T7 temper has an ultimate tensile strength of 505 MPa (73,200 psi) and yield strength of 435 MPa (63,100 psi). It has a failure elongation of 13%. T7 temper is achieved by averaging (meaning aging past the peak hardness) the material. This is often accomplished by aging at 100–120 °C for several hours and then at 160–180 °C for 24 hours or more. The T7 temper produces a microstructure of mostly eta precipitates. In contrast to the T6 temper, these eta particles are much larger and prefer growth along the grain boundaries. This reduces the susceptibility to stress corrosion cracking. T7 temper is equivalent to T73 temper.
Let us now look at some of the different composition of 7075 T7351 Aluminium Sheets in Details:
|Hardness, Brinell||135||135||500 kg load with 10 mm ball. Calculated value.|
|Hardness, Knoop||120||120||Converted from Brinell Hardness Value|
|Hardness, Rockwell A||50.5||50.5||Converted from Brinell Hardness Value|
|Hardness, Rockwell B||82||82||Converted from Brinell Hardness Value|
|Hardness, Vickers||155||155||Converted from Brinell Hardness Value|
|Tensile Strength, Ultimate||73200 psi|
|Tensile Strength, Yield||63100 psi|
|Elongation at Break||13 %||In 5 cm; Sample 1.6 mm thick|

Alloy 7075 is the aerospace baseline metal with a good balance of properties required for aerospace applications.it is a high strength alloy using the beneficial effects of the alloying addition of chromium to develop good stress-corrosion cracking resistance in sheet products. These values have been used as a standard for comparison in the development of more recent high strength aerospace alloys and used for highly stressed structural parts in the aerospace and defense industries, and as mold material in the plastics industry. The main application and uses for Aluminum alloy 7075-T7351 are Aircraft fittings, gears and shafts, fuse parts, meter shafts and gears, missile parts, regulating valve parts, worm gears, keys, aircraft, aerospace and defense applications.
