Abstract

The investigation results of the new weldable wrought alloy V-1208 based on Al–Cu–Mn system with addition of Sc, Ag and Zr are represented. Sheets from this alloy were manufactured at JSC «KUMW». It was shown that scandium, silver and zirconium complex additions increase strength and life-time characteristics, corrosion resistance and weldability. Influence of heat treatment modes on the sheets mechanical properties was studied. Complex investigations of mechanical, corrosion and operational charac-teristics are represented. Weldability with argon arc welding and friction stir welding are evaluated. Comparison with 1201 and 2219 alloys is carried out.
