Description

Alloy AlCu2MgNi (AlCuMgFeNi) is an especially for aircraft construction modified alloy of type AlCuMg. Beside 2,5 % Cu it contains 1,5 % Mg as well as 1,1 % Fe and Ni. It is a natural and artificial ageable, high-strength alloy and achieves tensile strength values up to 430MPa at A5-ductile yiled of 3 to 8%. Heat-resistance properties of this alloy are enhancable by Fe- and Ni-content what represents the dominating application attribute. Heat-treatment instructions have to be most accurately adhered in order to warrant high heat-strength up to 250 deg. C. Usual semi-finished forms are thick plates, rods as well as die and free-form forged parts. This material has a high machinability, anodizability and hot-workability. It is cold-workable in soft condition resp. 2 h after solution annealing only. The alloy is not suitable for welding. Its corrosion resistance is satisfactory only. Application: in aircraft construction for large structure and power plant parts.
