- Dezincification of brass is a particular type of corrosion occurs in th presence of sea water.
- The attack remives zibc from the alloy , leaving porous copper which is soft. The problem is marked by a patch of copper color on the brass.
- Dezincification is inhibited in brass which are intended for sea water contact, by additives of a very small amount of arsenic or other element.
