The DS22 500G REEL is a rosin based cored Solder Wire made of 99.3Sn0.7Cu alloy. Multicore 362 and 366 cored wire is manufactured with a range of flux contents. Although users will normally be using products with a nominal flux content of 3%. Multicore 362 and 366 cored wire is available in a variety of alloys conforming to J-STD-006 and EN 29453 or alloys conforming to similar national or international standards. The alloys used for Multicore flux cored solder wire conforms to the purity requirements of the common national and international standards. Multicore 362 and 366 solid flux leave dry and non-sticky residues. In use its odour is typically that of rosin fluxes. Multicore flux cored solder wires provide fast soldering on copper and brass surfaces as well as solder coated materials. Activity of the halide activated versions on nickel is also good depending on the state of oxidation of the nickel finish.Good wetting on most common surfacesNon-corrosiveFast solderingRosin basedHalide activatedTwo activity levels, Multicore 362 for general work and Multicore 366 for more difficult surfacesFlux Type: RosinExternal Diameter: 0.71mmMelting Temperature: 183°CWeight: 500g
