I believe tin simply oxidizes before lead.

|TechNetters, is tin preferentially depleted from the solder
|pot in wave soldering?  If so, what is the mechanism?  My
|recollection is that I learned some months back that, left
|unadjusted, tin content of a solder pot will slowly drop.
|Thanks for any comments.
