Ring of Fire Brazing Filler Metal HARRIS

Ring of Fire is based on Stay Silv 15 brazing filler metal and is commonly selected for brazing copper connections, particularly in air conditioning and refrigeration systems. Its wide melting range allows operators to fill loose joints and cap around finished connections, while heating above the liquidus temperature enables the alloy to penetrate tight joints effectively.

The alloy can also be used to braze brass components when suitable brazing flux is applied. It is generally suitable for copper and low nickel copper alloys containing up to approximately 10% nickel.

However, it is not recommended for brazing steel or other ferrous metals because of reduced joint ductility. Phosphorus-containing alloys should also not be used where joints are exposed to sulfur or sulfur compounds during service.
