5052-H32 Aluminum Sheets and Coils
5052-H32 aluminum sheets and coils belong to the aluminum-magnesium alloy family, one of the most widely used rust-resistant aluminum alloys today. The designation “5052” refers to the alloy type in the 5xxx series, which offers the highest strength among non-heat-treatable aluminum alloys. Compared with 1100 or 3003 alloys, 5052 has superior fatigue strength. The marine-grade 5052 aluminum plate also exhibits excellent resistance to marine atmosphere and seawater corrosion.
The “H32” temper means the material has been strain-hardened and then stabilized through a low-temperature treatment, ensuring balanced strength and formability. Thanks to its excellent corrosion resistance, moderate strength, and outstanding formability, 5052-H32 is widely used in aerospace, shipbuilding, transportation, construction, home appliances, and other sectors.
Key Properties of 5052-H32 Aluminum Alloy
1.Outstanding Corrosion Resistance
Exceptional resistance to marine and industrial atmospheric environments. Ideal for applications exposed to salt spray, humidity, and harsh conditions.
2.Moderate Strength with High Fatigue Resistance
Its tensile strength is about 210–260 MPa, and its yield strength is about 130–195 MPa. Its strength is better than that of 1xxx and 3xxx series aluminum alloys, and it is stable in load-bearing structures.
3.Excellent Weldability and Workability
Suitable for various welding techniques (e.g., TIG, MIG), with stable weld joint performance. Excels in cold forming processes like bending, stamping, and edge curling.
4.Superior Surface Finish Compatibility
High surface smoothness and excellent for anodizing. Supports decorative treatments such as powder coating, electrophoresis, and color coating.
