Tin/Lead/Antimony Alloy Coil (Sn60/Pb39/Sb1)

Tin Lead Antimony Alloy Coil (Sn60/Pb39/Sb1) combines the low melting point and excellent wetting of tin-lead solders with the hardness and creep resistance imparted by antimony. This composition improves mechanical strength and thermal fatigue performance, making it suited for heavy-duty soldering, electrical bus bar joining, and heat-resistant coatings. Industries such as automotive electronics, aerospace, and industrial power systems benefit from its durability in demanding conditions. Specific uses include soldering high-current connectors, producing wear-resistant coatings on contact surfaces, and reinforcing solder joints in high-vibration environments. In research, Sn60/Pb39/Sb1 coils are studied for phase stability, oxidation resistance, and microstructural control, ensuring performance consistency under prolonged thermal and mechanical stress.
