What Are Aluminum 1050 and Aluminum 1350?
Both 1050 aluminum and 1350 aluminum belong to the 1XXX series of pure aluminum alloys, characterized by high aluminum purity (≥99.5%), excellent corrosion resistance, and good formability.
While they share many similarities, the main differences lie in impurity limits-especially silicon content-and their targeted application fields, particularly electrical conductivity performance.
Aluminum 1050 vs 1350: Core Differences Overview
Although both alloys are classified as high-purity aluminum, 1350 aluminum is optimized for electrical conductivity, while 1050 aluminum is designed for general industrial applications.
Summary of Key Differences Between Aluminum 1050 and 1350
Electrical Conductivity: 1350 aluminum offers more stable and higher conductivity
Impurity Control: 1350 has stricter limits on silicon, iron, and trace elements
Application Focus: 1050 for general industrial use; 1350 for electrical conductors
Chemical Composition Comparison: Aluminum 1050 vs 1350
Both alloys have a minimum aluminum content of 99.5%, but allowable impurity levels differ.
Chemical Composition (Typical Limits)
| Element | Aluminum 1050 (%) | Aluminum 1350 (%) |
|---|---|---|
| Aluminum (Al) | ≥ 99.5 | ≥ 99.5 |
| Silicon (Si) | ≤ 0.25 | ≤ 0.10 |
| Iron (Fe) | ≤ 0.40 | ≤ 0.40 |
| Manganese (Mn) | ≤ 0.05 | ≤ 0.01 |
| Chromium (Cr) | - | ≤ 0.01 |
| Other (Each) | ≤ 0.03 | ≤ 0.03 |
Key takeaway:
Lower silicon and tighter impurity control in 1350 aluminum help minimize electrical resistance, making it more suitable for critical electrical applications.
Mechanical Properties: Aluminum 1050 vs 1350 (H14 Temper)
Mechanical Properties Comparison
| Property | Aluminum 1050 | Aluminum 1350-H14 |
|---|---|---|
| Tensile Strength | 76–140 MPa (varies by temper) | ~110 MPa |
| Yield Strength | 25–120 MPa (varies by temper) | ~96 MPa |
| Elongation at Break | 4.6%–37% | ~6.8% |
| Heat Treatable | No | No |
Notes:
1050 aluminum offers broader ductility options through different tempers (O, H12, H14, H18).
1350 aluminum focuses on consistent conductivity with moderate strength, typically supplied in H14 temper.
Electrical Conductivity: Aluminum 1050 vs 1350
Both alloys exhibit high electrical conductivity, approximately 61% IACS, but 1350 aluminum provides better consistency and reliability due to stricter impurity control.
1050 Aluminum: Suitable for general electrical and thermal conduction needs
1350 Aluminum: Preferred for conductors, transformer windings, busbars, and transmission lines

Selection Considerations: 1050 or 1350 Aluminum?
For general industrial fabrication and forming, choose 1050 aluminum
For high-conductivity electrical applications, choose 1350 aluminum
For copper-aluminum connections → Both alloys require proper galvanic corrosion protection
In industry trends, 1050 aluminum is often replaced by 1060 aluminum, while 1350 aluminum remains irreplaceable in the electrical sector.
