5052 Aluminum Circle
Product Overview
5052 Aluminum Circle is a non-heat-treatable Al-Mg alloy disc known for its excellent corrosion resistance, stable mechanical strength, and reliable forming performance.
It is widely used in applications where structural integrity, environmental durability, and controlled forming behavior are required, making it a preferred material for cookware, pressure components, industrial enclosures, transportation, and marine-related parts.
Compared with pure aluminum circles such as 1050 or 1060, 5052 aluminum circles offer significantly higher strength and service life, while maintaining good workability in stamping, deep drawing, and spinning processes.
Alloy Characteristics
Aluminum–Magnesium Alloy System
5052 aluminum alloy contains 2.2–2.8% magnesium (Mg) as the primary alloying element.
Strength is achieved through solid-solution strengthening rather than heat treatment, ensuring long-term performance stability.
- Non-heat-treatable alloy
- Strength enhanced by cold working
- Stable metallurgical structure for continuous production
Corrosion Resistance
5052 aluminum circles exhibit outstanding resistance to:
- Humid and coastal environments
- Salt spray exposure
- Food-contact conditions
- Mild chemical media
This makes the alloy particularly suitable for cookware, marine components, and outdoor industrial applications.
Formability and Processing Balance
The alloy provides a practical balance between strength and formability:
- Low risk of cracking during deep drawing
- Good resistance to orange peel effect
- Predictable springback behavior
- Consistent dimensional stability

Manufacturing Process
5052 aluminum circles are typically produced through a controlled process:
- High-quality 5052 hot-rolled or cold-rolled aluminum coil
- Precision annealing to optimize grain structure
- CNC blanking or high-speed punching
- Deburring and surface leveling
- Batch inspection for dimensions, hardness, and surface quality
This process ensures:
- Uniform grain distribution
- Stable deep-drawing performance
- Clean surfaces free from oil residue and edge defects
