Mechanical Properties and Performance of Aluminium Alloy AA5052: A Comprehensive Analysis

This study investigates the mechanical properties and performance of Aluminium Alloy AA5052, a material commonly used in various engineering applications due to its excellent corrosion resistance, formability, and moderate strength. The investigation includes an analysis of key mechanical properties such as tensile strength, hardness, yield strength, modulus of elasticity, thermal conductivity, fatigue strength, impact toughness, and elongation at break. A total of 20 samples were tested for each mechanical property, with results revealing a general trend of increasing tensile strength, hardness, and fatigue strength with increasing percentages of magnesium (Mg) and chromium (Cr). The mechanical property data indicated that the tensile strength of AA5052 ranged from 220 MPa to 370 MPa, while hardness varied from 65 to 125 Vickers, yield strength ranged from 175 MPa to 310 MPa, and modulus of elasticity ranged from 69.5 GPa to 82.0 GPa. Fatigue strength varied from 110 MPa to 180 MPa, and impact toughness ranged from 22 J to 52 J. Magnesium content showed a positive correlation with tensile strength and elongation, whereas chromium influenced hardness and yield strength. Paired sample T-tests revealed statistically significant correlations between various mechanical properties, with tensile strength showing a strong correlation with hardness (r = 0.65), yield strength (r = 0.74), and impact toughness (r = 0.60). These results highlight the alloy's superior performance in structural applications where strength and durability are critical. The findings provide valuable insight into optimizing the alloy's composition for enhanced mechanical performance in industrial applications.
