The dezincification test applied in our fittings in according to the produres stated in ISO6509:1981(Corrosion of metals and alloys - Determination of dezincification resistance of brass) , After repeated rigorous tests, the depth of dezincification for our DZR brass alloy is now controlled under 50um. As a result, the life span of our DZR brass alloy fittings is significantly lengthened. Our DZR brass fittings have already been usde in freshwater supply systems in Europe, Australia, United states and China.
