Definition of dezincification in US English:



  • A form of corrosion and weakening of brass objects in which zinc is dissolved out of the brass alloy.

    • ‘Alloys above 15% Zn need a stress-relieving heat treatment to avoid stress corrosion and, under certain conditions, can be susceptible to dezincification.’
    • ‘Alpha-brass strip is not usually arsenical since it is mostly used in situations where dezincification does not occur or is not significant.’
    • ‘It was determined that the brasses with high zinc content were the ones that suffered dezincification when exposed to aggressive water.’
    • ‘Tin additions significantly increase the corrosion resistance of some brasses, especially resistance to dezincification.’
    • ‘The material will obtain a deep dezincification, since the dezincification will follow the long beta-phase bands.’
