DZR (Dezincification Resistant) or DR Brass is a type of brass used for manufacturing, which gives resistance to dezincification corrosion. Products that offer Dezincification Resistant properties will often be marked with the "DR" mark, as above. What Is Dezincification? Brass is a widely used metal alloy, made of copper and zinc.

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 INTABALL LEVER VALVE

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.

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.

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.
