Bismuth in solder wave

Bismuth in solder wave | 6 June, 2000

I have 25#'s of bismuth in my shop. I wanted to add some to my 63/37 till it was eutectic. This would allow me to lower the waves temp. Can I do this and still meet standards? Also would it make the solder joints to brittle and would discoloration be an issue? Jeff Sanchez
