What is 1050 Aluminum Coil?
1050 aluminum is classified as a commercially pure aluminum alloy, with a minimum 99.5% aluminum content. This high purity level is the source of its most defining characteristics. The coil form means it is supplied as a continuous, wound strip of metal, which is ideal for high-volume manufacturing processes like stamping, rolling, and forming.
Its composition makes it part of the 1xxx series of aluminum alloys, which are known for their excellent corrosion resistance, high electrical and thermal conductivity, and low mechanical strength.
The Technical datas of aluminum coil 1050:
Aluminum Association Designation: 1050
Old ISO Designation: Al 99.5
Common Tempers: O (Annealed), H12, H14, H16, H18, H19, H22, H24, H26
1. Chemical Composition (Weight % - ASTM B491)
The high purity of 1050 aluminum is the source of its key properties.
| Element | Min (%) | Max (%) |
|---|
| Aluminum (Al) | 99.50 | Balance |
| Silicon (Si) | - | 0.25 |
| Iron (Fe) | - | 0.40 |
| Copper (Cu) | - | 0.05 |
| Manganese (Mn) | - | 0.05 |
| Zinc (Zn) | - | 0.07 |
| Titanium (Ti) | - | 0.05 |
| Vanadium (V) | - | 0.05 |
| Other (Each) | - | 0.03 |
| Other (Total) | - | 0.10 |
2. Mechanical Properties
Mechanical properties vary significantly with temper. The following data are typical values based on standards like ASTM B209.
Typical Mechanical Properties at Room Temperature:
| Temper | Tensile Strength (MPa) | Yield Strength (0.2% Offset) (MPa) | Elongation (% in 50mm) | Hardness (Brinell) |
|---|
| O (Annealed) | 60 - 85 | 20 - 35 | 35% - 45% | 18 - 23 HB |
| H14 | 100 - 125 | 85 - 105 | 8% - 14% | 32 - 38 HB |
| H16 | 115 - 140 | 105 - 125 | 6% - 10% | 38 - 44 HB |
| H18 | 130 - 155 | 125 - 145 | 4% - 7% | 44 - 50 HB |
| H19 | 150 - 175 | 145 - 165 | 2% - 4% | ~52 HB |
Note: MPa (Megapascals). 1 MPa ≈ 0.145 ksi.
