At The Bicycle Academy we use SIF NO43 for capillary brazing in circumstances when a fast flowing filler material is required, for example when brazing a lugged joint.

A highly-ductile, fast-flowing, cadmium-free 55% silver brazing filler metal. It can be used with a range of heat sources. It also offers a combination of low melting temperature and excellent flow characteristics. Use with SIF silver solder flux.
