armack Soft solder flux cored lead free wire BF26-3

Wire made of S-Sn95Ag4Cu1 DIN EN ISO 9453 with flux type DIN EN 29454-1 1.1.2.B (FSW 26) 2,5 % flux content. Melting range: solid 217°C, liquid 219°C. Flux type DIN EN 29454-1 1.1.2.B contains colophony and a halogen containing activator. This flux has got an excellent oxide releasing effect and an optimal solder extension. The residues are not corrosive with non-iron metals and can therefore remain on the soldering joint in most of the cases.
