Application:
Lead neither solidly dissolves in copper, nor forms metal compounds with copper. Lead in copper alloy will be precipitated slowly under the action of impurities and organic acids in water. Pipes and valves made of lead brass are increasingly restricted in their use because the lead on their surfaces can enter the water when it is washed, soaked or chemically reacts with other substances in the water, causing environmental pollution and harm to human health.
