Pro-Braze718FCP is a flux coated 4047 filler metal shim/strip used for joining aluminum and aluminum alloys. Pro-Braze 718FCP is the eutectic aluminum/silicon composition that melts over the narrow temperature range of 577C to 582C (1070F-1080F). Normal brazing temperature is 582 to 604C (1080F-1120F).
Pro-Braze 718FCP is coated with NOCOLOK® flux, a non-corrosive flux for aluminum. The flux coated filler metal shim preform is commonly used on automatic flame brazing machines. Pro-Braze718FCP is also used in atmosphere furnace, torch or induction brazing processes for joining a wide variety of aluminum alloys. No post braze cleaning operations are required. The flux and its residues are non-hygroscopic and non-corrosive.
Pro-Braze 718FCP conforms to:
AA 4047; AWS A5.8 BAlSi-4; AMS 4185; Alcoa 718
Nominal composition: 88% Al-12% Si
Melting Point - 577C - 582C (1070F-1080F)
NOCOLOK® Flux is a mixture of potassium fluoroaluminates
Corresponding to the general formula K1-3AlF4-6
Melting Point – 565 – 572C (1050F-1062F)
Pro-Braze 718FCP replaces the use of flux and 718 braze rings. Cleanliness of assembly area is enhanced due to the minimum amount of flux use. Pro-Braze 718FCP is also a substitute where corrosive flux alloy paste is in use for torch application. Waste water treatment is eliminated.
Pro-Braze 718FCP is available in coil or as custom-sized preforms.
