Aluminum A1050 H24 vs H14 Aluminum Plate: Key Differences Explained
Choosing the right temper for a 1050 aluminum plate can significantly affect forming performance, strength, and end-use durability. At GNEE, we help global customers select the most suitable aluminum alloy and temper for their applications. This article provides a clear comparison between Aluminum A1050 H24 and H14 aluminum plates, helping you make an informed decision with confidence.
Understanding Aluminum A1050 Aluminum Plate
Aluminum A1050 is a commercially pure aluminum alloy with a minimum aluminum content of 99.50%. It is widely valued for its excellent corrosion resistance, high electrical and thermal conductivity, and good workability. Because it is non-heat-treatable, its mechanical properties are mainly adjusted through work hardening, which is indicated by the "H" temper designation.
Aluminum A1050 Chemical Composition (Typical)
| Element | Content (%) |
|---|---|
| Aluminum (Al) | ≥ 99.50 |
| Silicon (Si) | ≤ 0.25 |
| Iron (Fe) | ≤ 0.40 |
| Copper (Cu) | ≤ 0.05 |
| Others (each) | ≤ 0.03 |
What Does H14 Mean in A1050 H14 Aluminum Plate?
The H14 temper refers to a strain-hardened, half-hard condition achieved only through cold working, without any additional heat treatment.
H: Work-hardened temper
1: Simple work hardening only
4: Half-hard state (approximately halfway between fully annealed and fully hard)
A1050 H14 aluminum plate offers a balanced combination of moderate strength and good formability. It is commonly used in applications requiring bending, rolling, or light stamping.
What Does H24 Mean in A1050 H24 Aluminum Plate?
The H24 temper indicates a material that has been strain-hardened and then partially annealed. This controlled process improves formability while maintaining stable mechanical properties.
H: Work-hardened temper
2: Strain-hardened and partially annealed
4: Half-hard final condition
Compared with H14, A1050 H24 aluminum plate typically offers slightly better ductility and stress uniformity, making it suitable for deeper forming operations.
Aluminum A1050 H24 vs H14 Aluminum Plate: Temper Difference
| Item | A1050 H14 Aluminum Plate | A1050 H24 Aluminum Plate |
|---|---|---|
| Processing method | Cold worked only | Cold worked + partial annealing |
| Hardness level | Half-hard | Half-hard (more stable) |
| Formability | Good | Better |
| Internal stress | Higher | Lower |
| Typical use | Simple forming | Complex or deep 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 |
Values may vary depending on thickness and production standards.
