For sale are 4 sheets of Alcoa 6013-T4 aluminum measuring 48" wide, 72" long, and 0.032" thick .. surplus from another project.
This is a hard-to-find, premium grade weldable material.
It is more formable in the -T4 temper.
After forming and/or welding, you can artificially age it up to -T6 temper in an oven.. ~350 F.
6013-T6 is significantly higher in yield & ultimate strength than 6061-T6 .. it's comparable in strength to 2024-T3, yet tougher and more corrosion resistant.
See manufacturer's spec sheet & pictures below.
Will sell all 4 sheets for $400.
Buyer pays shipping, or can pick up in Salt Lake City area.

6013 is good stuff. It's what the Questair Venture is made of, for example. If it weren't for price, I think we'd see a big move from 6061-T6 to 6013-T6 for many kits.

The 0.032" thick 6013-T4 sheet material is still available.
Price reduced to $250 for all 4 sheets, 48"x72".
I also have 3 cylinders rolled from these same sheets, 48" long x 20" diameter.

$150 for those.

Ref. Post 1
Artificially aging (precipitation heat treatment) in an oven requires first a solution heat treatment at 970°F and quick quench in cold water.
True, but these sheets are supplied in the -T4 temper which means they have already been solution treated, quenched, and naturally aged.
Artificial aging from relatively soft naturally aged -T4 temper to the fully hard -T6 temper only requires a 350 F oven for a few hours.
However, if you heat it to ~600 F or higher, as you will if you weld it, it turns into the soft "annealed" condition, with -O temper designation.
The only way to get full -T6 properties after welding is to go through the entire solution-quench-aging process sequence again.

Does that naturally aged T4 condition continue to age harden after delivery these past 8 years?
Probably somewhat.. sorry to be non-specific.
I've been told by aluminum suppliers that if you leave -T4 aluminum out in the hot summer sun for years, it can become less workable, though probably still more ductile than -T6.
It's a time-temperature variable range of properties
These -T4 sheets have been stored indoors, out of the sun, not always climate-controlled, but in a relatively cool climate with A/C in the summer.
I don't think they are significantly less workable than a fresh lot.
