Is 6061 aluminum heat treated?
6061 aluminum is a ductile metal that can be stamped, cut, deep drawn, drilled, tapped, bent, welded, hydroformed and more. Magnesium and silicon are the major alloying elements in this metal, and 6061 is generally strong and corrosion resistant. It is heat treatable and crack resistant when stress is removed.
How strong is Aluminium 6061?
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%.
Is 6061 aluminum ductile or brittle?
(2) Both 5052 and 6061 aluminum alloys are subject to a mixed ductile fracture and brittle fracture; ductile fracture plays the main role for the AA5052, whereas brittle fracture plays a major role for the AA6061.
How do you harden 6061?
Aluminium / Aluminum 6061 alloy is heat-treated at 533°C (990°F) for a sufficient period of time followed by quenching in water. The precipitation hardening process can be performed at 160°C (320°F) for 18 h followed by air cooling. This process is again repeated at 177°C (350°F) for 8 h followed by cooling in air.
How strong is aircraft grade aluminum?
A high-grade alloy with excellent fatigue resistance, 2024 is used primarily in sheet forms such as for the fuselage and wings due to its high tensile strength of roughly 470MPa. Of the non-heat treatable grades of alloy, 5052 provides the highest strength and is highly ductile, so it can be formed into various shapes.
CAN 6061-T6 be welded?
The base alloy referenced in the above question, 6061-T6 for instance, is commonly welded with at least four totally different filler alloys and can be welded successfully with even more.
What are the properties of 6061 temper aluminum?
Material Properties of 6061-T4 and 6061-T6 Aluminum. Generally, 6061 aluminum is solution heat treated, then aged. T4 temper aluminum is naturally aged, and T6 temper aluminum is artificially aged for maximum strength.
What is the thermal conductivity of 6061 aluminium?
The thermal conductivity of 6061 aluminium alloy is 150 W/ (m.K). The heat transfer characteristics of a solid material are measured by a property called the thermal conductivity, k (or λ), measured in W/m.K.
How is 6061 aluminum heat treated and aged?
Generally, 6061 aluminum is solution heat treated, then aged. T4 temper aluminum is naturally aged, and T6 temper aluminum is artificially aged for maximum strength. Here we can see the density of the alloy.
What is the yield strength of T4 temper 6061?
T4 temper 6061 has an ultimate tensile strength of at least 180 MPa (26 ksi) or 210 MPa (30 ksi) and yield strength of at least 110 MPa (16 ksi). It has elongation of 10-16%. T6 temper 6061 has been treated to provide the maximum precipitation hardening (and therefore maximum yield strength) for a 6061 aluminum alloy.
