2618A Aluminium Alloy (Aluminium 2618)

2618A Aluminium Alloy (Aluminium 2618)

2618A aluminium  (aluminium 2618) is a highly ductile and strong aluminium alloy which contains both copper and magnesium. Alloy 2618A features good corrosion resistance, good machinability and the ability to absorb a large amount of extreme heat, while taking minimal damage.  These properties make aluminium alloy 2618A (aluminium 2618) an excellent metal to use in aerospace and defence components and in high performance autosport applications.

2618A aluminium can be welded using resistance welding techniques. 2618 alloy can be heat treated at 530°C (985°F) for a sufficient period followed by quenching in water. Aluminum 2618 alloy is forged at 372 to 522°C (700 to 970°F). This alloy is hot worked at 350 to 372°C (660 to 700°F) and can be cold worked in the heat treated or annealed conditions. Annealing can be performed at 385°C (725°F) for 4 h.

Aluminium Alloy 2618A (Aluminium 2618) is available in Plate, Bar, Rod, Sheet, Forging Stock and Tube.
