3105 h24 aluminum sheet plate

3105 H24 aluminum is a treatment state of 3105 aluminum alloy, where "H24" indicates that the metal has undergone strain hardening and partial annealing.

What is 3105 grade aluminum?

3105 grade aluminum is an alloy in the 3000 series, known for its excellent combination of strength, formability, and corrosion resistance. It is a versatile alloy, renowned for its good strength, excellent corrosion resistance, and ease of fabrication, making it suitable for a wide range of industrial and consumer applications.

What is H24 in aluminum?

H24 Temper: 3105 aluminum alloy undergoes strain hardening followed by partial annealing.
Strain Hardening: Cold working increases the hardness and strength of 3105 aluminum alloy.
Partial Annealing: Heat treatment reduces hardness and improves ductility, making the alloy's properties intermediate between fully annealed (O) and fully hardened (H28) states.

3105 H24 aluminum properties

Strength Range: The strength of 3105-H24 aluminum alloy falls between the annealed state (O) and the fully hardened state (H28).
Hardness Characteristics: Provides moderate strength and rigidity, higher than the annealed state (O) but lower than the fully hardened state (H28).
Strength and Rigidity: Exhibits high strength and rigidity after strain hardening and partial annealing.
Ductility: Compared to the fully hardened state, the H24 temper retains better ductility, making it suitable for machining and forming.
Corrosion Resistance: 3105-H24 aluminum alloy has good corrosion resistance, suitable for use in various environments.
Machinability: Offers good machinability, suitable for applications requiring moderate strength and good machinability.

Property	3105-H14 Aluminum Alloy	3105-H24 Aluminum Alloy
Processing and Temper	Processing: Achieved through cold working (strain hardening) without subsequent annealing. Temper: Strain hardened to increase strength and hardness while maintaining good formability.	Processing: Involves strain hardening and partial annealing. Temper: After strain hardening, partial annealing reduces some hardness and improves ductility.
Formability and Fabrication	Formability: Good, but lower than H24. Applications: Suitable for applications requiring higher strength and stiffness but still needing a certain degree of formability.	Formability: Better formability and ductility compared to H14. Applications: Well-suited for applications where forming and shaping are crucial, such as manufacturing complex shapes or components.
Main Characteristics	Strength-to-Weight Ratio: Higher than H24. Machinability: Poorer ductility limits use in highly complex or precise forming processes.	Strength-to-Weight Ratio: Lower than H14, but still suitable for many applications. Machinability: Improved ductility makes it more suitable for applications requiring extensive forming and shaping.
