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 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.
Why is 2024 aluminum known for its strength?
This breakdown explains why 2024 aluminum is known for its high strength because copper, magnesium, and manganese greatly increase the strength of aluminum alloys. This strength comes at a disadvantage, however; the high percentage of copper in 2024 aluminum greatly reduces its resistance to corrosion.
What are the special features of en aw-2024?
Chemical composition of EN AW-2024 3. Main application / Special features of EN AW-2024: A resilient material with increased strength values, which is mainly used in the aerospace industry. Use at elevated operating temperatures above 120 ° b is 180 ° C.
What does the 4 temper mean on 2024 aluminum?
For example, in the 2024-T42 temper, the “4” indicates that the alloy is strengthened with solution heat-treating and natural aging, but the “2” indicates that the buyer must heat-treat the metal themselves.
What can you do with a 2024 aluminum bar?
Machinability is good in heat treated and annealed condition. Commonly used in aircraft structural components, truck wheels, medical instruments, and screw machine products. We stock 2024-T351, 2024-T3511, and 2024-T4.
