The following typical properties are not guaranteed, since in most cases they are averages for various sizes, product forms, and methods of manufacture and may
not be exactly representative of any particular product or size. These data are intended only as a basis for comparing alloys and tempers and should not be specified
as engineering requirements or used for design purposes.

Eutectic melting can be completely eliminated by homogenization.

Eutectic melting is not eliminated by homogenization.

Homogenization may raise eutectic melting temperature 20–40°F but usually does not eliminate eutectic melting.

Although not formerly registered, the literature and some specifications have used T736 as the designation for this temper.

Fatigue strength
Mechanical properties are a function of the alloy and temper as well
as, in some cases, product form. For example, 6061-T6 extrusions have
a minimum tensile ultimate strength of 38 ksi (260 MPa), while 6061-
T6 sheet and plate have a minimum tensile ultimate strength of 42 ksi
(290 MPa).
2.4.1 Minimum and Typical Mechanical Properties
There are several bases for mechanical properties. A typical property
is an average property; if you test enough samples, the average of the
test results will equal the typical property. A minimum property is de-
fined by the aluminum industry as the value that 99% of samples will
equal or exceed with a probability of 95%. (The U.S. military calls such
minimum values “A” values and also defines “B” values as those for
which 90% of samples will equal or exceed with a probability of 95%, a
slightly less stringent criterion that yields higher values). Typical me-
chanical properties are given in Table 2.17. Some minimum mechani-
cal properties are given in ASTM and other specifications; more are
given in Table 2.18 for wrought alloys and Table 2.19 for cast alloys.
Minimum mechanical properties are called “guaranteed” when prod-
uct specifications require them to be met, and they are called “ex-
pected” when they are not required by product specifications.
Structural design of aluminum components is usually based on min-
imum strengths. The rules for such design are given in the Aluminum
Association’s Specification for Aluminum Structures, part of the Alu-
minum Design Manual. Safety factors given there, varying from 1.65
to 2.64 by type of structure, type of failure (yielding or fracture), and
type of component (member or connection), are applied to the mini-
mum strengths to determine the safe capacity of a component. Typical
strengths should be used to determine the capacity of fabrication
equipment (for example, the force required to shear a piece) or the
strength of parts designed to fail at a given force to preclude failure of
an entire structure. (Pressure relieving panels are an example of this,
called frangible design). Maximum ultimate strengths are specified for
some aluminum products (usually in softer tempers), but these mate-
rials are usually intended to be cold worked into final use products,
changing their strength.

The typical properties listed in this table are not guaranteed, since in most cases they are averages for various sizes, product forms, and
methods of manufacture and may not be exactly representative of any particular product or size. These data are intended only as a basis
for comparing alloys and tempers and should not be used for design purposes.
2
The indicated typical mechanical properties for all except 0 temper material are higher than the specified minimum properties. For 0
temper products typical ultimate and yield values are slightly lower than specified (maximum) values.
3
Based on 500,000,000 cycles of completely reversed stress using the R.R. Moore type of machine and specimen.
4
Average of tension and compression moduli. Compression modulus is about 2% greater than tension modulus.
5
1350-O wire will have an elongation of approximately 23% in 10 inches.
6
1350-H19 wire will have an elongation of approximately 1.5% in 10 inches.
7
Tempers T361 and T861 were formerly designated T36 and T86, respectively.
8
Based on 10
7
cycles using flexural type testing of sheet specimens.
9
Based on 1/4 in thick specimen.

T7451, although not previously registered, has appeared in literature and in some specifications such as T73651.

1
Values represent properties obtained from separately cast test bars and are derived from ASTM B-26, Standard Specification for Aluminum-
Alloy Sand Castings; Federal Specification QQ-A-601e, Aluminum Alloy Sand Castings; and Military Specification MIL-A-21180c, Aluminum
Alloy Castings, High Strength. Unless otherwise specified, the average tensile strength, average yield strength, and average elongation values
of specimens cut from castings shall be not less than 75 percent of the tensile and yield strength values and not less than 25 percent of the
elongation values given above. The customer should keep in mind that (1) some foundries may offer additional tempers for the above alloys,
and (2) foundries are constantly improving casting techniques and, as a result, some may offer minimum properties in excess of the above.
2
Hardness values are given for information only; not required for acceptance.
3
F indicates “as cast” condition; refer to AA-CS-M11 for recommended times and temperatures of heat treatment for other tempers to achieve
properties specified.
4
Mechanical properties for these alloys depend on the casting process. For further information, consult the individual foundries.
5
The T4 temper of Alloy 520.0 is unstable; significant room temperature aging occurs within life expectancy of most castings. Elongation may
decrease by as much as 80 percent.
