The new, casting friendly, Alcoa EZCast-NHT™ A152 non-heat-treatable alloy makes it possible to use parts in their “as-cast” state, eliminating two costly process steps -- heat treatment and straightening – while yielding required mechanical properties. The new alloy is suited for complex thin-wall castings for various car body structures for both conventional and electrified vehicles. It also offers good revitability with SPRs and good weldability.
