Contact GNEE today for technical support and competitive pricing on 1050 aluminum plate and sheet.
Overview of 1050 Aluminum Sheet and Plate
1050 aluminum sheet plate belongs to the 1xxx series of industrial pure aluminum alloys. According to international aluminum designation rules, the last two digits, "50," indicate that the aluminum content must be no less than 99.5%, which is also clearly specified in GB/T 3880-2012.
Because 1050 aluminum does not contain significant alloying elements, its manufacturing process is relatively simple, resulting in lower production cost and wide market availability. It is one of the most commonly used aluminum sheet grades in conventional industries.
Key characteristics of 1050 aluminum plate include high plasticity, excellent corrosion resistance, good electrical and thermal conductivity, and relatively low mechanical strength. The alloy cannot be strengthened by heat treatment and relies on cold working to improve strength.

1050 H14 Aluminum Plate Features and Advantages
1050 H14 aluminum plate is one of the most widely used tempers and offers:
- Excellent formability and weldability
- High plasticity and thermal conductivity
- Low density (2.71 g/cm³)
- Suitable for gas welding, TIG welding, and spot welding
- Strong corrosion resistance
- Available as sheet, plate, strip, and coil
- Not heat-treatable
Applications of 1050 Aluminum Sheet and Plate
Due to its properties, 1050 aluminum sheet plate is commonly used in applications requiring high corrosion resistance and formability but moderate strength, including:
- Traffic and highway signs
- Architectural facade signage
- Kitchenware and cookware
- Lighting equipment and reflectors
- Decorative panels and nameplates
- Heat sinks and lamp housings
- Chemical containers and equipment
- Electrical appliances and stamped parts
1050 Aluminum Sheet Price Overview
Because 1050 aluminum contains almost no alloying elements and requires a simple production process, it is more affordable than many other aluminum alloys. Market prices typically range from USD 2.3 to 2.7 per kg, depending on thickness, temper, surface finish, and order volume.
How to Prevent Oxidation of 1050 Aluminum Plate
Although 1050 aluminum plate offers good corrosion resistance, improper storage can cause surface oxidation. GNEE recommends:
- Store in a dry, ventilated, non-corrosive environment
- Avoid rain, snow, and condensation exposure
- Control rolling oil moisture below 0.4%
- Use sealed packaging with desiccant
- Do not open sealed packages immediately when moving to humid areas
- Ensure packaging wood moisture ≤18% and temperature ≤45°C
1050 Aluminum Plate vs 1060 Aluminum Plate
Both alloys belong to the 1000 series aluminum plate:
1050 aluminum plate: ≥99.50% aluminum
1060 aluminum plate: ≥99.60% aluminum
1060 aluminum is slightly softer and more suitable for deep drawing, but the performance difference is minimal. Neither alloy can be strengthened by heat treatment.
1050 Aluminum Plate vs 5052 Aluminum Plate
| Feature | 1050 Aluminum Plate | 5052 Aluminum Plate |
|---|---|---|
| Aluminum Content | ≥99.5% | ~95% |
| Main Alloy Element | None | Magnesium (~4%) |
| Strength | Low | High |
| Corrosion Resistance | Good | Excellent (marine grade) |
| Typical Use | Decorative, electrical | Marine, tanks, pressure parts |
| Price | Lower | Higher (~USD 250/ton more) |
1050 H14 vs H24 Temper for 1050 Aluminum Plate
H14 aluminum plate: Work-hardened only
H24 aluminum plate: Work-hardened + partial annealing
Both have similar strength, but H24 aluminum plate offers higher elongation, making it more suitable for forming applications.
