Overview of 1050 Aluminum Coil Material
1050 aluminum coil contains more than 99.5% aluminum, making it a typical industrially pure aluminum alloy. It features high plasticity, excellent corrosion resistance, and good electrical and thermal conductivity, while its mechanical strength remains relatively low.
As part of the pure aluminum series, 1050 aluminum strip and coil have chemical composition and mechanical behavior similar to the 1060 series. In many applications, 1050 aluminum coil has been gradually replaced by 1060 aluminum products, though 1050 remains widely used due to its simple production process and competitive price.
According to international alloy designation principles and China's GB/T 3880-2006 standard, aluminum alloys with an aluminum content of 99.5% or higher qualify as 1050 aluminum.
Key Characteristics of 1050 Aluminum Coil
- Industrial pure aluminum with very high purity
- Low density and lightweight structure
- Excellent corrosion resistance
- Good electrical and thermal conductivity
- Outstanding plastic deformation performance
- Cannot be strengthened by heat treatment
- Accepts contact welding and gas welding

Processing Characteristics of 1050 Aluminum Coil
Industrially pure aluminum exhibits the general characteristics of aluminum, including good plastic processing capability. 1050 aluminum coil can be processed into plates, strips, foils, and extruded products, and supports:
Gas welding
Argon arc welding
Spot welding
Although 1050 aluminum coil cannot be strengthened through heat treatment, its strength can be improved through cold deformation. Annealing is the only heat treatment method used for this alloy.
Heat Treatment Specification for 1050 Aluminum Coil
| Heat Treatment Type | Process Description |
|---|---|
| Complete Annealing | 390–430°C, hold 30–120 min; furnace cool to below 300°C, then air cool |
| Rapid Annealing | 350–370°C, hold 30–120 min; air or water cool |
| Quenching & Aging | Quench at 500–510°C; artificial aging at 95–105°C for 3 h; natural aging 120 h |
The recrystallization temperature of 1050 aluminum coil is typically around 200℃, depending on impurity content and degree of deformation.
Cold Work Hardening Behavior of 1050 Aluminum Coil
Annealed sheet tensile strength: 80–100 MPa
Yield strength: 30–50 MPa
Elongation: 35%–40%
After 60%–80% cold deformation:
Tensile strength increases to 150–180 MPa
Elongation decreases significantly
Increasing iron and silicon content can improve strength but reduces plasticity, conductivity, and corrosion resistance. Proper control of annealing temperature and cold deformation is essential to achieve desired mechanical properties.
