Brazing and Soldering Guide: Filler Metals, Torch and Furnace

Brazing and Soldering Guide: Filler Metals, Torch and Furnace

Short answer: Brazing and soldering use a lower-temperature filler to join metals without melting the base, from tin-based solder for electronics to silver and copper-phosphorus alloys for plumbing and steel, with consumables in our Copper Supplier and the related process in our Metal Welding Guide.

Brazing vs Soldering

Both use capillary filler below the base melting point; soldering is below 450 C for electronics and plumbing, brazing is hotter for stronger joints, with the wider joining view in our Metal Welding Guide.

Common Filler Metals

Copper-phosphorus and silver alloys join copper and steel, while tin-based SAC solders serve electronics, with copper base in our Copper Supplier page.

Torch, Furnace and Induction

Manual torch brazing suits repair, furnace and induction give clean, repeatable production joints on brass and steel assemblies.

Quality and Certification

Confirm joint integrity and alloy with our Quality Inspection Guide and lot documents per our Mill Test Certificate Guide.
