BRAZING RODS AND FLUXES Unitor soldering and brazing alloys have been selected with versatility and ease of use in mind. In the industry there is a wide range of brazing alloys available for special applications, but a number of these are developed for special applications, and may be dangerous if used incorrectly. Many brazing alloys contain Cadmium or Phosphorous. These elements offer certain advantages with regard to price, because the silver content can be reduced without reduction of the capillary effect. Both elements, however, are dangerous or prohibited in applications frequently needed on board. Phosphorous is prohibited (by Norwegian regulations) on brass pipes and red bronze. Cadmium is extremely poisonous and must not be used on any piping or equipment carrying drinking water or food.

Unitor brazing alloys are all Cadmium free, and only the cast-iron brazing rod contains phosphorous. Unitor brazing rods may therefore safely be used as true general purpose filler material onboard. Each alloy has been selected to cover a wide range of applications. This reduces the number of alloys needed to be kept in stock

and gives the operator an easier choice.

Where practical flux-coated rods have been selected to ensure the best soldering/brazing properties. In addition a range of fluxes is supplied. They are designed specially for use with the Unitor alloys, either as addition to the flux coating on the rod, or with the un-fluxed rods. The soldering tin contains flux in ducts inside the solder. Apart from the soldering tin, which is supplied on a spool, all alloys are supplied in 500 mm lengths, which is a suitable length if unnecessary bending of the rod shall be avoided. Even though special care has been taken to ensure flexibility in the coating, excessive bending should be avoided to ensure that the coating remains undamaged. It is good economy to braze the remaining part of a rod to the next instead of discarding the stump Both rods and fluxes are supplied in sealed plastic containers for protection against humidity. The label on each container fully identifies the contents, and also gives basic information on application areas.
