2. Flux (metallurgy) - Wikipedia

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

   Rosin used as flux for soldering A flux pen used for electronics rework Multicore solder containing flux Wire freshly coated with solder, held above molten rosin flux. In metallurgy, a flux is a chemical reducing agent, flowing agent, or purifying agent. Fluxes may have more than one function at a time.

3. Solder alloys - Wikipedia

   en.wikipedia.org/wiki/Solder_alloys

   Lies between soft solder and silver brazing alloys, thereby avoiding damage to critical electronics and substrate deformation and segregation. Best solder for aluminium wire to Copper busses or copper wire to aluminium busses or contacts. [69] UNS#: L91090 Sn 85 Zn 15: 199: 260 [69] Yes: No

4. Fusible alloy - Wikipedia

   en.wikipedia.org/wiki/Fusible_alloy

   Lies between soft solder and silver brazing alloys, thereby avoiding damage to critical electronics and substrate deformation and segregation. Best solder for Aluminum wire to Copper busses or Copper wire to Aluminum busses or contacts. [19] UNS#: L91090 Sn 92.0, Zn 8.0: 199 °C (390 °F) no: Tin foil: Sn 100: 231.9 °C (449.4 °F) (yes) Sn99 ...

5. Soldering - Wikipedia

   en.wikipedia.org/wiki/Soldering

   Properly done, the iron heats the parts to be connected, which in turn melt the solder, guaranteeing adequate heat in the joined parts for thorough wetting. If using solder wire with an embedded flux core, heating the solder first may cause the flux to evaporate before it cleans the surfaces being soldered.

6. Filler metal - Wikipedia

   en.wikipedia.org/wiki/Filler_metal

   A hard, but more expensive and sometimes brittle, facing alloy is deposited onto the wear surfaces of mild steel tools. Four types of filler metals exist—covered electrodes, bare electrode wire or rod, tubular electrode wire, and welding fluxes. Sometimes non-consumable electrodes are included as well, but since these metals are not consumed ...

7. List of brazing alloys - Wikipedia

   en.wikipedia.org/wiki/List_of_brazing_alloys

   Used with flux. Unsuitable for vacuum brazing due to high zinc content. Worse corrosion resistance due to higher alloying. Tendency to liquation, has to be heated rapidly through the melting range. Grayish-white color. 4: 10: 76: 10: Zn 98 Al 2: 382/392 [4] – AL 802. General purpose filler metal for aluminium soldering/brazing with a torch ...
