What is the hardness of 2024 aluminum?
Aluminum 2024-T4; 2024-T351
| Physical Properties | Metric | English |
|---|---|---|
| Hardness, Rockwell B | 75 | 75 |
| Hardness, Vickers | 137 | 137 |
| Ultimate Tensile Strength | 469 MPa | 68000 psi |
| Tensile Yield Strength | 324 MPa | 47000 psi |
What is the difference between 2024 T4 and 2024 T351?
The difference: after quenching, the T351 rod was stress relieved by stretching 1-3% prior to aging. Thus, T351 is more stable for machining, as T4 still has residual stresses from quenching: compressive near the surface and tension in the center. T4 is perhaps better in some fatigue applications.
What is 2024 Aluminium alloy used for?
Uses. Due to its high strength and fatigue resistance, 2024 is widely used in aircraft, especially wing and fuselage structures under tension. Additionally, since the material is susceptible to thermal shock, 2024 is used in qualification of liquid penetrant tests outside of normal temperature ranges.
What is the difference between 2024 and 7075 aluminum?
Probably one of the most common aluminum alloys being used, 2024 displays high strength and good workability and formability. 7075, on the other hand, is one of the strongest aluminum alloys available and 7075 alloys are worth the typically higher cost when strength and toughness are crucial.
What is the difference between 6061 and 7075 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 T4 heat treatment?
T4 – Solution heat treated, and naturally aged to a substantially stable condition. T5 – Cooled from an elevated temperature shaping process then artificially aged. T6 – Solution heat treated then artificially aged. T10 – Cooled from an elevated temperature shaping process, cold worked, then artificially aged.
How do you anneal 2024?
Annealing is done at 750°-800°F for at least 2 hours at temperature, followed by slow cooling in furnace. This will anneal 2024 from a heat treated condition. Annealing 2024 between cold working operations may be done at 650°F for 2 hours, followed by air cool.
What metals does a 2024 T4 alloy contain?
| Physical Properties | Metric | English |
|---|---|---|
| Aluminum, Al | 90.7 – 94.7 % | 90.7 – 94.7 % |
| Chromium, Cr | <= 0.10 % | <= 0.10 % |
| Copper, Cu | 3.8 – 4.9 % | 3.8 – 4.9 % |
| Iron, Fe | <= 0.50 % | <= 0.50 % |
What does the 0 in 2024-T3 mean?
2024-T3 means aluminum of type 2024 with a T-3 temper. Aluminums in the 2xxx series are aluminum-copper alloys, and 2024 is one specific composition. T-3 means solution heat treated and cold worked.
What kind of temper does 2024 t3510 have?
2024-T3510 aluminum is 2024 aluminum in the T3510 temper. To achieve this temper, the metal is solution heat-treated, stress relieved, then naturally aged. The stress relief is accomplished by stretching the metal by an amount that depends on the type of standard wrought product being made (extrusion or tube).

What’s the difference between T4 and T351 finish?
T351 means “solution heat-treated, stress relieved through controlled stretching and naturally age hardened. The products are not straightened after stretching”. T4 means “solution heat-treated and naturally age hardened”.
What are the characteristics of the material 2024?
General 2024 characteristics and uses (from Alcoa): Good machinability and surface finish capabilities. A high strength material of adequate workability. Has largely superseded 2017 for structural applications.
