De-alloying corrosion, known as ”Dezincification,“ was effectively eradicated from valve products in the 1950s.
Today, however, this problem has returned with the increased use of high-zinc alloys (commonly referred to as
‘Yellow Brass’) in forged and cast valves typically produced outside the United States.
Dezincification selectively removes zinc from the alloy, leaving behind a porous, copper-rich structure that has little mechanical strength. The
physical attributes of an in-service valve with dezincification includes a white powdery substance or mineral stains on its exterior surface.
What’s the cure? On all bronze valves the metal components in the waterway must not contain more than 15% zinc in their chemical makeup.
As a standard NIBCO bronze pressure-rated valves are made to be “Dezincification Resistant,” which is a seal of quality and longevity.
