5052-H32 Sheet	Work-hardened, high formability, non-heat-treatable	Marine panels, appliance enclosures, signage	Superior corrosion resistance, easily formed; lower strength, not machinable
5052-H34 Plate	Higher work-hardening than H32, moderate strength/formability	Pressure vessels, transportation, tank fabrication	Improved durability, good for cold working; still not heat-treatable
6061-T6 Extrusion	Heat-treated, high strength, outstanding machinability	Structural frames, machinery, automotive parts	Excellent strength/machining, weldable; less formable, moderate corrosion
6061-T4 Plate	Heat-treated then naturally aged, increased ductility	Aerospace components, construction, fixtures	Balanced strength/ductility, weldable; not as strong as T6, higher cost
6061-O Annealed	Fully annealed, maximum ductility, low yield strength	Bending, deep drawing, customized shapes	Easily shaped, great for forming; weakest temper, limited load-bearing use

5052-H32 Sheet

5052-H32 is the most common type of 5052, delivered in a work-hardened (strain-hardened) and partially annealed state. Known for its superb formability and exceptional resistance to saltwater corrosion, this variation suits industries requiring complex bends or deep drawing. Buyers should prioritize 5052-H32 when sourcing for marine panels, chemical tanks, appliances, and signage—particularly where exposure to moisture or corrosive elements is high. The main trade-off is its lower strength and poor machinability, which may increase fabrication costs if complex machining is necessary.

5052-H34 Plate

5052-H34 offers slightly higher strength than H32, making it suitable for applications demanding increased durability without sacrificing too much formability. It is commonly used in the manufacture of pressure vessels, tankers, and transport components subjected to moderate loading and stringent corrosion requirements. B2B buyers benefit from its improved residual strength after cold work. However, as it is not heat-treatable, those requiring even higher strength for structural loads may need to consider alternatives. H34’s processing is widely available, but buyers should ensure supplier capability for correct temper certification.

6061-T6 Extrusion

6061-T6 is the most popular form of 6061, supplied after solution heat treating and artificial aging to yield maximum strength and excellent machinability. Its outstanding mechanical characteristics make it a mainstay for structural frames, automotive components, and precision-machined parts. This type is recommended for buyers seeking a versatile, high-strength material with reliable performance in welded or machined assemblies. The limitations are reduced formability compared to 5052 and slightly lower corrosion resistance—important for harsh or marine environments.

6061-T4 Plate

6061-T4 is heat-treated and then naturally aged, providing increased ductility alongside significant mechanical strength. This temper is often used for aerospace components, construction elements, and fixtures requiring further formability or post-forming processes before final strengthening. B2B purchasers should select 6061-T4 when secondary forming operations are needed before a final hardening cycle. The cost is generally higher, and while it’s still weldable, T4 does not match the full strength of T6 after fabrication.

6061-O Annealed

6061-O is a fully annealed state, delivering the highest ductility and most workable condition of all 6061 forms—ideal for deep drawing or forming of complex shapes. It is the preferred option for buyers who need custom bent, rolled, or shaped aluminum parts with minimal risk of cracking. The trade-off for this ease of fabrication is very low yield strength, restricting its use in load-bearing or structural applications. Buyers should match its use to non-critical load applications or plan for subsequent heat treatment if greater strength is required.
