Medical and Domestic Applications

Brazing of cookware

Aufhauser brazing filler metal is used for joining copper disks to the bases of saucepans. It can be applied as a flux coated powder or powder / flux blend which is sprinkled onto the copper disk prior to assembly and heating. Lack of water or other solvents means that a good level of alloy cover is achieved.
