DZR
DZR (Dezincification Resistant) Brass is a type of brass which gives resistance to dezincification corrosion
What is Dezincification?
Brass is mainly made of copper and zinc. In certain circumstances, when exposed to particular combinations of pH and concentrations of chlorides it can experience a severe form of corrosion known as dezincification. This is where the zinc dissolves out of the brass, weaking and compromising the mechanical properties of the alloy.
In relation to HVAC applications, dezincification can result in system failure by causing leaks, blockages or even ruptures. It is therefore rightfully a major consideration when it comes to system design.
