2024-T851 aluminum alloy is the 2024 aluminum alloy processed to the T851 condition. To achieve this condition, the aluminum alloy is first subjected to solution heat treatment, followed by stress relief treatment, and finally aging treatment.
Condition: T8510
Processing Steps:
Solution Heat Treatment: Heating the aluminum alloy at high temperatures to dissolve the alloying elements completely into the aluminum matrix.
Stress Relief: Releasing internal stress by stretching the metal to a certain extent. The stretching amount is determined based on the specific forged product type (e.g., extrusions or tubes).
Aging: Performed at a lower temperature to increase the strength and hardness of the aluminum alloy.
Characteristics: After stress relief, the metal does not get straightened, maintaining its original shape. The T8510 condition does not allow straightening compared to the T8511 condition, which permits straightening.
Condition: T8511
Processing Steps:
Solution Heat Treatment: Heating at high temperatures to dissolve the alloying elements.
Stress Relief: Releasing internal stress by stretching the metal. The stretching amount is determined based on the type of forged product (e.g., extrusions or tubes).
Aging: Performed at a lower temperature to enhance strength and hardness.
Characteristics: After stress relief and aging, the metal is straightened. This condition is closely related to the T8510 condition, which does not allow straightening.
Condition: T861
Processing Steps:
Solution Heat Treatment: Heating the aluminum alloy to high temperatures to dissolve the alloying elements.
Aging: Conducted at higher temperatures to achieve maximum strength and minimum ductility.
Characteristics: 2024-T861 aluminum offers the highest strength and lowest ductility compared to other 2024 aluminum alloy conditions, providing maximum strength performance.
1. Solution Heat Treatment
2. To release internal stresses generated during the solution heat treatment
3. Aging Treatment
Through these processing steps, 2024-T851 aluminum alloy can maintain good strength and hardness while ensuring performance stability in practical applications.
Is 2024 aluminum harder than 6061?
Yes, 2024 aluminum is generally harder and has higher strength compared to 6061.
What is the difference between 2024 and 7075 aluminum?
2024 aluminum offers higher strength and is more suitable for aerospace applications, while 7075 aluminum provides even higher strength and better resistance to stress-corrosion cracking.
What is 2024 aluminum grade?
2024 aluminum is an alloy primarily composed of aluminum and copper, known for its high strength and good fatigue resistance.
