Understanding 1050A O Aluminum Sheet
1050A O aluminum sheet belongs to the 1xxx series of aluminum alloys, which are known for their high aluminum purity. With a minimum aluminum content of 99.5%, this alloy is classified as commercially pure aluminum. The O temper indicates a fully annealed condition, giving the sheet its softest state, maximum ductility, and excellent cold-forming capability.
Because of its softness and purity, the 1050A O aluminum sheet is widely used in applications where strength is not critical, but corrosion resistance, electrical conductivity, and ease of fabrication are essential.
Chemical Composition of 1050A O Aluminum Sheet
Standard: EN 573-3
| Element | Content (%) |
|---|---|
| Aluminum (Al) | ≥ 99.50 |
| Silicon (Si) | ≤ 0.25 |
| Iron (Fe) | ≤ 0.40 |
| Copper (Cu) | ≤ 0.05 |
| Manganese (Mn) | ≤ 0.05 |
| Magnesium (Mg) | ≤ 0.05 |
| Zinc (Zn) | ≤ 0.05 |
| Titanium (Ti) | ≤ 0.03 |
The extremely high aluminum content gives the 1050A O aluminum sheet its excellent corrosion resistance, conductivity, and non-toxic characteristics.
