Solder strength depends on the type of solder and the conditions of the joint, but typical 60/40 (tin/lead) solder has a shear strength around 5700 psi and tensile strength about 6400 psi. In practical tests, soldered joints can often be as strong or stronger than the wire or metals they connect, sometimes supporting significant weight without failing. However, solder is generally used for electrical connections rather than structural strength, as its mechanical properties are inferior to welding or brazing. Silver solder, used in jewelry or specialized applications, can reach tensile strengths between 10,000 to 70,000 psi, while brazing typically exceeds 130,000 psi. In summary:
- Standard 60/40 solder shear strength: ~5700 psi
- Standard 60/40 solder tensile strength: ~6400 psi
- Silver solder tensile strength: 10,000 to 70,000 psi
- Brazing tensile strength: >130,000 psi
- Solder joints often fail in the substrate material rather than the solder itself in well-made joints
- Solder is good for electrical and light mechanical applications, but not for heavy structural use.
Would elaboration on solder types or usage contexts be helpful?
