1050 Aluminum Disc Circle

What is a 1050 Aluminum Disc and Circle?

1050 aluminum discs and circles are round plates made from 1050 aluminum alloy (commercially pure aluminum), known for their high purity, excellent processing performance, and wide range of applications.

1050 Aluminum Circle has a purity of up to 99.5%, offering excellent deep drawing performance, good formability, and stable overall properties. It is an ideal choice for cookware, lighting, and electrical applications. When selecting materials, the appropriate temper (such as H12/H24) should be chosen based on the application scenario (electrical conductivity/corrosion resistance/formability). For applications requiring high electrical conductivity, 1060 aluminum alloy should be given priority.

Each finish enhances key properties such as corrosion resistance, surface appearance, durability, and weather performance, making it ideal for cookware, lighting, signage, and electrical applications.

Mill Finish 1050 Aluminum Disc / Circle

Mill finish is the natural surface condition of 1050 aluminum discs and circles without any additional processing. It provides a smooth and uniform appearance with excellent formability, making it highly suitable for deep drawing cookware, stamping parts, and general industrial use where surface decoration is not required.

Polished 1050 Aluminum Disc / Circle

Polished aluminum discs feature a bright and mirror-like surface achieved through mechanical or chemical polishing processes. This type of 1050 aluminum circle is widely used in decorative lighting, kitchen utensils, reflectors, and other applications where high surface brightness and aesthetic appeal are essential.

Anodized 1050 Aluminum Disc / Circle

Anodized 1050 aluminum discs undergo an electrochemical oxidation process that forms a dense protective oxide layer on the surface. This treatment significantly improves corrosion resistance, wear resistance, and surface hardness, making anodized aluminum circles ideal for architectural panels, traffic signage, and outdoor environments.

Coated 1050 Aluminum Disc / Circle (PE / PVDF)

Coated aluminum discs are finished with PE or PVDF coatings to enhance weather resistance, UV stability, and color durability. These coated 1050 aluminum circles are commonly used in traffic signs, building decoration, appliance panels, and other applications requiring long-term performance in harsh environments.

When selecting the surface treatment process for 1050 aluminum circles or discs, factors such as the application environment, aesthetic requirements, and durability should be considered. We provide customized surface treatment solutions to meet specific project requirements and standards.

1050 Aluminum Disc Circle CC/DC

1050 aluminum circles are usually supplied in either “CC” (Continuous Casting) or “DC” (Direct Chill Casting) form. The choice between CC and DC is crucial, as they differ significantly in physical properties and price.

Comparison of CC vs. DC 1050 Aluminum Circles

Performance Index	1050 CC	1050 DC	Impact
Deep Drawing Performance	Relatively poor, not suitable for deep drawing	Excellent, suitable for complex deep drawing	DC can be used for deep-drawn cookware, while CC is mostly used for standard cookware
Surface Quality	Average	Good, no color difference after anodizing	DC is suitable for products requiring high surface quality
Elongation	Lower	Higher, better plasticity	DC has stronger fracture resistance and a wider processing range
Mechanical Strength	Relatively lower	Higher and more stable performance	DC products have a longer service life and are less prone to deformation
Anodizing Effect	Average	Excellent, with a uniform oxide film	DC is suitable for anodizing and other surface treatment processes

1050 Aluminum Circle CC / DC Price and Application Scenarios

Price: 1050 CC aluminum circles are usually cheaper than 1050 DC aluminum circles, as the production process is simpler and the cost is lower.

Application Scenarios:

1050 CC: Suitable for standard cookware (such as shallow-drawn pots and baking trays), decorative parts, and simple stamped components where deep drawing performance and surface quality requirements are not high.
1050 DC: Suitable for deep-drawn cookware (such as pressure cookers and deep pots), spun parts, high-quality anodized products, and components requiring higher strength and durability.

1050 Aluminum Circle CC / DC: Which One Should You Choose?

If deep drawing, spinning, or high-quality surface treatment is required: prioritize 1050 DC aluminum circles.
If the budget is limited and processing performance requirements are not high: 1050 CC aluminum circles are a more cost-effective choice.

Both types are based on 1050 aluminum alloy (aluminum content ≥99.5%), featuring good corrosion resistance, electrical conductivity, thermal conductivity, and workability. The main supply temper is O temper (soft), which is convenient for subsequent processing.

If cost is your primary concern, such as for making flat lids, shallow trays, or basic lighting reflectors, choose CC.
If you produce high-quality cookware, kettles, or any products requiring “deep drawing” (depth greater than 10–15 cm) or a premium polished/anodized appearance, choose DC.

1050 Aluminum Disc Circle CC/DC Diameter Tolerance

"CC/DC diameter tolerance" refers to the allowable deviation between the actual diameter and the nominal diameter of the disc:

CC (Continuous Casting)

Diameter tolerance of aluminum discs produced by continuous casting is generally controlled within ±0.5mm to ±1.0mm

DC (Hot Rolling)

Diameter tolerance of aluminum discs produced by hot rolling is relatively larger, generally within ±1.0mm to ±2.0mm
