EXPERIMENTAL INVESTIGATION OF TIG-WELDED ALUMINIUM 7075 JOINTS: WELD APPLICATION & THERMAL PROPERTIES

Aluminium 7075 is a high-strength aluminium alloy primarily composed of zinc, with magnesium and copper as key elements, offering exceptional mechanical properties and corrosion resistance. Widely used in aerospace, automotive, marine, and defence industries, it stands out for its excellent strength-to-weight ratio, making it ideal for aircraft structures, automotive components, and high-performance bicycles. In aerospace, its lightweight yet high tensile strength (up to 570 MPa) enhances fuel efficiency while ensuring structural integrity. The automotive sector benefits from its durability and resistance to fatigue, making it suitable for suspension components and performance parts. Aluminium 7075 offers a significant weight reduction without compromising mechanical strength, supporting advancements in lightweight engineering and sustainability.
