Proposed Revisions to the Lead and Copper Rule US EPA

Mar 19, 2021 & 0183;& 32;No safe level of lead exposure has been identified, and it is especially harmful to children and pregnant women. EPA established the Lead and Copper Rule LCR in 1991 to protect public health and reduce exposure to lead in drinking water. Implementation of the LCR over the past twenty-five years has resulted in major improvements in public health.Epa's Proposed Lead and Copper Rule Revisions Infographic

Resources: Standards and Properties - Copper and Copper Alloy ...

Leaded coppers are egorized as low lead alloys, or free machining alloys and high lead alloys. In the free machining alloys, the lead acts as chip breaker and lubricant making these alloys easier to machine than their non leaded counter parts. The high leaded copper alloys are used in bearing appli ions. In the bearing materials, the lead acts as a solid lubricant and the copper is the load bearing support. Lead is added to many of the copper alloys producing free …

Lead Copper Alloys - Leaded Copper Aviva Metals

Lead coppers are egorized as low lead alloys, or free-machining alloys and high lead alloys. In the free-machining alloys, the lead acts as chip breaker and lubricant which makes these alloys easier to machine than their non-leaded counter parts. High lead copper alloys are used in bearing appli ions.
