However, such washing operations were conceived for the surface conditioning of alloys with lead percentages above 2% and they are still used as a generic solution despite of the brass market tending towards low-lead-content alloys (0.09% \u2013 0.2% in alloy).<\/p>\n<p>The main problems stemming from de-leading not correctly targeted towards the base material to be treated translate into:<\/p>\n<ul>\n<li>Accelerated oxidation<\/li>\n<li>Colour change (from bronze brown up to intense copper pink)<\/li>\n<li>Colour inhomogeneity<\/li>\n<\/ul>\n<p>Thus, DNG (De-leading next gen) is a chemical conditioning for brasses and copper alloys created for effectively acting on low-lead content alloys too leaving the aesthetic features of the component intact and guaranteeing the compatibility thereof at contact with potable water and food products.<\/p>\n<p>Main features:<\/p>\n<ul>\n<li>Base material intact after conditioning<\/li>\n<li>Reduction of lead release in water and food products<\/li>\n<li>Colour duration over time<\/li>\n<li>The conditioning solution is free of fluorides and nitric acid<\/li>\n<\/ul>\n<p>Compliance
