aluminum sheet - strange mechanical properties

aluminum sheet - strange mechanical properties

(OP)
hi there,

Is it possible that aluminium sheet (4mm) has following properties:

290 MPa (Rm) and Elongation at the range of 26% or this is contrary?
There are no such values combined in any aluminum properties datasheets

this the results we've got from laboratory - did they make a mistake?

Why not? What is wrong?

to hard to be so flexible?...

RE: aluminum sheet - strange mechanical properties

5454-O typically is 250 MPa and 22 %, so it is possible to get there with material low in impurities.

You also need to know how the sheet was processed (stretch leveled?) and which direction was tested (L or T).
With sheet you should always have both directions tested.
