1050 aluminum sheet is a pure aluminum product, known for high conductivity, strong corrosion resistance, and easy forming.
It is one of the purest commercial aluminum grades on the market, often chosen when strength is not the top priority but purity and workability are.
What Is 1050 Aluminum Sheet
1050 aluminum sheet belongs to the 1000 series, the purest group in the aluminum family. It contains at least 99.5% aluminum, with only small amounts of iron and silicon.
This purity gives the sheet strong resistance to corrosion and good electrical conductivity.
Because it lacks major alloying elements, 1050 sheet is soft and easy to bend. It is not the strongest aluminum grade, but it excels where flexibility, purity, and finish quality matter more than raw strength.
Core Traits of 1050 Aluminum
Low mechanical strength compared to alloyed grades
Very high corrosion resistance
Good electrical and thermal conductivity
Easy to bend, stamp, and deep-draw
Bright, clean surface after polishing
Chemical Composition
Composition is what separates 1050 from other 1000-series grades like 1060 or 1100.
| Element | Min % | Max % |
|---|---|---|
| Aluminum (Al) | 99.5 | — |
| Iron (Fe) | — | 0.40 |
| Silicon (Si) | — | 0.25 |
| Copper (Cu) | — | 0.05 |
| Zinc (Zn) | — | 0.05 |
| Manganese (Mn) | — | 0.05 |
This high aluminum content is why 1050 sheet is a common choice for applications needing purity, such as chemical tanks or reflective panels.
Temper Options
Temper controls hardness and flexibility. 1050 sheet ships in several tempers, each suited to a different job.
| Temper | Hardness Level | Best For |
|---|---|---|
| O (annealed) | Softest | Deep drawing, spinning, tight bends |
| H12 | Light hard | General fabrication |
| H14 | Medium hard | Standard sheet stock |
| H16 | Firmer | Parts needing more stiffness |
| H18 | Hardest | Flat panels, minimal further forming |
Quick Temper Guide
H18 temper holds its shape but resists further bending
O temper bends the most without cracking
H14 temper is the most common stock temper
Thickness and Size Reference
1050 sheet comes in a wide thickness range, from thin foil-like sheet to thicker plate stock.

What Makes 1050 Aluminum Sheet Different?
1050 aluminum sheet is a commercially pure aluminum product. It is known for its high aluminum content, good formability, and good corrosion resistance.
It is not designed to be the strongest aluminum alloy. Instead, it is useful when a project needs a material that is:
Lightweight → Easy to Form → Easy to Process → Corrosion Resistant → Cost Effective
This balance makes 1050 aluminum sheet a practical option for many general manufacturing and fabrication projects.
1050 Aluminum Content and Material Characteristics
The aluminum content of 1050 is normally very high, with aluminum accounting for about 99.5% or more depending on the applicable standard and specification.
| Property | 1050 Aluminum |
|---|---|
| Aluminum content | About 99.5%+ |
| Density | About 2.70 g/cm³ |
| Formability | Excellent |
| Corrosion resistance | Good |
| Electrical conductivity | High |
| Thermal conductivity | High |
| Machinability | Moderate |
| Weldability | Good |
The exact mechanical and electrical values depend on the temper, thickness, and applicable standard.
1050 O vs H12 vs H14 vs H18

When high purity is important, 1050 can be a suitable choice.
When slightly higher strength is preferred while retaining good formability, 1100 can be considered.
1050 vs 3003 Aluminum Sheet
This is a more noticeable comparison.
| Feature | 1050 | 3003 |
|---|---|---|
| Strength | Lower | Higher |
| Formability | Excellent | Very good |
| Corrosion resistance | Good | Good |
| Weight | Similar | Similar |
| Machining | Moderate | Moderate |
