Changing Material Doesn't effect "press limit" in limit diagram

I am trying to compare the possible extrusion speeds for several aluminum alloys. However, changing the material seems has no impact on the "press limit" curve. Even when comparing 6063 to a 5000 series, the curve stays exactly the same. This cannot be correct. Is this a common problem?

Hello Jacob,

Limit diagram is plotted based on profile shape, material and press that you have selected.

Go to second tab "Model Data", confirm if material and press data are selected as per your selection.

if it is not showing your material and press ID, then click on Reset button on bottom of the panel.

Thanks,

Hello Narendra,

Thank you for your response. However, I don't think I explained the problem clearly enough. Even after changing the material and clicking reset the plots stay exactly the same. I attached some screenshots so you can see what I mean. The AA5182 should be much more difficult to extrude than the 6063, yet the diagrams are identical.

Thank you,

Jacob
