This is due to the fact that lead is practically insoluble in solid copper. Lead acts as an internal lubricant and assists in chip break up, while at the same time not affecting the structure and properties of the copper. ![]() It’s widely known that lead promotes machinability in copper alloys. ![]() This new standard will affect much of the bronze and brass products used in drinking water applications. Under the current regulation such products may contain up to 8% lead, that number is lowered to 0.25% after January 4, 2014.
