New development: corrosion resistance of ultra high-strength

7xxx-series alloys• A concern with 7xxx structural alloys is catastrophic failure in service due to stress corrosion cracking.

• We test materials under multiple stress loading modes beyond plastic yield and in different corrosive

environments to ensure immunity to SCC in service.

• Overaged copper containing 7xxx-series alloys provide robust resistance in these tests.

• Ultra v1 has successfully passed all these tests.

1Deep industrial legacy

We are an established aluminum industry player with roots in some of the oldest

aluminum companies in the world, including Pechiney, Alusuisse, Alcan (now

Constellium), Sumitomo Light Metals, and Furukawa-Sky (now UACJ).

2Automotive experience

Both companies have very broad experience in supplying aluminum to the automotive

industry.

As established players in Europe and Japan, the parent companies supply aluminum

Automotive Body Sheet to premium OEMs like Daimler, BMW, Audi and Lexus.

3Best-in-class assets

We are running a brand new state-of-the-art finishing line with cold coils supplied from

some of the world’s foremost rolling mills (Logan, Muscle Shoals).

4Innovation

Both Constellium and UACJ have world-class R&T centers and are leveraging this to

provide our customers with innovative products which meet both performance and light-

weighting needs
