7. 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.

Corrosion test method (4 weeks)
ASTM G44
(alt. Immersion, 27°C)
ASTM G85-A2
(Cyclic, 50°C)
WVSA
(Constant humidity
100%, 50°C)
Stressstate
75% YS
uniaxial stress
U-bend

8. New development: hot forming for Ultra
B-pillar trials at C-TEC:
• Blank heating during few minutes at SHT temperature
• Transfer
• Stamping in cold dies
• Press quenching (die closing maintained)
• Total forming cycle time ~20 seconds
• Heat-up time: 8 minutes

1
Deep 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).
2
Automotive 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.
3
Best-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).
