Cu-DHP vs CuCr1Zr (CW106C)
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.
CuCr1Zr (CW106C)
CW106C
Chromium-zirconium copper alloy, precipitation hardened. High electrical/thermal conductivity (~80% IACS) with significantly higher strength and hardness than pure copper. Age-hardened: Rm 440–540 MPa, Rp0.2 380–480 MPa, HB 130–170. Softening temperature ~500°C. UNS C18150, EN CW106C. Applications: resistance welding electrodes and caps, continuous casting molds, circuit breaker contacts, lead frames, MIG welding tips. THE standard electrode material.
