The 6xxx series aluminium alloys after artificial ageing is going to be done to improve the mechanical properties are similar to Aluminium-Copper such alloys introduced to plane.
When the 6xxx series aluminium alloys used to make artificial ageing to improve the mechanical properties are similar. Aluminium-Copper alloys suitable for the aircraft.
The 6xxx series aluminium alloys when make artificial ageing will improve mechanical properties similar to Aluminium-Copper. Alloys suitable for applying to do the plane.
