What is 5052 aluminum circle
5052 aluminum circle is aluminum-magnesium alloy round blanks with rust resistance. Benefiting from magnesium, it possesses moderate strength, excellent resistance to salt spray and marine corrosion, balanced thermal conductivity, superior weldability and good anodizing performance. 5052-O temper has excellent plasticity, allowing for smooth deep drawing, stretching, and bending without cracking; 5052-H temper offers even better strength and fatigue resistance.
It is mainly used for stretching and forming kitchenware and cookware, marine parts, automotive fuel tanks and sealed containers, outdoor traffic signs and markings, lighting fixtures, chemical storage components under normal pressure, and various corrosion-resistant metal stamping parts.

Why choose us
Multiple alloy options
Aluminum circles are available in commonly used alloys such as 1050, 1060, 1070, 1100, 3003, and 5052, allowing customers to select suitable material for cookware, lighting, spinning, stamping, or deep drawing.
Good forming performance
Suitable tempers can support manufacturing processes such as deep drawing, spinning, stamping, bending, and pressing, helping reduce cracking or edge defects during fabrication.
Wide size and thickness range
Buyers can source circles in different diameters and gauges for products ranging from small lamp parts and caps to large cookware and industrial components.
Surface quality
A clean, smooth surface and controlled edge quality are important for anodizing, polishing, coating, printing, and finished consumer products such as cookware and lampshades.
Custom processing options
Depending on the order requirements, customers may request specifications such as customized diameter, thickness, alloy, temper, surface finish, and packaging.
Efficient material utilization
Pre-cut aluminum circles can reduce customers’ own blanking work, lower scrap rates, and improve production efficiency compared with cutting discs from sheet or coil in-house.
Export-oriented packaging and supply support
For international buyers, secure packaging, clear product identification, and documentation support are important factors when selecting an aluminum-circle supplier.
Packaging&Shipping
They are usually packed with paper or plastic interleaving, moisture-proof wrapping,fumigated wooden pallets or non-wood packaging and reinforced outer packaging.
FAQs
1. What are the main advantages of 5052 aluminum circles?
5052 aluminum circles offer:
Good corrosion resistance
Higher strength than 1050, 1060, and 1100 aluminum
Good formability and weldability
Good fatigue resistance
Suitability for humid, outdoor, marine, and industrial environments
2. Is 5052 aluminum circle suitable for deep drawing?
Yes, especially in the O temper. 5052-O aluminum circles have better ductility and are commonly used for deep drawing, spinning, and forming applications. For less severe forming operations, H32 or H34 tempers may be used.
3. Is 5052 aluminum circle food-grade?
5052 aluminum can be used in food-contact-related applications when the material, surface treatment, manufacturing process, and applicable local food-contact regulations meet the required standards. Buyers should confirm relevant compliance requirements for their target market.
4. Is 5052 suitable for cookware?
Yes, 5052 can be used for certain cookware and kitchen components because of its corrosion resistance and strength. However, pure aluminum grades such as 1050 or 1060, and alloy 3003, are also widely used for cookware because of their forming properties and thermal conductivity. The best alloy depends on the cookware design and manufacturing process.
5. Can 5052 aluminum circles be customized?
Yes. Common customization options include:
Diameter
Thickness
Alloy and temper
Surface finish
Protective film
