Title:
PROVISION OF WATER-CARRYING COMPONENTS MADE FROM BRASS ALLOYS WHICH RELEASE REDUCED QUANTITIES OF METAL IONS
Document Type and Number:
WIPO Patent Application WO/2009/062593
Kind Code:
A9
Abstract:
In a process for producing or for providing water-carrying components made from brass alloys, such as fittings and the like, which release reduced quantities of metal ions during use, a copper oxide layer is formed on at least parts of at least those surfaces of the components which in use come into contact with water. In particular, the process can be carried out even in those cases in which the decorative surfaces of the respective components have already been chrome-plated when the process is carried out.
