Alclad 2024 O T3 T4 Aluminum Sheet
2024 is one of the most well-known high-strength aluminum alloys, often referred to as the "aircraft" alloy due to its exceptional strength. 2024 aluminum sheets possess excellent machinability and can be processed to achieve a high degree of polish.
Due to its relatively lower corrosion resistance, 2024 aluminum alloy is typically treated with anodization or provided in a composite form known as "Alclad," featuring a thin layer of high-purity aluminum on its surface. This treatment enhances fracture toughness and fatigue crack propagation while preserving the strength characteristics of the alloy.
