Advantages of 5005 H34 Aluminum

Excellent corrosion resistance: Magnesium forms a dense oxide film on the surface, giving the alloy outstanding resistance to atmosphere, seawater, and industrial environments, especially suitable for outdoor and marine applications.
Good weldability: High-quality welding can be achieved without special processes, with minimal loss of weld strength, suitable for manufacturing structural components.
Balanced medium strength and workability: The H34 temper (strain-hardening + stabilization) provides 145–185 MPa tensile strength and 115–155 MPa yield strength, while retaining some ductility for forming processes such as bending and stamping.
Surface treatment compatibility: After anodizing, it can achieve a bright and uniform appearance. Its color tone matches well with alloy 6063, making it widely used in architectural decoration; however, for applications requiring exceptionally high surface appearance, “special anodizing quality” should be specified to avoid streaks.

5005 Aluminum Alloy

5005 belongs to the aluminum-magnesium alloy series and is a widely used corrosion-resistant aluminum. Its main characteristics include:

Main alloying element: Magnesium, typically 0.5%–1.1%. The addition of magnesium increases the strength of aluminum while maintaining good corrosion resistance.
Excellent corrosion resistance: Among all aluminum alloys, the 5xxx series (magnesium-based) has some of the best corrosion resistance, especially against marine and industrial atmospheric corrosion. It is also known as “marine-grade aluminum.”
Medium strength: Stronger than pure aluminum (such as 1100) and 3003 alloy, but lower than 5052.
Good formability: Capable of deep drawing, bending, and other forming processes.
Excellent anodizing effect: After surface treatment, it can obtain a beautiful and durable oxide film, suitable for decorative materials.
Good weldability: Suitable for various conventional welding methods.

Typical applications of 5005 aluminum alloy:

Construction: Ceilings, wall panels, louvers, decorative strips, rolling shutters.
Vehicle interiors: Interior panels of automobiles and trains.
Home appliance panels: Exterior panels for refrigerators, washing machines, etc.
Signs and nameplates.
Kitchenware.

H34 Temper

"H" stands for "strain-hardened." This indicates a method that increases the material’s strength through cold working (such as cold rolling or cold drawing).

The numbers following "H" have specific meanings:

The first digit (HX): Indicates the basic type of strain-hardening treatment.

H1X: Strength achieved solely through strain-hardening.
H2X: Strain-hardened and then partially annealed.
H3X: Strain-hardened and then stabilized by low-temperature heat treatment. This is particularly important for magnesium-containing 5xxx alloys to prevent “strain corrosion cracking” caused by natural aging during service while maintaining strength.

The second digit (HX4): Indicates the strength level of the material — the larger the number, the higher the strength.

HX4: Represents that the tensile strength is half the difference between the O temper (fully annealed) and the HX8 temper (full hard).

Therefore, the specific meaning of H34 is:

After work hardening, the material undergoes stabilization treatment to achieve a half-hard temper.

Compared with the fully annealed O temper, 5005 aluminum in the H34 temper has higher strength and better flatness.

5005 H34 is preferred when medium strength, high corrosion resistance, and excellent surface finishing are required, such as in building curtain walls, marine interiors, and electronic housings. If higher strength is needed (e.g., for mechanical components), 6061 T6 should be considered; if cost is a primary concern and corrosion resistance requirements are moderate, 3003 H24 is a suitable choice.

With its advantages in corrosion resistance, formability, and surface finishing, 5005 H34 aluminum alloy is widely used in architecture, transportation, and electronics. Its H34 temper balances strength and ductility, making it suitable for diverse manufacturing needs. When selecting materials, it is important to consider mechanical requirements, environmental conditions, and budget constraints of the specific application, and communicate sufficiently with suppliers to ensure that the material properties match the actual needs.
