Copper Alloy (Al-Cu). AA designation 2519.
Overview
AA 2519 is an aluminium–copper–magnesium alloy developed for military armour, offering good ballistic resistance together with weldability uncommon among high-strength 2xxx grades. Roughly 5.3–6.4% copper, with manganese and zirconium additions, contributes both to high strength and to spall resistance. The alloy is used in armoured-vehicle hulls, combat-vehicle panels, and other protective military structures.

説明
AA 2519 is an aluminum-copper-magnesium alloy developed for military armor applications, providing good ballistic resistance combined with weldability not typical of high-strength 2xxx alloys. It contains approximately 5.3–6.4% copper with additions of manganese and zirconium that contribute to high strength and spall resistance. The alloy is used in armored vehicle hulls, combat vehicle panels, and military equipment structures.
