As a representative of Al-Mg alloys, 5052 H32 aluminum sheet shows unique material advantages in the field of automotive manufacturing. The combination of its magnesium content (2.2-2.8%) and chromium content (0.15-0.35%) gives the material excellent corrosion resistance, which can effectively resist the erosion of road salt spray, rain and automotive chemicals, and is particularly suitable for exposed parts of automobiles. After H32 state treatment (work hardening + stabilization), the tensile strength of 5052 H32 aluminum sheet reaches 210-260MPa, the yield strength is about 130MPa, and the elongation is 5%-12%, which perfectly balances the needs of strength and Formabilitas .
