Abstract
In this paper, we studied the structure and electrical properties of the alloy of composition Sn-9Zn-1Ag solder alloy as example of metallic materials that is used in electronic applications. The alloy exhibited three phase mixtures, tetragonal Sn as a solid solution and Zn phase and AgZn intermetallic compound. The lattice parameters, a, and C of the tetragonal Sn were also calculated. The ternary alloy exhibited Ohmic behavior. Also, we described its variation with temperature and determined the temperature coefficient of resistivity (TCR).
