Stay Silv 18 is low melting temperature copper phosphorus silver braze alloy. It is designed for brazing copper and brass. Its melting temperature and narrow melting range allow shorter heating cycles and increased part output. Clearance of 0.002-0.004" is suggested.

Stay Silv 18 is an attractive lower cost replacement for high silver content filler metals often used for brazing brass. Its low melting temperature reduces the likelihood of base metal melting. Brazing brass or bronze requires use of Harris Stay Silv ® white brazing flux.

Stay Silv 18 is not recommended for brazing steel or other ferrous base metals. The phosphorus content promotes formation of a low ductility intermetallic with the ferrous base metal.

CORROSION RESISTANCE
Generally similar to the copper base metal, but phosphorus containing alloys, including Stay Silv 18 should not be used if the braze is exposed to sulfur or sulfur compounds in service.

AVAILABLE FORMS
Standard wire diameters in coils, rods, spools, and rings.

RECOMMENDED FLUX:
No flux is required for copper brazing. For brazing brass or copper to brass use Stay-Silv ® white flux.
