What is hard soldering used for?

"Hard soldering" or "silver soldering" is used to join precious and semi-precious metals such as gold, silver, brass, and copper. The solder is usually described as easy, medium, or hard in reference to its melting temperature, not the strength of the joint.

  • Is solder as strong as welding?

    Properly brazed joints can be stronger than the pieces being joined, but are not as strong as welded joints. Brazing also has minimal effects on the two metal parts. Soldering is a low-temperature analog to brazing.
  • What is a soft solder used for?

    The most common solders used for soft soldering work are 60/40 or 50/50; these numbers are based on the percentages of tin and lead used to make the solder. Lead-free solder is made using a combination of metals, typically with a high concentration of tin and smaller amounts of silver and copper--never lead.
