ALUMINUM ALLOY 2024 GENERAL DESCRIPTION:
What is Alloy 2024?
2024 aluminum is heat-treatable aluminum alloy with copper as the primary alloying element. It is malleable when in the fully soft, annealed temper and can be heat-treated to high strength levels after forming. Due to its high strength to weight ratio, it is widely used in aerospace applications.
CHEMICAL COMPOSITION LIMITS:
