What is Cu-PHCE?

Cu-PHCE (CR022A) is an electronic-grade low-phosphorus deoxidized copper rod with tighter impurity control than standard Cu-HCP, reaching 100 % IACS conductivity and 390 W/m·K. Engineers select it for weldable and brazeable conductor parts drawn or machined from rod, with 225 MPa tensile strength, 70 MPa yield, 45 % elongation and 45 HB in the annealed condition, plus formability scored at 98 and weldability at 88. Limits are a machinability score of 25 and a service ceiling near 200 °C; Cu-HCP is the lower-cost substitute when electronic-grade purity is not required. Cu-PHCE has a density of 8.94 g/cm³ (0.323 lb/in³), heavier than 90% of copper alloy grades. It melts at 1,083°C (1,981 °F). Cu-PHCE has a yield strength of 70 MPa (10.2 ksi) and a tensile strength of 225 MPa (32.6 ksi) — weaker than 93% of copper alloy grades. Elongation at break is 45% and the elastic modulus is 117 GPa (17 Msi).

Working with Cu-PHCE

Is Cu-PHCE easy to machine?

Gummy and long-chipping — use sharp positive-rake, polished-flute tools, high speed with generous coolant; expect ~20 % of AISI 1212 rate and add free-machining alternatives (C14500/C36000) if volume machining dominates.

Can Cu-PHCE be welded?

Excellent for GTAW/GMAW, resistance and laser welding: phosphorus deoxidation removes hydrogen-embrittlement risk of ETP copper, but preheat 200–500 °C on thick sections because of the very high thermal conductivity.

Can Cu-PHCE be formed, bent or molded?

Outstanding cold formability in the annealed condition (deep drawing, upsetting, heavy bending); anneal 400–600 °C between heavy passes and expect rapid work-hardening in the hard tempers.

What surface finishes work on Cu-PHCE?

Not anodisable; takes tin, silver, nickel and gold plating readily, mirror-polishes well, and needs BTA/lacquer or plating to prevent oxide and sulphide tarnish in service.

Cu-PHCE — frequently asked

What is Cu-PHCE used for?

Cu-PHCE is typically used for electronic connector rod stock, brazed electronic housings and precision conductor parts. In short: electronic-grade deoxidized copper; 100 % IACS conductivity; top-rated cold formability.

What is the yield strength of Cu-PHCE?

Cu-PHCE has a typical yield strength of 70 MPa (10.2 ksi) and a tensile strength of 225 MPa (32.6 ksi) — weaker than 93% of copper alloy grades. Strength varies by condition: see the 6 listed tempers.

Is Cu-PHCE easy to machine?

Not especially — machinability is rated poor (25/100, worse than 86% of copper alloy grades). Gummy and long-chipping — use sharp positive-rake, polished-flute tools, high speed with generous coolant; expect ~20 % of AISI 1212 rate and add free-machining alternatives (C14500/C36000) if volume machining dominates.

Can Cu-PHCE be welded?

Yes — weldability is rated excellent (88/100). Excellent for GTAW/GMAW, resistance and laser welding: phosphorus deoxidation removes hydrogen-embrittlement risk of ETP copper, but preheat 200–500 °C on thick sections because of the very high thermal conductivity.

What surface finishes work on Cu-PHCE?

Not anodisable; takes tin, silver, nickel and gold plating readily, mirror-polishes well, and needs BTA/lacquer or plating to prevent oxide and sulphide tarnish in service.

Can Cu-PHCE be formed, bent or molded?

Outstanding cold formability in the annealed condition (deep drawing, upsetting, heavy bending); anneal 400–600 °C between heavy passes and expect rapid work-hardening in the hard tempers.

What is the maximum service temperature of Cu-PHCE?

Cu-PHCE is rated for continuous use to about 200°C (392 °F). Strength falls off well before that limit — check the elevated-temperature data for load-bearing parts.

What is the difference between Cu-PHCE-R220 and Cu-PHCE-H110?

R220 is the default condition — most stocked condition — maximum conductivity and ductility for bending, upsetting, brazing and welded conductor work. H110: heavily drawn small sections where tensile strength and springback matter more than bendability. Yield strength is 70 MPa in R220 versus 340 MPa in H110.
