Bi-Sn Solder
Bi-Sn Solder
An alloy of bismuth and tin that contributes to reducing the environmental impact of electronic devices as a lead-free solder. The eutectic composition (Bi57%/Sn43%) has a melting point of 138 °C, lower than lead-based solders, making it ideal for joining heat-sensitive components. Bismuth's artistic iridescent luster merges with tin's flexibility to form a quiet bridge-builder.
