| Abstract | ||||
| Due to the dangerous health effects of lead many candidates lead free solder alloys are developed for many welding applications. Sn-0.7Cu based alloys one of the most candidates for electronic applications this may be for the melting temperature and the low cost in this paper rotating magnetic field of 0.5T used with addition of (.05 co wt% ) and (.5 co wt%) where the mechanical testes show strength improvement between 32-44 Mpa the tensile properties have been tested at different temperatures and different strain rate, X-ray diffraction(XRD) , optical microscope were employed to analyze the microstructure of Sn -0.7 Cu-.05 Co wt% and Sn -0.7cu -0.5Co Wt% before and after applying the rotating magnetic field(RMF), respectively and the phases were identified by energy-dispersive spectroscopy (EDS) and Differential scanning calorimetry (DSC) was used to investigate the melting temperature of which rang from 230-233 0c. | ||||
