5052 H34 aluminum sheet belongs to Al-Mg alloy, and its characteristics are as follows:
– Corrosion resistance: The magnesium content (2.2%-2.8%) gives it excellent corrosion resistance and is suitable for humid or corrosive environments.
– Weldability: Supports multiple welding processes such as MIG and TIG, and the welded joint has high strength, which is convenient for complex structure manufacturing.
– Cold workability: Good plasticity in the semi-cold hardening state, can be stamped and bent, and the strength is improved after cold hardening.
– Medium strength: Tensile strength is 173-244 MPa, which meets the needs of medium-load components.
