The 2A12 Aluminum Sheet is a high strength, heat treatable aluminum alloy sheet belonging to the 2000 series (also known as 2A12 or LY12 in some standards). This alloy provides an excellent balance of mechanical performance, machinability, and structural reliability, making it suitable for demanding engineering and industrial applications. Its primary alloying elements include copper (Cu) and magnesium (Mg), which enhance both strength and fatigue resistance.

Its primary alloying elements include copper (Cu) and magnesium (Mg), which enhance both strength and fatigue resistance.
This sheet alloy can be supplied in various tempers (statuses) — including O, T3, T4, T351 and H112 — to meet different performance requirements ranging from annealed to heat treated conditions. 2A12 aluminum exhibits high tensile and yield strength, good machinability, and moderate corrosion resistance (often improved by surface treatments).
Typical applications include aerospace structural components, automotive parts, high strength machinery elements, molds and dies, and other critical load bearing structural uses where strength and durability are essential.
