2. Solder alloys - Wikipedia

   en.wikipedia.org/wiki/Solder_alloys

   Silver content reduces solubility of silver coatings in the solder. Not recommended for gold. [12] Forms a eutectic phase, not recommended for operation above 120 °C. Pb 80 Sn 18 Ag 2: 252: 260 [16] Pb: No: Used for soldering iron and steel [28] Pb 54 Sn 45 Ag 1: 177: 210: Pb: exceptional strength, silver gives it a bright long-lasting finish ...

3. Solderability - Wikipedia

   en.wikipedia.org/wiki/Solderability

   Nickel silver Beryllium copper: High thermal conductivity of these metals requires high heat input during soldering. Oxidizes quickly so proper flux must be used. Fair: Carbon steel Low alloy steel Zinc Nickel: Solder joints become brittle in sulfur-rich environments. Avoid higher temperatures in the presence of lubricants (which contain sulfur ...

4. Flux (metallurgy) - Wikipedia

   en.wikipedia.org/wiki/Flux_(metallurgy)

   Stainless steel is a material which is difficult to solder because of its stable, self-healing surface oxide layer and its low thermal conductivity. A solution of zinc chloride in hydrochloric acid is a common flux for stainless steels; it has however to be thoroughly removed afterwards as it would cause pitting corrosion .

5. Soldering - Wikipedia

   en.wikipedia.org/wiki/Soldering

   Extra-easy solder contains 56% silver and has a melting point of 618 °C (1,145 °F). Extra-hard solder has 80% silver and melts at 740 °C (1,370 °F). If multiple joints are needed, then the jeweler will start with hard or extra-hard solder and switch to lower-temperature solders for later joints. Silver solder is somewhat absorbed by the ...

6. Black oxide - Wikipedia

   en.wikipedia.org/wiki/Black_oxide

   Black oxide or blackening is a conversion coating for ferrous materials, stainless steel, copper and copper based alloys, zinc, powdered metals, and silver solder. [1] It is used to add mild corrosion resistance, for appearance, and to minimize light reflection. [ 2 ]
