ABSTRACT:
Tubes for water and/or hot-water supply use, which are made of Cu-base-alloys essentially containing Mg from 0.05 to 2.8 wt % and the balance Cu and inevitable impurities, have been found to have conspicuously low dissolution rates of undesirable ions, especially Cu ions and other ions, even in stagnant water and/or at elevated temperature. The alloys are desirably further contain up to 1.0% Ca to further restrain dissolution of Cu ions.
