Safety-Silv® 40 Brazing Alloy HARRIS

Safety-Silv® 40 brazing filler metal is formulated for brazing copper, brass, and steel components across industrial and HVAC applications. Its melting range allows effective use where joint clearance cannot be tightly controlled while maintaining good alloy flow characteristics.

The alloy is often selected as a cost-saving alternative to traditional higher silver content brazing alloys while still delivering dependable joint performance. It is suitable for fabrication, maintenance, and production brazing tasks requiring consistent alloy flow and joint reliability.

Safety-Silv® 40 is also available as a flux-coated rod, where the extruded flux layer simplifies application by eliminating separate fluxing. However, because the coating provides a limited amount of flux, this option is typically best suited for smaller assemblies.
