Copper soldering iron for capillary soldering CHEM-WELD 550

CHEM-WELD 550

Universal brazing compound, Ag 15%

Standard:

DIN 8513: L-Ag15P

AWS A 5.8: B-CuP5

EN 1044: CP 102

For brazing copper and copper alloyed materials. Recommended for applications where high quality, strength, ductility, wettability and capillary action are required. Copper can be soldered without the use of flux, low melting point, suitable for soldering small gaps from 0.05 to 0.15 mm, contains high amounts of silver for good electrical conductivity, high strength and ductility. For high quality soldering of copper pipes, control valves in cooling systems, electrical connections, air conditioning, hot and cold water pipes, steam systems, heat exchangers, current conductors, fittings, etc. We recommend flux 110. Designs round or square.
