Properties of 1050 Aluminum Sheet/Coil
1050 aluminum sheet belongs to commercially pure wrought family with a purity of 99.5% Aluminum. Except Al, 0.4% of Fe is added to 1050 aluminum sheet/coil, thus, it has high electrical conductivity. 1000 series aluminum group offers the best correction resistance compared to any alloy group, so does the 1050 aluminum sheet/coil. Zhongxin can manufacture and supply high quality 1050 aluminum sheet/coil with 18 years experience. Besides, different tempers are available, such as O (annealed), H12, H14, H18, etc.

1050 Aluminum Sheet/Coil
1050 aluminum sheet/coil is a commercially pure wrought aluminum alloy with a minimum aluminum content of 99.5%. As a member of the 1000 series aluminum family, 1050 aluminum (also written as 1050A aluminum) offers excellent corrosion resistance, high electrical conductivity, and good formability, making it one of the most widely used pure aluminum grades in industrial and decorative applications.
1050 Aluminum Alloy Composition
The 1050 aluminum alloy composition is mainly aluminum with small amounts of iron and silicon. Below is the typical 1050 aluminum chemical composition:
| Element | Si | Fe | Cu | Mn | Mg | Zn | Ti | Al |
|---|
| Content (%) | 0.25 | 0.40 | 0.05 | 0.05 | 0.05 | 0.07 | 0.05 | Remainder |
Because of this high purity, 1050 aluminum has fewer alloying elements than series like 3003 or 6061, giving it superior conductivity and corrosion resistance, but lower mechanical strength.
1050 Aluminum Mechanical Properties
The 1050 aluminum properties vary depending on temper. Common tempers include 1050 O aluminum (fully annealed, softest), 1050 H14 aluminum, 1050 H18 aluminum, and 1050 H24 aluminum (strain-hardened to different degrees). As temper increases from O to H18, tensile strength rises from around 65-95 MPa to over 135 MPa, while elongation decreases. This makes the 1050 series aluminum flexible enough to cover both deep-drawing applications (soft temper) and structural uses requiring more strength (hard temper).
1050 Aluminum Machinability
1050 aluminum machinability is rated as fair to good. Due to its high purity and softness, it tends to be gummy when cut at high speed, so sharp tooling and proper lubrication are recommended. It is more suitable for cold forming, spinning, and deep drawing than for high-speed CNC machining compared to alloys like 6061.
1050 Aluminum Sheet vs 1050 Aluminum Plate vs 1050 Aluminum Extrusion
We supply 1050 aluminum in multiple forms to meet different project needs:
- 1050 aluminum sheet — thickness typically 0.2mm-6mm, used for spinning, signage, and lighting reflectors
- 1050 aluminum plate — thicker gauge for chemical equipment and tooling
- 1050 aluminum extrusion — profiles used where complex cross-sections and high conductivity are required
1050 Aluminum vs Other Grades
Customers often ask how 1050 compares to other common grades:
- 1050 vs 1060 aluminum: 1060 has slightly higher purity (99.6% min) and even better conductivity, but 1050 offers a better balance of cost and performance for most general applications.
- 1050 vs 1100 aluminum: 1100 contains added copper for improved strength, while 1050 stays purer for better corrosion resistance and conductivity.
- 1050 vs 6061 aluminum: 6061 is a heat-treatable alloy with much higher strength, ideal for structural use, while 1050 is preferred for forming, conductivity, and corrosion resistance applications.
Applications
Thanks to its purity and corrosion resistance, 1050 aluminum is widely used in:
- Chemical processing equipment and tanks
- Electrical and conductive components (bus bars, cable sheathing)
- Lighting reflectors and decorative trim
- Food and pharmaceutical packaging components
- ACP (aluminum composite panel) cores
- Heat exchangers and radiators
