Cu–Sb Solder Alloy by Combustion Synthesis: Structural Characterization and Magnetic Properties

Lead-free Cu–Sb solder alloys of nominal composition Cu–20 at % Sb were fabricated by SHS and electrothermal explosion (ETE) and characterized by XRD, SEM, and vibrating sample magnetometry (VSM). Combustion products were found to represent a mixture of δ-Cu11Sb3, β-Cu3Sb, and Cu. The ETE and SHS methods were recommended as a facile route to synthesis of Cu–Sb intermetallics.
