Hi
My question relates to electronics soldering, where the main metal in the solder is Sn, with small amounts of Ag and/or Cu
If a rod of Cu, Ag, or Au is placed in molten Sn, which of the rods would melt away fastest?
Is there a threshold temperature up to which the solid metals won't melt/alloy? Or do they start alloying as soon as they are placed in the molten Sn?
For solid Cu or Ag, if some of the different metal is already alloyed with the molten tin, how will it change the alloying process?
And most importantly (for my curiosity), why?
Thank you,
Archie
