Alloys can be produced as solid or flux cored wire (Flux content 0.5-3.5%), bars or pre-forms. ST400 and ST300 are recommended for use in environments where ‘soft’ water would corrode conventional tin-lead solders. The Silver containing alloys resist Silver migration when soldering silver plated components. Special Alloys can be produced upon customers’ request.
