MATERIAL PROPERTIES OF ALUMINUM 7075 PLATE AND SHEET

Aluminum 7075 sheet, plate, clad sheet and clad plate mechanical properties at room-temperature for T6 / T651 / T73 / T7351 / T76 / T7651 tempers.

Notes:

• e - edge distance (measured in the loading direction), D - diameter of the hole
• Bearing strengths are given without reference to direction and may be assumed to be about the same in all directions A reduction factor is used for edgewise bearing load in thick bare and clad plate of 7000 series alloys. See MMPDS-01 for % of reductions.nce to direction and may be assumed to be about the same in all directions A reduction factor is used for edgewise bearing load in thick bare and clad plate of 7000 series alloys.

• Caution - 7075-T651 plate exhibits poor stress-corrosion cracking resistance in ST grain direction.
• In those instances where the direction in which the material will be used is not known, the lesser of the applicable longitudinal or transverse properties should be used.
• Clad aluminum alloys may have two separate modulus of elasticity values. Primary modulus is the response of both the low-strength cladding and higher-strength core elastic behaviors. This value applies only up to the proportional limit of the cladding. Above the proportional limits of cladding materials, a short transition range occurs while the cladding is developing plastic behavior. The material then exhibits a secondary elastic modulus up to the proportional limit of the core material.

Definitions:

A Basis: The lower value of either the statistically calculated number T99, or the specification minimum (S-basis). T99 indicates that at least 99 percent of the population is expected to equal or exceed the statistically calculated mechanical property value with a confidence of 95 percent.

S Basis: S-values are minimum values given in the material specifications and standards. Their statistical bases are not defined.

Clad: Sheets and plates are clad with high purity aluminum in order to increase the resistance to corrosion of the bare material.

Longitudinal Direction: Direction parallel to the flow in a worked material (grain direction).

Long Transverse: Transverse direction having the largest dimension (width direction).

Short Transverse: Transverse direction having the smallest dimension (thickness direction)

Solution heat treatment: Heating the alloy to a suitable temperature, waiting at that temperature long enough to allow constituents to dissolve and rapid cooling to hold the constituents in solution.

Modulus of elasticity (Young’s modulus): The rate of change of unit tensile or compressive stress with respect to unit tensile or compressive strain for the condition of uniaxial stress within the proportional limit.

Poisson’s ratio: The ratio of lateral unit strain to longitudinal unit strain under the condition of uniform and uniaxial longitudinal stress within the proportional limit.

Shear stress: A form of a stress acts parallel to the surface (cross section) which has a cutting nature.

Stress: Average force per unit area which results strain of material.
