BRAZING ALLOYS - COPPER/PHOSPHORUS
|
|||||||
|
Copper-flo™ is a range of brazing metal fillers recommended for the fluxless brazing of copper. They have a lower ductility than Silver/Copper/Phosphorus
products. Copper-flo™ should not be used on nickel or iron containing metals, including all grades of steel, as a brittle joint will result.
Stan-fos™ is a very free flowing filler metal, that produces a good surface finish on joints, however, it has low ductility and requires the use of a flux.

BRAZING ALLOYS - SILVER/COPPER/PHOSPHORUS
|

|
Sil-fos™ & Silbralloy™ are a range of brazing metal fillers recommended for the fluxless brazing of copper. On brass, bronze, and other copper alloys, a flux, such as Easy-flo™ or Tenacity™ No.4A is required.Sil-fos™ & Silbralloy™ should not be used on nickel or iron containing metals, including all grades of steel, as a brittle joint will result.
Sil-fos™ is the most ductile of this range, Silbralloy™ can be used instead of Copper-flo™ when a low cost filler with higher ductility is required.
