“…In recent years, many researchers have investigated the microstructure and properties of Cu/Al joints by using refill friction stir spot welding, electric current-assisted ultrasonic welding, and ultrasonic dynamic stationary-shoulder friction stir welding and other techniques [5][6][7][8][9][10][11], and these new processing methods can improve the quality of Cu/Al joints. However, these techniques are complicated and difficult to apply quickly.…”

Zn-Al alloy with the addition of Al (5–25 wt.%) was fabricated into as–cast and rod–shaped alloys. SEM/EDS and XRD technology were used to examine the impacts of the Al–element content on the alloys’ microstructure, mechanical characteristics, electrical conductivity, wetting ability, and corrosion resistance. The findings demonstrate how the Zn-Al alloy’s microstructure is dramatically altered by the different additions of the Al content. When the Al content reaches 15 wt.%, the eutectoid structures of the as–cast Zn-Al alloy are the finest, and the microhardness and tensile strength of the extruded–state alloy reach their maximum and exhibit the best corrosion resistance. The spreading area of the Zn-15Al solder alloy achieves its maximum on the 6061 Al plate, while it reaches its minimum on the T2 Cu plate. Furthermore, the electrical resistivity of the Zn-Al alloy continuously decreases as the Al content increases.
