Silver Flux EasyFlo Flux Paste - 250g

A brazing flux suitable for use with silver brazing filler metals. Working range of 575-825C and can be used with silver brazing filler metals melting below 775C. Supplied in a 250gram jar.

Easy-flo™ Flux Paste is Johnson Matthey’s leading brand brazing flux. It is sold widely throughout the world and is recognised as one of the best flux paste available. It is very fluid at the bottom end of its working range resulting in early and extensive flux spread.

This ensures that the joint surfaces are well protected from oxidation at the earliest possible point of the brazing operation. This high level of fluidity also helps to reduce flux voids / entrapment in the joint, the low viscosity of the flux aiding its displacement by the brazing filler metal from the joint gap. Easy-flo™ Flux Paste has a working range of 550-800?C. It is suitable for use with silver brazing filler metals melting below 750?C

Working Temperature: 550-800°C

Conditions for use:
Flux paste should be brushed onto the joint surfaces before assembly. Further flux should then be applied externally either side of the joint mouth.

It is good practice to mechanically clean and degrease the joint surface before applying flux. Heat slowly and evenly to the brazing temperature, without local overheating. Use the flux as a temperature guide - it will become clear or opaque as brazing temperature is approached. If blackening of the flux occurs this is often a sign of insufficient flux, overheating or flux exhaustion.

The flux residues left after completion of the brazing operation are corrosive and should be removed. The residues for Easy-flo Flux Paste can easily be removed by soaking in hot water > 40°C for between 15 and 30 minutes. Any remaining residues can then be brushed off in running water.
