Our new Cu-Si-alloy for drinking water applications represents:

The choice of the most suitable alloy is one of the most important aspects for drinking water applications.

The chosen alloys and products have to meet technical and mechanical requirements as well as to be hygienically completely harmless.

The alloys and products applied are consequently tested regarding the migration of chemical components and the growth of microorganisms.

Due to the negative impact on our health the maximum value for lead in drinking water will be reduced to 10 µg/l starting as of December 1st, 2013.

is specially designed for the requirements of drinking water applications. This Cu-Si-alloy considers the legal requirements of the future as well as the important aspects regarding reliability, hygiene, healthiness and well-being.
