I work in a UHV chamber typically around low 10-9 Torr. Can I use hard
silver solder for parts to be put into this chamber? The composition
of this solder is 56% Ag, 22% Cu, 17% Zn. From what I know, Ag and Cu
in a UHV environment is OK. But is Zn likely to outgas a lot? Anyone
have any experience with this?
FYI, the silver solder our machine shop uses is form Harris Products
Group, Safety-Silv 56
