Семейство: Aluminum Alloy
Copper Alloy (Al-Cu). AA designation 2014.
Overview
AA 2014 is a high-strength aluminium–copper alloy carrying 3.9–5.0% copper with silicon, manganese, and magnesium that give it a strong precipitation-hardening response in the T6 temper. It reaches some of the highest strength levels available in aluminium, but shares the lower corrosion resistance typical of copper-bearing 2xxx grades. Where strength dominates the design, it appears in aircraft structural members, forgings, truck frames, and heavy-duty machine parts.

Описание
AA 2014 is a high-strength aluminum-copper alloy (3.9–5.0% Cu) with additions of silicon, manganese, and magnesium that provide precipitation hardening response in the T6 temper. It offers one of the highest strength levels of any aluminum alloy but has lower corrosion resistance than most other series. Applications include aircraft structural components, forgings, truck frames, and heavy-duty machine parts.
