This flexibility makes 5052 Aluminum Circle widely applicable in various metal fabrication scenarios.
2.3 Corrosion Resistance: Adapt to Complex Working Environments
Many fabricated products work in harsh environments, so corrosion resistance is critical. 5052 Aluminum Circle excels here compared to other aluminum circles.
Magnesium and chromium in the alloy form a dense oxide film on the surface, protecting the internal aluminum matrix from external corrosion.
2.3.1 Key Performance of Corrosion Resistance
Its corrosion resistance adapts to various harsh fabrication environments in four aspects:
Atmospheric corrosion resistance: A dense oxide film resists atmospheric substances, avoiding rust and discoloration, suitable for outdoor fabricated products like street lamp brackets and outdoor decorative parts.
Seawater corrosion resistance: Superior to 3003 and 1050/1100 circles, magnesium forms stable compounds to resist chloride ion corrosion, suitable for marine fabricated products like marine hardware, ship sheet metal parts and offshore platform accessories.
Chemical corrosion resistance: It resists most neutral and weak acid-alkali media, suitable for chemical and food field products like chemical containers and food packaging parts.
Stress corrosion resistance: Chromium reduces crack sensitivity, preventing cracking during processing and use, ensuring product safety.
2.3.2 Corrosion Resistance Test Results
A 48-hour salt spray test shows no obvious pitting or rust on its surface, with a corrosion rate <0.01mm/a, meeting most fabrication requirements.
Compared with 3003 circles (prone to exfoliation corrosion after cold working), it has more stable corrosion resistance and wider applicability.
2.4 Formability: Adapt to Complex Cold Processing in Metal Fabrication
Metal fabrication involves complex cold processing, so formability is an important indicator for material selection.
5052 Aluminum Circle has excellent formability, adapting to various cold processing, with smooth, accurate and defect-free processed products.
2.4.1 Key Formability Performance
Its excellent formability meets complex fabrication needs in four aspects:

Deep drawing performance: O-state elongation ≥25% (higher than 3003 and 1050 circles), enabling one-time deep drawing of large-depth parts to improve efficiency.
Bending performance: It can be bent to various angles (even 180°) without cracking, suitable for brackets, frames and connecting parts.
Cutting performance: It is easy to cut (turning, milling, drilling) with smooth surfaces and high accuracy, reducing tool wear and costs compared with high-strength aluminum alloys.
2.4.2 Selection of Formability State
Formability is related to its state: O-state has the best formability for deep drawing and bending; H32/H34 states balance strength and formability.
H32 and H34 states have slightly reduced formability but better strength, suitable for scenarios needing both strength and formability.
Customers can select the appropriate state according to their specific metal fabrication processes and needs.
2.5 Weldability: Meet the Welding Requirements of Metal Fabrication
Welding is essential in many fabrication scenarios to assemble parts, so weldability is crucial for materials.
