Brazing filler metals for low metal ion leaching in drinking water applications
Maintaining optimal water quality with the right filler metals
Brazed components can unfortunately introduce metal ions to water, but Höganäs has discovered that using certain brazing filler metals can all but eliminate leaching issues in drinking water applications.
Höganäs has tested the amount of metal ion leaching from various brazing filler metals that are relevant for drinking water applications, particularly for brazed plate heat exchangers. The tests highlighted that Höganäs’ iron-based brazing filler metals BrazeLet® F300-20 and BrazeLet® F86 offer significant technical advantages in terms of lower or no significant metal ion leaching to drinking water.
