Abstract :Abstract Electrical wires are used in many applications with increasing amounts especially in constructions and houses. These conductive wires are mainly manufactured from 99.9% (by weight) electrolytic copper with restricted amounts of other minor elements. Copper wires are joined by soldering operations in aim of high electrical conducting efficiency. Soldering flux usage is a must in soldering where higher corrosion resistance with satisfactory adhesion property is in concern for increasing joining quality. Soldering flux exhibits an important role related with adhesion and corrosion properties of the joints. In this study, three different types of soldering fluxes were used in soldering of electrical copper wire. Corrosion test is applied on soldered wires with also unsoldered raw copper wire by immersing in 20%NaOH solution by 96 hours of duration time. Comparison of corrosion resistance of samples is investigated by weight loss principle according to ASTM G1 standard document. The highest corrosion resistance was observed on samples joined with a solder flux of having zinc and ammonium chloride while the least corrosion resistance was observed in samples joined with flux containing halides.
