Cu-DHP vs CuBe2
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.
CuBe2
CW101C
THE highest-strength copper alloy — UTS up to 1400 MPa (200 ksi), approaching steel strength with copper's conductivity (22% IACS aged). Age-hardenable: solution treat 780-800°C, age 315-340°C → HRC 38-45. Non-sparking, non-magnetic. Trade names: Alloy 25 (Materion), BeCu25 (NGK). CAUTION: Be dust is carcinogenic — machining requires extraction. Used for non-sparking tools, mold inserts, springs, connectors, and resistance welding electrodes.
