Abstract

See full text

Aluminum parts, such as heat exchangers, with improved resistance towards corrosion caused by contact with stationary water or aqueous compositions can be obtained by addition of Li compounds to the flux used for brazing such parts. LiF and especially Li fluoroaluminates are very suitable. Another aspect of the invention concerns fluxes containing Li salts and their use for brazing of aluminum parts.
