Hi, I am looking for some mechanical properties (Ftu, Fty, Fcy, Fsu, Fbru, etc.) for L164 Aluminum, T4 temper. I found some cross references for L164 aluminum to 2014 aluminum online, but when I check MMPDS-01, T4 is not a typical temper for 2014 aluminum. So, I'm not sure what the true mechanical properties are for L124. We're working on a lower wing skin repair on a Britten-Norman Islander aircraft (used as a crop duster here down south) that is apparently made of the L164 material, but we have no data for the material. Any thoughts?

Thanks, yes, I had found that, too. I was kind of looking for more of an "apples to apples" type comparison with respect to all the mechanical properties usually gleaned from MMPDS-01 (Ftu, Fty, Fcy, Fsu, Fbru, etc.) but I'm not sure where to find it.
 
The L164 specification is a British Standards Aerospace call out with the full specification being BS L 164 and is titled;

"Sheet and Strip of Aluminium-Coated Aluminium- Copper- Magnesium-Silicon- Manganese Alloy (Solution Treated and Aged at Room Temperature) (Cu 4.4, Mg 0.5, Si 0.8, Mn 0.8)"

It should have properties in the ESDU Metallic Materials Data Handbook,
 
That link goes to a 3 page intro document and not the full handbook. Do you have the link for that?
 
Use the contact list at the bottom- you'll probably have to buy access.
