Can steel wire be soldered?
Similarly, can stainless steel wire be soldered?
Unlike other metals, stainless steel is very difficult to solder. It has a thick oxide layer that prevents melted solder from sticking to its surface. While the job is a bit more complicated than regular soldering, you can successfully solder stainless steel with a few simple steps.
Subsequently, question is, can copper be soldered to steel? Technically, you can either braze or solder, though you cannot braze with solder or solder with brazing rods. But you can attach copper to steel with silver solder using a propane torch, and call it whatever you like. Apply a coating of flux to the steel where you are going to solder on the copper.
Similarly, you may ask, what kind of wire can be soldered?
Basically all metals can be soldered, but we are looking for a low melting point soft solder and a flux. With the soft solders and a zinc chloride flux (most common), these metals will bond very easily: copper, tin, and brass. These metals will NOT bond: Iron, stainless steel, steel, and aluminum.
What metal Cannot be soldered?
Stainless steel and high alloy steel have a low solderability because the chromium alloying element creates oxides that require aggressive fluxes. The only way that the final category of metals can be soldered is by pre-plating them in a metal that is solderable.
