3.1645 AlCuMgPb Material?

[crunchie12268]

Hello,

I have a drawing from Germany with this material called out "3.1645 AlCuMgPb". I am wondering what this would be comprable to? The International Registration Record (AA) U.S.A. Specs calls this a "2007" material? Any help would be appreciated.

It's a 2000 series aluminum alloy with the following chemical composition limits in weight percent:

Cu 3.3 - 4.6
Fe 0.8 Max
Mg 0.4 - 1.8
Mn 0.10 Max
Si 0.8 Max
Ti 0.20 Max
Zn 0.8 Max

Balance is aluminum.
