4. Detailed Application Areas
-
Used to increase strength and hardness in aluminum alloys.
-
Copper forms soluble phases in aluminum, enabling age hardening (precipitation hardening).
-
Commonly used in AlCu series alloys (e.g., 2xxx series).
-
Application areas include:
-
Aircraft structures, automotive chassis components, defense-grade aluminum parts
-
High-temperature and high-stress aluminum applications
-
-
Added directly into molten aluminum to achieve target Cu concentration.
5. Mandatory Use Cases
-
Aerospace and defense sectors require Cu addition for high-strength aluminum alloys.
-
Compliance with standards such as EN 573, AMS 4027, ASTM B209 may necessitate AlCu master alloy usage.
