Soft-solders
Alloys based on Tin for Soft-Soldering.
Lead bearing alloys have particular Health and Safety limitations in applications and uses.
Lead-free alloys, compliant to RoHS regulation, are available.
Available as ingots, bars, sticks, wires and flux-cored wires.
Some alloys are also available in paste: see Powders Pastes.
Flux cored wires are available with different cores for various applications, as follows:
SN1 EN 29454-1 3.1.1 For Stainless Steel
SN35 EN 29454-1 2.1.2 For Aluminium
SN6 EN 29454-1 2.1.3 For Electromechanics

BRAZING PREFORMS: MORE QUALITY, LOWER COSTS
Brazing preforms are consumables for brazing obtained both from wire and strip, realized in various shapes such as discs, rings, arc rings etc.
The use of preforms drastically reduces scraps and rework and improves quality of final results.
