Constellium intoduces alloys for automotive components
Constellium has introduced a new generation of high-strength 6000-series alloys, Constellium HSA6TM, to help automakers meet growing demand for lighter weight vehicles. Constellium HSA6TM is in production for several 2017 and 2018 model year vehicles, including the MINI Countryman. Ideal for extrusion-based Crash Management Systems, Body-in-White structural components and battery enclosures, Constellium HSA6TM allows designers to optimize extrusion shapes and reduce wall thickness to achieve weight savings of 15-30% compared to conventional aluminium alloys. With ultimate tensile strength higher than 400MPa, Constellium HSA6TM also provides enhanced recyclability, machinability and corrosion resistance.Alternately, Constellium HSA6TM can provide 15-30% additional strength to reduce intrusion in the event of a crash, thereby enhancing protection of batteries, cooling systems and other critical vehicle systems. Aluminium is the ideal material for absorbing energy in a collision to protect occupants, pedestrians and vehicle integrity. "With Constellium HSA6TM, we are able to offer automakers a family of the highest strength 6000-series aluminium alloys available on the market for extruded automotive components," said Martin Jarrett, Operational Excellence and Technology Director for Constellium's Automotive Structures and Industry business unit.
