Aluminum 7050 has very high mechanical
properties, high fracture toughness, along with a high resistance to exfoliation
and stress corrosion cracking.
Applications: Aluminum 7050 is typically used
in aircraft structural parts.

Chemical Composition Limits
The 7050 alloy may be readily formed in either the O temper or the heat
Welding of 7050 alloy is a problem and should be avoided. Gas tungsten or gas
metal arc welding is NOT successful with this alloy. Weld cracking and
porosity usually result and any weld joint that is made is much weaker than
the parent metal.
Solution heat treat at 890 F. Time at temperature is dependent upon section
thickness and the producer of the alloy should be consulted on this as well as
The alloy may be forged. However no data is available without consulting the
As with Forging the 7050 alloy may be hot worked but no data is available
except from the alloy producer.
The alloy may be cold formed by conventional means. However bend radii should
A 2 stage heat treatment is used for aging this alloy. First heat to 250 F for
3 to 6 hours (depending on section size) and follow that with 325 F for 15
hours then air cool.
Hardens only by precipitation heat treatment. See "Aging".
