What is the difference between 6061 T6 and 7075-T6 aluminum?
6061 nearly always has the edge over 7075 when it comes to fabricating the two aluminum alloy types. This is mostly due to 6061 having a lower hardness and tensile strength. The lower hardness allows it to be machined more easily than 7075. The lower tensile strength means that 6061 is easier to form than 7075.
What is the difference between 7075-T6 and 7075?
7075 contains zinc as the primary alloy addition and possesses excellent fatigue properties. However, in the T6 temper its fracture toughness can be inferior to other alloy choices. It has excellent mechanical properties, and exhibits good ductility, high strength, toughness and good fatigue resistance.
How strong is 6061 T6 aluminum?
6061-T6. T6 temper 6061 has an ultimate tensile strength of at least 42,000 psi (290 MPa) and yield strength of at least 35,000 psi (241 MPa). In thicknesses of 0.250 inch (6.35 mm) or less, it has elongation of 8% or more; in thicker sections, it has elongation of 10%.
Can you harden 6061 aluminum?
6061-T4 aluminum is part way to the hardest that this aluminum alloy can be. The aluminum hardening process can be stopped by placing aluminum parts in a freezer until they’re ready to be hit on the press again. After this secondary pressing, the parts go through an aging heat treatment process.
What is 7075 aluminum alloy used for?
Uses. 7075 is widely used for construction of aircraft structures, such as wings and fuselages. Its strength and light weight are also desirable in other fields. Rock climbing equipment and bicycle components are commonly made from 7075 aluminium alloy.
How do you heat treat 7075 aluminum?
HEAT TREATING 7075 may be solution annealed at 900°F for 2 hours at temperature, followed by a water quench. The alloy may then be given a precipation hardening (aging) heat treatment. Precipitation strengthening (aging) is done at 250°F for 24 hours and air cooled for T6.
