Study of Aluminium–Magnesium Alloy by Powder Metallurgy

Aluminium–Magnesium (Al–Mg) alloys are widely used in light weight but high strength applications in various industries such as aerospace, automotive, etc. Also other improved properties are corrosion resistance and mechanical properties. This study explores the synthesis and characterization of Al–Mg alloys fabricated through the powder compositions, compaction under controlled pressure and sintering at optimized temperature to enhance densification and mechanical performance. The microstructural analysis, density measurement, hardness testing and conductivity are conducted to assess the influence of Mg content on the alloy properties. The results indicate that increasing Mg content enhances strength and microhardness due to solid solution strengthening and grain refinement, while also affecting the sintering behaviour.
