Aluminum A1050 H24 vs. H14 Aluminum Plate: What Is the Difference?
Selecting the correct temper for a 1050 aluminum plate directly affects strength, formability, and processing efficiency. At GNEE, we support manufacturers and fabricators worldwide by providing clear material guidance alongside a reliable aluminum plate supply. This article explains the key differences between Aluminum A1050 H24 and H14 aluminum plates, helping you confidently choose the right option for your application.
Overview of Aluminum A1050 Aluminum Plate
Aluminum A1050 belongs to the 1xxx series of commercially pure aluminum, with an aluminum content of 99.50% or higher. It is well known for excellent corrosion resistance, high thermal and electrical conductivity, and outstanding workability. Since A1050 is a non-heat-treatable alloy, its mechanical properties are adjusted primarily through work hardening, indicated by the H temper designation.
Typical Chemical Composition of A1050 Aluminum Plate
| Element | Maximum Content (%) |
|---|---|
| Aluminum (Al) | ≥ 99.50 |
| Silicon (Si) | 0.25 |
| Iron (Fe) | 0.40 |
| Copper (Cu) | 0.05 |
| Other elements | 0.03 each |
Meaning of the H Temper in A1050 Aluminum Plate
In aluminum temper designations, "H" indicates a work-hardened condition. The digits following H describe how the material was processed and the final hardness level.
First digit (H1, H2, H3): Indicates the type of work hardening
H1: Strain hardened only
H2: Strain hardened and partially annealed
H3: Strain hardened and stabilized
Second digit (0–9): Indicates the degree of hardness
0: Fully annealed (soft)
8: Fully hard
1–7: Intermediate states
4: Semi-hard condition (commonly used)
Aluminum A1050 H14 Aluminum Plate Explained
A1050 H14 aluminum plate is produced through simple work hardening only, without any heat treatment.
The tensile strength reaches an intermediate level between fully annealed (H0) and fully hard (H18)
Provides a good balance of strength and formability
Suitable for applications requiring moderate forming and consistent surface quality
This temper is commonly selected when basic mechanical strength is sufficient and processing complexity is limited.
Aluminum A1050 H24 Aluminum Plate Explained
An A1050 H24 aluminum plate undergoes work hardening followed by partial annealing.
Partial annealing reduces internal stress
Improves ductility and forming stability
Maintains a semi-hard condition similar to H14, but with better uniformity
Because of this controlled process, H24 is often preferred for applications involving more demanding forming operations.
Aluminum A1050 H24 vs H14 Aluminum Plate: Key Differences
| Feature | A1050 H14 Aluminum Plate | A1050 H24 Aluminum Plate |
|---|---|---|
| Processing method | Cold worked only | Cold worked + partial annealing |
| Hardness level | Semi-hard | Semi-hard (more stable) |
| Internal stress | Relatively higher | Lower |
| Formability | Good | Better |
| Application complexity | Simple forming | Complex or deeper forming |
Mechanical Properties of A1050 Aluminum Plate (Typical)
| Temper | Tensile Strength (MPa) | Yield Strength (MPa) | Elongation (%) | Brinell Hardness (HB) |
|---|---|---|---|---|
| H14 | 95–135 | ≥ 70 | 3–8 | ~32 |
| H24 | 105–145 | ≥ 75 | 3–8 | ~33 |
Actual values may vary depending on thickness and production standards.
