Nor going with the grain.
Bending 2024-T6 requires proper set back and bend allowance for the desired
radius and bend degree.
Bend allowance depends on; the degree of bend, the radius of bend, the
material thickness and the type of material.

Alclad or Pureclad are both terms to designate metal sheets that have a
aluminum core coated with a layer of pure aluminum on one or both sides.
The thickness of the pure aluminum coating depends on the thickness of the
sheet. The nominal Alclad thickness is 4% of the complete thickness for
material under 0.063 of an inch; 2.5% for material in the range of 0.063 to
0.187 inch, and 1.5% for material 0.188 inch and thicker.
