Product information

675Sn Alloy with high Phosphorus and Tin content which is recommended for copper brazing. Tin (Sn) lower the melting point, increase fluidity and enhance good wetting properties. Due to its low melting alloy requires a rapid heating cycle to ensure that the elements do not separate through liquation. Excellent fluidity and low melting arrange. This alloy is also recommended for narrow gap due to its good capillary action. When brazing brass or copper to brass you need a separate flux, Meltolit 770.

This alloy is not recommended to be used for media containing sulphur. Also it is not allowed to use for joining steels (Fe) or materials containing Iron (Fe), Nickel (Ni) or Cobalt (Co) as it will form brittle phase in the joint.
