Is 2024-T4 the same as 2024 T351?
Both 2024-T351 aluminum and 2024-T4 aluminum are variants of the same material. They share alloy composition and many physical properties, but develop different mechanical properties as a result of different processing.
What is the difference between T351 and T3511?
-T351: Solution heat treatment and stress relieved by stretching. This is equivalent to -T4 condition. It applies to 2024 plate and rolled bar and 2219 plate per MIL-A-8920. -T3511: Solution heat treated and stress relieved by stretching with minor stretching allowed.
What is the core material of 2024-T4?
The core material of Alclad 2024-T4 is… heat-treated aluminum alloy, and the surface material is commercially pure aluminum.
What does T4 mean in aluminum?
T4 – Solution heat-treated and naturally aged. T5 – Artificially aged after cooling from an elevated temperature shaping process. T6 – Solution heat-treated and artificially aged. T7 – Solution heat-treated and stabilized (overaged).
What is 2024 T3 aluminum 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 does T351 mean?
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’s the difference between 2024 and T4 aluminum?
2024-T351 Aluminum vs. 2024-T4 Aluminum. Both 2024-T351 aluminum and 2024-T4 aluminum are variants of the same material. They share alloy composition and many physical properties, but develop different mechanical properties as a result of different processing.
What’s the difference between T4 and T351 aluminum?
We ordered 2024 aluminum round T4 temper. We called to ask what this means as we don’t follow AS9100. The explanation that we got was the T351 meets the requirements of T4 and then some. That T351 is stress relieved where T4 may or may not be.
Can a T351 be heat treated to a T4?
T351 can be heat treated to T4 by heating to 495±5C (time dependent on cross sectional thickness) and the either cold water or polymer quenched (again the delay time between heat treatment and quenching is dependent on thickness, but generally the quicker into the quench the better).
Can a T4 bar be used for a T351 bar?
The explanation that we got was the T351 meets the requirements of T4 and then some. That T351 is stress relieved where T4 may or may not be. Thus, if the actual physicals meet the ASTM requirement we can use T351 for our application as it has the same properties. My question is – did I understand this correctly?
