Web1 Jul 2015 · In addition, Sn metal is stable at and above room temperature, malleable and weldable with copper (Cu) and aluminium (Al). Moreover, it has low electrical resistivity, a low-melting point (231°C) and high-surface tension (0.544 N/m). Websystem is installed on a continuous production line as the Al/Al-Sn/Al/steel strip passes a fixed inspection point. Strips are used to manufacture engine sliding bearings in the automotive industry due to the ideal combination of properties of Al-Sn alloy and steel [1]. Figure 1(a) shows a micrograph of the four-layered Al/Al-Sn/Al/steel structure.
