Introduction

5052 aluminum circle is a round disc cut from 5052 aluminum sheet —    a magnesium-alloyed aluminum containing 2.2–2.8% magnesium. It is    also called 5052 aluminum disc or 5052 aluminum round blank.


Compared to 1100 and 3003 aluminum circle, 5052 offers significantly    higher strength — tensile strength up to 260 MPa in H32 temper —    while maintaining good formability. It delivers the best corrosion    resistance of any common aluminum circle alloy, especially in marine,    saltwater, and chemical environments. It does not crack under forming    and accepts anodizing exceptionally well.


5052 aluminum circle is the preferred choice when strength and    corrosion resistance matter more than maximum formability. It is    widely used for pressure vessels, marine equipment, traffic signs,    chemical processing discs, and structural stamped components.

Key Properties at a Glance:

  • Density: 2.68 g/cm³ — lightweight

  • Yield strength (H32 temper): 195 MPa minimum
  • Elongation (O temper): 15–25% — good formability
  • Corrosion resistance: excellent — best among common circle alloys,    including marine environments
  • Thermal conductivity: 138 W/m·K
  • Food contact compliant: meets FDA and EU food safety regulations
  • Surface: accepts anodizing exceptionally well — widely used for    decorative anodized discs


Chemical Composition of 5052 Aluminum Circle:

ElementContent
Aluminum (Al)Balance (~96.7–97.7%)
Magnesium (Mg)2.2–2.8%
Chromium (Cr)0.15–0.35%
Silicon (Si)0.25% maximum
Iron (Fe)0.40% maximum
Copper (Cu)0.10% maximum
Manganese (Mn)0.10% maximum
Zinc (Zn)0.10% maximum
Other elements0.15% total maximum

The magnesium addition (2.2–2.8%) is what defines 5052. Magnesium    provides strong solid-solution hardening — significantly increasing    tensile and yield strength compared to 1100 and 3003. The chromium    addition (0.15–0.35%) further improves corrosion resistance and    controls grain structure. 5052 contains no copper, which makes it    more corrosion-resistant than alloys with copper additions.

For forming and deep-drawing applications, O (annealed)    temper is recommended. For structural, marine, and pressure    vessel applications, H32 or H34 is the standard    specification.

  • Choose 5052 when: higher strength is required,        the part will be exposed to marine or chemical environments,        anodized finish quality is critical, or the application involves        pressure vessels and structural components.

  • Choose        3003 when:        standard cookware production, general fabrication, or        cost-competitive deep-drawn parts are required.

  • Choose        1100 when:        maximum formability and highest thermal conductivity are the        primary requirements.


5052 Aluminum Circle Price


5052 aluminum circle price is higher than 1100 and 3003 because    magnesium is more expensive than manganese as an alloying addition,    and 5052 requires tighter process control during rolling and annealing.    The price premium is typically 10–20% above 3003 for equivalent    dimensions.

Price depends on four main factors:

  • Temper: O temper is the most competitively priced.    H32 and H34 carry a small premium for the additional processing.
  • Thickness and diameter: thicker and larger discs    cost more per piece but less per kg at scale.
  • Surface finish: mill finish is base price.    Anodized finish carries a premium — but 5052 anodizes better than    any other common circle alloy.
  • Order quantity: orders above 5 metric tonnes    receive better pricing. MOQ for custom sizes: 1–3 metric tonnes.

Applications of 5052 Aluminum Circle

5052    aluminum circles    are used where strength and corrosion resistance are the primary    requirements. The main applications are:


Pressure Vessels and Industrial Tanks

The strongest common circle alloy for non-heat-treatable applications.    5052-H32 aluminum circle is used as end caps, body blanks, and    closure discs for pressure cookers, LPG storage vessels, chemical    storage tanks, and hydraulic system components. The combination of    high strength, good formability, and excellent corrosion resistance    makes 5052 the preferred specification for pressure-rated components.


Marine and Offshore Components

5052 aluminum has the best saltwater corrosion resistance of any    common circle alloy. It is used for marine equipment discs, boat    fittings, offshore instrument housings, and coastal infrastructure    components. Where parts will be exposed to seawater, salt spray,    or humid marine environments, 5052 is the standard specification.


Traffic Signs and Road Signage

Round traffic signs, regulatory signs, and directional sign blanks.    5052-H34 provides the rigidity and strength required for large-format    sign panels that must withstand wind loading. The alloy's corrosion    resistance ensures long outdoor service life. Reflective sheeting    and paint adhere well to 5052 mill finish surfaces.


Anodized Decorative and Architectural Discs

5052 anodizes better than 1100 or 3003 — producing a clearer,    more uniform anodized layer with better color consistency. It is    used for decorative architectural panels, anodized sign blanks,    medals, trophy plates, and premium promotional discs where a    high-quality anodized surface finish is required.


Chemical Processing Components

Discs and blanks for chemical processing equipment, filtration    housings, and industrial vessel end caps. 5052's resistance to    a wide range of chemicals — including dilute acids, alkaline    solutions, and many industrial solvents — makes it reliable for    chemical processing environments where 3003 may not provide    sufficient corrosion protection.


Cookware and Food Equipment (Premium Grade)

5052 aluminum circle meets FDA and EU food contact regulations.    It is used for premium cookware where thinner walls with higher    strength are required — reducing weight while maintaining structural    integrity. It is also used for food processing equipment discs,    commercial kitchen components, and high-end cookware lines where    anodized finish quality is important.
