Manufacturing changes in copper alloys and their performance in the field

Compliance with the updated lead free laws for domestic water led manufacturers to change their copper alloy compositions and machining processes. As a result of these changes, new brass and bronze alloys were introduced to the commercial plumbing market in 2008. Unfortunately, some of these manufacturing changes have resulted in poor field performance when installing valves. The goal of this white paper is to present the changes in the manufacturing of copper alloys and to address dezincification susceptibility as a result of the updated lead free laws.
