Cu-DHP vs CuFe2P: 9% composition overlap. Significantly different materials serving different application areas.
Cu-DHP vs CuFe2P
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.
CuFe2P
CW107C
Precipitation-hardened copper-iron alloy — THE semiconductor leadframe material since 1964. Fe precipitates give UTS up to 580 MPa while maintaining 60-65% IACS electrical conductivity. Resists softening to 350°C (critical for IC packaging). Also used for automotive connectors, pin grid arrays (PGA), and terminals. Trade names: Wieland K65, Aurubis PNA212.
