Amsterdam, The Netherlands – Aluminum producer Constellium N.V. has introduced a new generation of high-strength 6000-series alloys, Constellium HSA6. The alloys are already in production for several 2017 and 2018 model year vehicles, including the Mini Countryman.
Designed for extrusion-based crash-management systems, body-in-white structural components, and battery enclosures, HSA6 allows designers to reduce wall thickness to reduce weight by 15% to 30% compared to conventional aluminum alloys. With ultimate tensile strength (UTS) higher than 400MPa, Constellium HSA6 provides recyclability, machinability, and corrosion resistance.
Alternately, using the alloy can boost component strength by 15% to 30%.
According to a new study by Ducker Worldwide, aluminum extrusions are expected to increase 65% for crash management systems and double for body-in-white components between 2015 and 2020, with continued growth through 2028.
