SUPERFLOW® 96.5/3.5 Silver Bearing Solder has excellent strength with high elongation and vibration resistance for sound joints in many applications. With its low melting temperature and bonding of all the ferrous and non-ferrous alloys including stainless steel, nickel, copper tubing, brass, etc – this alloy will prevent distortion and loss of your base metal properties. On copper tubing it will give a stronger overall finished assembly than the typical braze alloys. Rosin cored Sn/Ag solder is used on electrical and electronics when lead free solder are required.
