Aluminium Alloy 7075-t651 Flat

With creditable success in our business activities, we are exclusively engaged as trader supplier and exporter of Aluminium Alloy 7075-T651 Flat in Mumbai, Maharashtra, India.
Friction stir welding (FSW), a new welding technique invented at TWI, was used to weld 7075 T651 aluminum, an alloy considered essentially unweldable by fusion processes. This weld process ex-posed the alloy to a short time, high-temperature spike, while introducing extensive localized defor-mation. Studies were performed on these solid-state welds to determine mechanical properties both in the longitudinal direction,i.e., within the weld nugget, and, more conventionally, transverse to the weld direction. Because of the unique weld procedure, a fully recrystallized fine grain weld nugget was developed. In addition, proximate to the nugget, both a thermomechanically affected
zone (TMAZ) and heat affected zone (HAZ) were created. During welding, temperatures remained below the melting point and, as such, no cast or resolidification microstructure was developed. However, within the weld nugget, a banded microstructure that influences room-temperature fracture behavior was created. In the as-welded condition, weld nugget strength decreased, while ductility remained high.
