Sn50Pb50 Pb flux core tin lead solder wire
Sn50Pb50RA water-soluble core wire is a very low halide（<1000ppm）, water-soluble flux cored solder.the flux core type can be divided into 1.5%,2.0%.3.0% Its post-soldering residue is water-soluble and can be easily cleaned with DI water. Our water-soluble core wire is recommended for use in any hand soldering application where high flux activity is desired.

Feature:

. Fast welding speed, superb wettibility,terrific expandability.
 The tin-lead wire added the activated core 2%,featuring fast melting speed, superb wettibility,terrific expandability.Thereby it can offer distinguished soldering performance.

.Wonderful electrical conductivity, no core breakage and no splash.

.High temperature anti-oxygen

.Satisfactory soldering joint and favorable fluidity.

Solder joints are filled, and firm. Both RA and RMA are made in complicance with IPC J-STD-006 and JIS Z3283 class AA standards. All these solder flux can be dissolved in solvent, featuring a little smoke and very few splatters.

.Flux content ranges from 1.5% to 3.5%, while the wire diameter can be opatinal avove 0.35mm(0.4mm,0.5mm,0.8mm,1.0mm…)
