Working with C14200
Is C14200 easy to machine?
Gummy like all high-purity copper (≈20% of AISI 1212) — use sharp positive-rake tools, high speed, generous coolant; cold-worked tempers chip better than annealed.
Can C14200 be welded?
P-deoxidized and oxygen-free of hydrogen embrittlement risk; GTAW/GMAW with ERCu or Si-bronze filler and preheat on heavy sections; brazing and soldering are excellent, and As does not impair joints.
Can C14200 be formed, bent or molded?
Excellent cold formability in OS tempers (U-bending, tube expansion, roll-in to tubesheets); interanneal at 400–600 °C after ~50% reduction — arsenic raises the recrystallisation temperature versus DHP copper.
C14200 chemical composition (wt %)
Limits by weight percent from the governing specification, written the way the spec states them — a single maximum for impurities, a range for alloying elements, and the base element as balance. Nominal is the typical mid-range value.
| Element | Spec limit (wt %) | Nominal |
|---|---|---|
| Asarsenic addition for corrosion & elevated-temperature strength | 0.15 – 0.5 | 0.3 |
| Presidual deoxidizing phosphorus | 0.02 – 0.04 | 0.03 |
| CuCu + Ag, remainder; per UNS C14200 / ASTM B111 | ≥ 99.4 (balance) |
What surface finishes work on C14200?
Not anodizable; specify pickling/bright dip, mechanical polishing, tin or nickel plating, or benzotriazole passivation to slow tarnishing.

C14200 — frequently asked
What is C14200 used for?
C14200 is typically used for condenser and heat exchanger tube, boiler tube and marine tubing. In short: arsenical condenser-tube copper; strength retained to 300 °C; excellent tube formability.
What is the yield strength of C14200?
C14200 has a typical yield strength of 69 MPa (10 ksi) and a tensile strength of 225 MPa (32.6 ksi) — weaker than 96% of copper alloy grades. Strength varies by condition: see the 9 listed tempers.
Is C14200 easy to machine?
Not especially — machinability is rated poor (30/100, worse than 67% of copper alloy grades). Gummy like all high-purity copper (≈20% of AISI 1212) — use sharp positive-rake tools, high speed, generous coolant; cold-worked tempers chip better than annealed.
Can C14200 be welded?
Yes — weldability is rated very good (70/100). P-deoxidized and oxygen-free of hydrogen embrittlement risk; GTAW/GMAW with ERCu or Si-bronze filler and preheat on heavy sections; brazing and soldering are excellent, and As does not impair joints.

What is the maximum service temperature of C14200?
C14200 is rated for continuous use to about 300°C (572 °F). Strength falls off well before that limit — check the elevated-temperature data for load-bearing parts.
What is the difference between C14200-OS050 and C14200-H80?
OS050 is the default condition — standard soft condenser/heat-exchanger tube temper — maximum ductility for tube rolling and U-bending. H80: fully hard-drawn tube for maximum pressure rating and rigidity where no severe bending is required. Yield strength is 69 MPa in OS050 versus 345 MPa in H80.
