MAIN CHARACTERISTICS
Anti-dezincification alloy with a low lead content. Its high copper content and a presence of As that guarantee, after the thermal solubilzation of beta phase, a very strong resistance in contact with aggressive waters, above all for the north American market of components in contact with potable water. This alloy is in fact certified to NSF/ANSI 371 standard.
