H32 H34 5052 Aluminum Sheet Medium to High Fatigue Strength Used in Seawater
Description of aluminum alloy 5052:
Alloy 5052 is a non-heat-treatable 2.5% magnesium alloy. Like other 5000-series high magnesium alloys 5052 has a high strength and is hardenable to a significant degree by cold working, enabling a series of “H” tempers, commonly H32 (1/4 Hard) and H34 (1/2 Hard) – as well as the soft annealed Temper O condition.
Features:
- Good weldability
- Medium to high fatigue strength
- Medium to high strength
- Very good corrosion resistance to seawater
