Designation
Description
Alloy 1161 applies: for the production of high-strength extruded semifinished products (panels, profiles) and details of the power elements of the aircraft.
Note
The alloy system Al-Cu-Mg-Zr.
Standards
Chemical composition
Al is the base.
According to OST 1 90048-90 the total mass fraction of other impurities is ≤ 0.10%. When manufacturing compressed semi-finished products (panels and profiles) from alloy 1161, the content of alloy elements is set as follows: copper - 3.35-3.85%, magnesium - 1.40-1.80%, manganese - 0.40-0.70, zirconium - 0,08-0,16%, titanium 0,03-0,07%, silicon - not more than 0,050%.
