ALmitas+ U-ALight 6 Series (6000 Series Alloys)
Share6000 series alloy sheets for body panels that excel in formability and display high strength after coat-baking
U-ALight is a new aluminum product series based on our conventional automotive products with the added benefit of lower environmental impact.
Features
- UACJ offers a wide selection of 6000 series alloys that combine strength, formability, weldability, corrosion resistance, and high surface quality required of automotive panel materials.
- Highly bake-hardenable U-ALight 6S is recommended for parts where dent resistance is critical.
- U-ALight 6HF exhibits high ductility (elongation) and is recommended where formability is critical.
- Bake hardenability: the ability to remain low in strength during machining; then strength is increased by the heat of coat-baking.
