5052 H34 Aluminum Sheet

5052 H34 aluminum sheet is a medium-strength aluminum-magnesium alloy material. 5052-H34 is a strain-hardened aluminum alloy, known for its balanced strength, formability, and corrosion resistance.

5052 H34 aluminum sheet is a high-strength, corrosion-resistant material primarily composed of aluminum and magnesium, with small amounts of chromium. It is a non-heat-treatable alloy that can be strengthened through cold working processes. The H34 condition indicates that the material has been strain-hardened to medium strength, balancing formability and strength.

Haomei Aluminum, as a professional 5052-H34 aluminum sheet manufacturer, offers high-quality products that comply with AMS 4017 and ASTM B209 standards, designed specifically for the marine, automotive, and aerospace industries. Through optimized hot rolling (final rolling temperature of 320-350℃) and cold rolling processes (processing rate of 40-60%), we ensure materials with both high strength and salt spray corrosion resistance. Thicknesses from 0.15mm to 600mm are available, and we support bulk stock supply.

5052 H34 Aluminum Sheet Corrosion Resistance

5052-H34 performs excellently in marine environments due to its chromium content and protective oxide layer. It is resistant to seawater corrosion and can be anodized for enhanced protection.

5052 H34 Aluminum Sheet Applications

Due to its excellent corrosion resistance (especially in marine environments) and good weldability, 5052 H34 aluminum sheet is commonly used in:

Marine applications (e.g., hulls, fuel tanks)
Automotive parts
Building structures
Fuel tanks and pipelines
Heat exchangers
General sheet metal processing

5052 H34 Aluminum Sheet Processing Characteristics

Good cold working performance, suitable for processes such as bending and stretching.

Corrosion resistance is further enhanced after anodizing treatment on the surface.

Formability: Medium; suitable for bending and stamping, but less ductile than the H32 condition.
Machinability: At 0-100 aluminum alloy grade, machinability is at 50%.
Weldability: Compatible with TIG, MIG, and resistance welding.
Heat treatment: Not heat treatable; strength is achieved through strain hardening.

5052 H34 Aluminum Sheet Quality Requirements

Surface quality

Cracks and corrosion spots are not allowed; minor peeling or bubbles are acceptable (defect total area ≤5%, maximum depth ≤0.5mm).

Weldability

It is recommended to use ER5356 welding rods, and the mechanical properties remain stable after welding.

5052 H34 Aluminum Sheet Comparison with Other Conditions

H32 vs H34: H34 undergoes a higher degree of work hardening, resulting in higher tensile strength than H32.
H34 vs H112: H112 is a thermally processed condition, with strength lower than H34.

Comparison Between 5052 H34 Aluminum and 5052 H32

Although both H32 and H34 undergo strain hardening, H34 aluminum sheet has a higher degree of strain hardening, which increases strength and resistance to deformation. However, this also results in slightly lower formability compared to H32, as H32 is easier to form and bend. Therefore, H34 is suitable for applications requiring higher strength and resistance to deformation, while H32 is preferred when excellent formability is needed.

Strength: H34 has higher tensile and yield strength.
Formability: H32 has higher elongation (12-18% vs. 8-12% for H34).
Application: H34 is suitable for high-stress environments (e.g., marine applications), while H32 is more suited for form-intensive tasks.

5052-H34 aluminum sheet combines high strength, excellent corrosion resistance, and moderate formability, making it an ideal choice for demanding environments such as aerospace and marine engineering.
