Sn20Pb80 Solder Wire is a specialized soldering alloy composed of 20% tin (Sn) and 80% lead (Pb). This combination provides a higher lead content, resulting in a melting range of approximately 183°C to 215°C (361°F to 419°F). It is particularly suitable for applications where high mechanical strength and excellent thermal conductivity are required, such as in plumbing, automotive, and certain industrial electronics.
The higher lead content increases the durability and robustness of the solder joints, making them more resistant to mechanical stress and thermal cycling. Additionally, the lower tin content reduces the risk of whisker formation, ensuring long-term reliability.
Sn20Pb80 offers a balanced composition that optimizes mechanical strength and reliability for specific applications requiring robust joints.
