Abstract
Feasibility of using recycled-Aluminum (re-Al) as reinforcement particulates in Sn-0.7Cu is assessed by powder technology method, whereby re-Al particulates are produced from discarded aluminum beverage cans. This paper focuses on the intermetallic compound (IMC) formation study between the fabricated solder composite on Cu-substrate. Throughout this study, four different composition of Sn-0.7Cu/re-Al (0.0, 3.0, 3.5, 4.0 wt.%) were studied. X-ray diffraction (XRD) was used to analyze the IMCs phase formation between the interfaces. New IMC phase of Cu9Al4 was detected beside Cu6Sn5 and Cu3Sn in the composite solder samples. However, Sn-0.7Cu/3.0re-Al showed least formation of brittle IMCs compared to the monolithic solder.
