| Kester 48 Activated Rosin Flux for cored solder wire was developed for
lead-free applications to enable soldering of most common metals. Kester
48 has performance characteristics far exceeding standard RA fluxes.
Kester 48 builds on the performance of its predecessor Kester 44 with
“instant-action” wetting to provide fast and reliable solder joints.
Kester 48 is available in a wide variety of alloys, wire diameters
and flux percentages. For most applications, Sn63Pb37 or
Sn96.5Ag3.0Cu0.5 is used. Consult the alloy temperature chart in
Kester’s product catalog for a comprehensive alloy list.
The standard wire diameter for most applications is 1.00mm (0.031in).
Wire diameters range from 0.25 - 6.00mm (0.010 to 0.250in). A "Standard
Wire Diameters" chart also is also included in Kester’s product catalog.
The amount of flux in the wire dictates the ease of soldering for an
application. For most applications, core 66 (3.3% flux by weight) is
recommended.
Other core sizes, 50 and 58, (1.1% and 2.2% respectively) are
available. Kester 48 is packaged on spools of different sizes to
accommodate a variety of applications. |
