Aluminium Metal Alloy 7075 T7451 Sheets

Analyzing our product quality and growth of demand, we are engaged as trader, supplier and exporter of Aluminium Alloy 7075 T7451 Sheets in Mumbai, Maharashtra, India. The aim of the present work is to investigate on the mechanical and microstructural properties of dissimilar 2024 and 7075 aluminium sheets joined by friction stir welding (FSW). The two sheets, aligned with perpendicular rolling directions, have been successfully welded; successively, the welded sheets have been tested under tension at room temperature in order to analyse the mechanical response with respect to the parent materials. The fatigue endurance (Sa N) curves of the welded joints have been achieved, since the fatigue behaviour of light welded sheets is the best performance indicator for a large part of industrial applications; a resonant electro-mechanical testing machine load and a constant load ratio R=I min/I max =0.1 have been used at a load frequency of about 75 Hz. The resulted microstructure due to the FSW process has been studied by employing optical and scanning electron microscopy either on a as weldeda specimens and on tested specimen after rupture occurred.
