Introduction to 1050 Aluminum Sheet and Aluminum Plate
Aluminum is one of the most widely used metals globally, valued for its low density, corrosion resistance, and excellent workability. Among aluminum alloys, the 1xxx series aluminum sheets and plates stand out due to their exceptionally high purity.
1050 aluminum sheet is a representative alloy in this series, offering outstanding corrosion resistance, electrical conductivity, and formability. These characteristics make it a preferred material for many non-structural and functional applications across electrical, chemical, and general manufacturing sectors.

What Is a 1050 Aluminum Sheet?
1050 aluminum sheet and aluminum plate belong to the 1xxx series of wrought aluminum alloys, which are defined by their high aluminum content. Specifically, 1050 aluminum contains at least 99.5% pure aluminum, placing it among the purest commercial aluminum grades available.
This high purity gives 1050 aluminum excellent resistance to corrosion and very good electrical and thermal conductivity. While its mechanical strength is relatively low compared with alloyed grades, its workability and surface quality make it ideal for many industrial and commercial uses.
Chemical Composition of 1050 Aluminum Sheet
| Element | Content (%) |
|---|---|
| Aluminum (Al) | ≥ 99.5 |
| Iron (Fe) | ≤ 0.19 |
| Silicon (Si) | ≤ 0.20 |
| Copper (Cu) | ≤ 0.05 |
| Manganese (Mn) | ≤ 0.05 |
| Magnesium (Mg) | ≤ 0.05 |
| Zinc (Zn) | ≤ 0.05 |
| Titanium (Ti) | ≤ 0.03 |
Small amounts of iron and silicon slightly improve mechanical stability while maintaining excellent formability.
