Constellium’s W51 T6 proprietary alloy is a unique armored alloy certified by Nexter Systems for structural cast applications. It has already been used on Nexter’s vehicles for ram air exhaust door or firing sight shroud, and it is also undergoing CMI Defence ballistic testing.

Our A357 alloy, meanwhile, is being used for MBDA’s cruise missile body, and Renault Trucks Defense is using our A204 alloy for its VAB suspension box.
