Title

The 1/8 inch thick (0.1250 inch) 5052 aluminum disc is a commonly used circular aluminum-magnesium alloy material that combines excellent corrosion resistance, moderate strength, and outstanding machinability. It plays a key role in industrial manufacturing, aerospace, electronic equipment, and consumer goods production.

What is a 5052 Aluminum Disc?

The 5052 aluminum disc is primarily an Al-Mg (aluminum-magnesium) alloy, with a magnesium content of approximately 2.2-2.8%. This gives it higher strength and hardness than 1000 and 3000 series aluminum while maintaining superior corrosion resistance.

5052 aluminum discs can undergo various surface treatments such as polishing or anodizing to enhance both aesthetics and functionality. In particular, anodizing further improves surface hardness and corrosion resistance, making it suitable for demanding applications.

Common temper states for 5052 aluminum discs include H32, H34, H36, and O (fully annealed).

O Temper (Annealed State):

Characteristics: Lowest strength, highest plasticity.

Applications: Ideal for extremely complex forming and multiple deep-drawing operations, such as cookware or precision spinning components.

H32 Temper (1/4 Hard):

Characteristics: Moderate strength, good plasticity.

Applications: Most common temper, balancing strength and formability, suitable for general bending, forming, and stretching.

H34 Temper (1/2 Hard):

Characteristics: High strength, lower plasticity.

Applications: Suitable for components requiring higher rigidity with minimal bending or forming.

5052 Aluminum Disc Technical Specifications

Product Features of 5052 Aluminum Circle

1. Corrosion Resistance
As an aluminum-magnesium alloy, 5052 naturally forms a protective oxide layer, effectively resisting corrosion in atmospheric and marine environments.

2. Excellent Machinability
5052 aluminum discs have high plasticity and corrosion resistance. While they cannot be strengthened through heat treatment, they maintain good formability in semi-cold work hardening. They are suitable for bending, stamping, deep drawing, and other forming processes.

3. Weldability
Whether using CNC machining, stamping, or TIG/MIG welding, 5052 aluminum discs allow high-precision operations, improving production efficiency and reducing manufacturing difficulty.

4. Lightweight
Compared with pure aluminum, 5052 offers higher strength while remaining lightweight, meeting engineering requirements for load-bearing and fatigue resistance.

5. Environmentally Friendly
Aluminum is 100% recyclable, making it a sustainable material choice.

Applications of 5052 Aluminum Discs

Marine and Outdoor Facilities
Thanks to excellent salt-spray resistance and oxidation protection, 5052 aluminum discs are widely used in ship components, outdoor lighting brackets, and protective panels. Even after long-term exposure to wind, rain, and high-humidity environments, the discs maintain structural integrity and surface smoothness, ensuring safety and aesthetic appeal.

Kitchenware
5052 aluminum is non-toxic and safe for direct food contact. It is commonly used in cookware such as non-stick pans, pressure cookers, and milk pots, offering durability and excellent formability for deep-drawing processes.

Transportation
In automotive manufacturing, 1/8″ thick 5052 aluminum discs are used for engine covers, bus luggage panels, anti-slip decorative plates, and fuel tanks. The combination of moderate strength and corrosion resistance makes it ideal for lightweight vehicle components while ensuring durability and reliability.

Pressure Vessels and Liquid Storage Systems
5052 aluminum discs are widely used for small oil tanks, storage tank end caps, and industrial containers. Their corrosion resistance and weldability ensure that tanks and caps maintain airtightness and structural stability under internal pressure and environmental stress, preventing leaks or deformation-crucial in food processing, chemical storage, and liquid transportation.

Why Choose HAOMEI Aluminum?

1. High-Precision Cutting
   Using CNC laser cutting or plasma cutting, the diameter and circularity of discs are strictly controlled within customer specifications.

2. Surface Treatment and Flatness
   High-quality aluminum discs are pre-flattened to avoid warping due to internal stress, particularly important for end-cap applications requiring airtightness.

3. Smooth Edges
   Edges of 1/8 inch thick discs are finished smoothly without burrs, reducing post-processing costs and extending the lifespan of stamping molds.
