Different composition of (Sn -Bi) powder of (800-100) μm, grain size were achieved. Three types of alloy were fabricated by melting under (350°C) in inert atmosphere. X-ray diffraction indicated the formation of (Sn-Bi) alloys. Melting points were conducted. Optical micrographic investigated to study the main structure characterization for all fabricated alloys. Hardness test reflect the ductile form for all the three alloys with a remarkable value of 26 HRB for the alloy 40 wt.% Sn-60 wt.% Bi.
