In general terms, dezincification, also known as the leaching of zinc, is a chemical process which involves the selective loss of zinc from an alloy. Specifically, it's an electrochemical reaction between zinc and certain chemicals which are found in water, which results in a spongy, weak layer of copper on the surface of the metal.

Dezincification-resistant (DZR) brass can help prevent corrosion from negatively affecting various components, including valves used in a number of applications. Although many applications use valves and other fittings made from normal brass alloys, certain impurities could cause a type of corrosion known as dezincification.

The term stands for Dezincification Resistant. It means that DZR brass can avoid dezincification. So, DZR valves are strongly resistant to a severe form of corrosion. DZR brass valves are perfect for long-term use without damage. It is more effective than regular brass. We use these valves widely for bathroom fitting purposes and many more.

DZR, or dezincification-resistant brass, is a special type of copper alloy that has been specifically designed to resist corrosion better than standard brass. It contains a higher percentage of zinc than standard brass and can withstand much harsher environments without corroding or developing pinholes on its surface.

Dezincification is a corrosion process, caused by the contact with water, which selectively removes zinc from the copper alloys, leaving behind a porous and copper-rich structure with reduced mechanical strength. Dezincification-resistant (DZR) brass contains additional elements which are able to inhibit this process and - particularly for the hot-formed pieces - presents a controlled.
