Brazing filler metal is a frequent choice for brazing copper. It has a wide melting range which allows the operator to fill loose connections. It can be used to braze brass with the use of Stay-Silv® white brazing flux. Stay-Silv® 5 is not recommended for brazing steel or other ferrous metals. Medium-range alloys, Stay-Silv® 5 is useful primarily where fit-up cannot be tightly controlled.
