2024-T3 ALCLAD Aluminum
In 2024 Copper is the main alloying ingredient. It is very strong compared to most aluminum alloys and has average machinability. The copper component of this alloy makes it susceptible to corrosion; many items in this alloy are produced with a clad surface to protect the underlying material. In addition, 2024 is not considered to be a weldable alloy.
