What is the percentage of tin in soft solder? Correct Answer 63%

Explanation:

  • Soldering is the process by which metallic materials are joined with the help of another liquified metal (solder)
  • Soldering can be classed as soft soldering and hard soldering.
  • The process of joining metals using tin-lead solders which melt below 420°C is known as soft soldering
  • The process of joining metals using hard solders consisting of copper, zinc, cadmium, and silver which melt above 600° is known as hard soldering
  • The eutectic alloy of tin-lead solder is a mixture of 63% tin and 37% lead. 63/37 solder melts at 183°C
