AW 5754 H22 Aluminum: Corrosion-Resistant AlMg3 Alloy for Marine, Automotive & Industrial Applications | Mingtai Aluminum

Introduction: The Versatile Al-Mg Alloy for Demanding Environments

AW 5754 H22 aluminum—also known as AlMg3 or EN AW-5754—is a medium-strength, non-heat-treatable aluminum-magnesium alloy that has become an industry standard for applications requiring exceptional corrosion resistance, good weldability, and balanced mechanical properties. With a magnesium content of 2.6–3.6% , this 5xxx series alloy delivers superior performance in seawater, industrial atmospheres, and chemically aggressive environments.

The H22 temper indicates a work-hardened condition followed by partial annealing—often described as “quarter hard”—which provides a significant boost in yield strength while maintaining good ductility for forming operations. This makes 5754-H22 an ideal choice for structural applications that demand both strength and formability.

Mingtai Aluminum (Stock Code: 601677), with over 27 years of experience and an annual production capacity exceeding 1.45 million tonnes, supplies premium AW 5754 H22 aluminum sheet and plate certified to EN 573-3 and EN 485-2 standards. Our products are approved by CCS, ABS, LR, KR, and CE for worldwide project compliance.

Key Properties of AW 5754 H22 Aluminum

1. Exceptional Corrosion Resistance

5754 aluminum offers excellent resistance to seawater and industrially polluted atmospheres. Its ability to withstand saline environments without rapid degradation makes it a true marine-grade alloy. Upon exposure to oxygen, the magnesium in 5754 reinforces the natural aluminum oxide layer, creating a self-healing film that resists pitting and galvanic corrosion during continuous saltwater spray or full immersion. In ASTM B117 salt spray tests, 5754-H22 withstands 1,500+ hours without significant corrosion.

2. Balanced Mechanical Strength

As one of the highest-strength non-heat-treatable aluminum alloys, 5754-H22 delivers reliable mechanical performance:

3. Excellent Weldability

5754 aluminum offers excellent weldability across all standard methods—gas, arc, and resistance welding. MIG (GMAW) and TIG (GTAW) welding are the standard techniques for structural joints, with filler alloys such as 5356 or 5554 recommended to preserve corrosion resistance in the weld zone. Welded joints achieve 85%+ joint strength compared to the base metal. Because AlMg3 is not heat-treatable, welded joints do not suffer the drastic strength loss seen in 6000-series alloys.

4. Superior Formability

The H22 temper provides a balance of strength and ductility that enables cold stamping, deep drawing, and bending without cracking or deformation. The alloy exhibits very good cold workability, making it suitable for complex forming operations. For applications requiring maximum formability, 5754 is also available in O (annealed) or H111 tempers.

5. Decorative Anodizing Capability

5754 aluminum is classified as an anodizing quality alloy, making it suitable for decorative anodized finishes. This allows manufacturers to achieve both corrosion protection and aesthetic appeal in a single material.
