1000 Series Aluminum Alloys: 1050 Aluminum Coil and 1100 Aluminum Coil
If you are sourcing high-purity aluminum materials with excellent forming performance, 1050 aluminum coil and 1100 aluminum coil from GNEE are reliable options widely used across multiple industries. Understanding their composition, properties, and applications will help you select the most suitable aluminum coil for your production needs.
1050 Aluminum Coil – Composition and Processing Characteristics
1050 aluminum coil belongs to the 1000 series pure aluminum family, with an aluminum content exceeding 99.5%. It is produced by introducing a very small amount of copper into pure aluminum, which enhances its overall processing performance while maintaining high purity.
Key Properties of 1050 Aluminum Coil
Excellent formability and workability
Strong corrosion resistance
Good weldability
High electrical and thermal conductivity
In most cases, 1050 aluminum coil is supplied in thicknesses ranging from 0.5 mm to 10 mm. Ultra-thick 1050 aluminum plate is rarely used due to limited demand. The material is primarily applied in sheet metal fabrication rather than heavy structural applications.
Because of relatively low market consumption, 1050 aluminum coil is often produced through custom orders, typically requiring around 10 days for manufacturing. For customers seeking faster delivery, 1060 aluminum coil is often considered as an alternative.
1100 Aluminum Coil – Material Features and Strength Levels
1100 aluminum coil is also a high-purity aluminum product, consisting mainly of aluminum with trace amounts of other elements. The difference in aluminum content between 1050 and 1100 aluminum coil is minimal, approximately 0.01%, and both materials show very similar processing behavior.
Mechanical Properties of 1100 Aluminum Coil
| Property | Typical Value |
|---|---|
| Yield Strength | ~80 MPa |
| Tensile Strength | ~110 MPa |
| Aluminum Content | ≥ 99.0% |
Due to its relatively low strength, 1100 aluminum coil is mainly used in applications where high mechanical strength is not required.
1100 Aluminum Coil Temper Options and Formability
1100 aluminum coil is commonly supplied in the O temper, meaning it is delivered in an annealed condition without heat treatment. This state offers excellent plasticity and machinability, making it ideal for forming and shaping operations.
In addition, 1100 aluminum coil can be cold-worked into tempers such as H12, H14, and H16, which provide increased hardness and strength while retaining good processing performance.
1100 Aluminum Coil – Key Performance Advantages
Main Features of 1100 Aluminum Coil
High ductility: Easily stretched, bent, and formed
Good electrical conductivity: Widely used in electrical and electronic fields
Excellent corrosion resistance: Suitable for acidic and alkaline environments
Outstanding machinability: Supports drilling, cutting, stamping, and other processes
These properties make 1100 aluminum coil a versatile material for both industrial and commercial applications.
Applications of 1050 Aluminum Coil and 1100 Aluminum Coil
Both 1050 aluminum coil and 1100 aluminum coil are widely used in industries that prioritize formability, corrosion resistance, and conductivity over high strength.
Typical Applications Include:
- Sheet metal fabrication parts
- Electrical and electronic components
- Chemical equipment and containers
- Roofing and decorative panels
- Heat dissipation systems
1100 Aluminum Coil for Heat Sink Applications
A common application of 1100 aluminum coil is in heat sink manufacturing. Heat sinks are designed to dissipate heat generated by electronic components. Aluminum is preferred due to its excellent thermal conductivity and cost efficiency.
When used as a heat sink material, 1100 aluminum coil offers:
- High thermal conductivity
- Lightweight structure
- Competitive cost compared to copper-based materials
During use, thermally conductive grease is typically applied between the electronic component and the aluminum heat sink to improve heat transfer efficiency.
