Arc Welding Service

CATEGORY

Brazing

TYPE

3% silver containing cadmium free soft solder alloy

APPLICATIONS

Soldering applications in cooling, automotive and electronic industry. Suitable for food applications due to the absence of Cadmium. Suitable for working temperatures up to 100ºC.

PROPERTIES

Used for strong brazing joints of uneven junctions with excellent flowing properties. Offers much better mechanical characteristics compare to standard PbSn soft solders. Excellent results are obtained on stainless steel with our "ST" flux.

CLASSIFICATION

EN ISO

9453: S-Sn97Ag3

SUITABLE FOR

Steel, stainless steel, brass, copper, galvanised steels, Sn plated steels etc.

APPROVALS

CE approved, RoHS
