6063 aluminum alloy mechanical properties

Mechanical properties of 6063 aluminum alloy

The mechanical properties of 6063 aluminum alloy depend greatly on the temper, or heat treatment, of the material.

6063-O

Un-heat-treated 6063 has a maximum tensile strength of no more than 19,000 psi (131 Mpa) and no specified maximum yield strength.

The material has elongation (stretch before ultimate failure) of 18%.

6063-T1

T1 temper 6063 has an ultimate tensile strength of at least 17,000 psi (117 MPa) in thicknesses up to 0.5-inch (13 mm), and 16,000 psi (110 MPa) from 0.5 to 1.0-inch (25 mm) thick,

And yield strength of at least 9,000 psi (62 MPa) in thickness up to 0.5-inch (13 mm) and 8,000 psi (55 MPa) from 0.5 to 1.0-inch (25 mm) thick.

It has an elongation of 12%.

6063-T4

T4 temper 6063 has an ultimate tensile strength of at least 19,000 psi (131 MPa) in thicknesses up to 0.5-inch (13 mm), and 18,000 psi (124 MPa) from 0.5 to 1.0-inch (25 mm) thick,

And yield strength of at least 10,000 psi (69 MPa) up to 0.5-inch (13 mm) and 9,000 psi (62 MPa) from 0.5 to 1.0-inch (25 mm).

It has an elongation of 14%.

6063-T5

T5 temper 6063 has an ultimate tensile strength of at least 22,000 psi (152 MPa) in thicknesses up to 0.5-inch (13 mm), and 21,000 psi (145 MPa) from 0.5 to 1.0-inch (25 mm) thick,

And yield strength of at least 16,000 psi (110 MPa) up to 0.5-inch (13 mm) and 15,000 psi (103 MPa) (from 0.5 to 1.0-inch (25 mm).

It has an elongation of 8%.

6063-T6

T6 temper 6063 has an ultimate tensile strength of at least 30,000 psi (207 MPa)

And yield strength of at least 25,000 psi (172 MPa).

In thicknesses of 0.124-inch (3.1 mm) or less, it has elongation of 8% or more;

in thicker sections, it has elongation of 10%.

Other tempers

6063 is also produced in tempers T52, T53, T54, T55, and T832, with various improved properties.
