Standard wrought copper plumbing fittings and pure copper components are manufactured from high-purity copper alloys (typically containing roughly 99.9% pure copper metal) to ensure optimal malleability, corrosion resistance, and solderability. However, certain specialized cast bronze or brass fittings—which are also frequently used alongside copper pipe systems—contain multi-metal alloy compositions incorporating copper combined with zinc, tin, or silicon to achieve specific structural casting strengths.
