Cu-DHP vs CuZn39Pb3: 0% composition overlap. Significantly different materials serving different application areas.
Cu-DHP vs CuZn39Pb3
Side-by-side chemical composition and mechanical property comparison.
Overview
Cu-DHP
CW024A
Phosphorus-deoxidized copper (DHP = Deoxidized High Phosphorus, 0.015-0.040% P). THE material for copper plumbing tubes worldwide (EN 1057). P prevents hydrogen embrittlement during brazing/welding — essential for plumbing/HVAC joints. Slightly lower electrical conductivity than Cu-ETP (85% IACS vs 101%) due to P content. UNS C12200. Used for plumbing tubes, heating systems, solar thermal, refrigeration tubes, and architectural roofing.
CuZn39Pb3
2.0401
The most widely used free-cutting brass (machinability index 100%). Excellent for high-speed automatic lathe work. Used for turned parts, faucets, valves, fittings, screws, nuts, electrical connectors, and watch components. Also known as MS58.
