the Army said.

The 6-by-140-by-240 inch plate was shipped in May and was the largest armor plate ever produced with Alloy 7020, an alloy never before processed in the facility, using the world’s largest stretcher to meet the Army’s critical demand requirements, the company said.

Alloy 7020 can be used in armored vehicles and frames for motorcycles and bicycles.

Constellium cited its Armor Sales team and a strong partnership with the research laboratory in its selection to participate in the high-visibility military R&D project.

The project required an expedited production time to meet the Army’s schedule and multiple departments working together toward a common goal, the company said.

“First, I would like to express my gratitude for a job well done. To produce one of the largest aluminum plates in an alloy that has never been processed in Ravenswood on a timeline that was nothing short of ridiculous is an incredible achievement and a credit to Ravenswood and the whole Constellium team,” Bryan Cheeseman, team leader of Material Manufacturing and Technology Branch at the U.S. Army Research Laboratory, said. “If successful, the program has the potential to significantly increase the force protection of a ground combat vehicle.”

Constellium Rolled Products at Ravenswood employs more 900 employees and is the largest employer in Jackson County. The Ravenswood plant is among the world’s largest rolled products facilities with the most powerful plate stretcher in the world, the company said.

The plant produces aerospace plate, armor plate, general engineering plate, rail car sheet, tank trailer and truck body sheet and coil, truck and trailer roof coil, marine plate, sheet and coil, common alloy sheet and coil for aerospace, defense, transportation, marine and industrial applications.
