What is C60800?
C60800 is a low-alloy aluminum bronze with about 5% Al in the C50000–C69999 wrought bronze family, supplied mainly as tube. It is chosen for condenser and heat-exchanger duty where corrosion resistance and formability matter more than strength: 186 MPa yield, 415 MPa tensile, 55% elongation, 100 HB (55 HRB), 82 W/m·K thermal conductivity and 17% IACS, with a formability score of 82. The single-phase structure is gummy to machine, the alumina film must be removed before joining, and soldering or oxyacetylene welding is not suitable. C61000 is the nearest alternative when higher strength is needed. C60800 has a density of 8.17 g/cm³ (0.295 lb/in³), lighter than 86% of copper alloy grades. It melts at 1,035°C (1,895 °F). C60800 has a yield strength of 186 MPa (27 ksi) and a tensile strength of 415 MPa (60.2 ksi) — weaker than 58% of copper alloy grades. Elongation at break is 55% and the elastic modulus is 117 GPa (17 Msi).

Working with C60800
Is C60800 easy to machine?
Gummy, tough alpha bronze (≈20 % of free-cutting brass): use sharp positive-rake carbide tooling, slow feeds, generous coolant and expect long stringy chips.
Can C60800 be welded?
GTAW/GMAW with aluminum-bronze filler (ERCuAl-A2) works well under gas shielding; the tenacious alumina film must be removed, and oxyacetylene welding or soldering is not recommended.
Can C60800 be formed, bent or molded?
Annealed tube cold-forms, bends and expands readily; interanneal near 600–700 °C for heavy cold work and hot-work around 700–850 °C.
C60800 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 |
|---|---|---|
| Al | 5 – 6.5 | 5.7 |
| Asinhibits dealuminification | 0.02 – 0.35 | 0.06 |

What surface finishes work on C60800?
Not anodizable; pickle in dilute sulfuric/nitric to strip alumina film, then polish, tin/nickel plate for solderability, or leave to develop a protective oxide in service.
Surface treatments FabDigit runs on copper alloy parts — pick them in the quote configurator or call them out on the drawing. Each links to its datasheet in the surface-finish library (thickness, specs, call-out, material verdicts).
How much does C60800 cost?
C60800 is a high-cost copper alloy ($$$$), pricier than about 78% of the materials FabDigit quotes. Part price depends far more on geometry, tolerance and quantity than on the raw stock — upload a CAD file for a live quote.
C60800 — frequently asked
What is C60800 used for?
C60800 is typically used for condenser tubing, heat exchanger tubes and marine piping. In short: tube-grade aluminum bronze; very high formability; poor machinability.
What is the yield strength of C60800?
C60800 has a typical yield strength of 186 MPa (27 ksi) and a tensile strength of 415 MPa (60.2 ksi) — weaker than 58% of copper alloy grades. Strength varies by condition: see the 4 listed tempers.
Is C60800 easy to machine?
Not especially — machinability is rated poor (28/100, worse than 78% of copper alloy grades). Gummy, tough alpha bronze (≈20 % of free-cutting brass): use sharp positive-rake carbide tooling, slow feeds, generous coolant and expect long stringy chips.
Can C60800 be welded?
Yes — weldability is rated very good (70/100). GTAW/GMAW with aluminum-bronze filler (ERCuAl-A2) works well under gas shielding; the tenacious alumina film must be removed, and oxyacetylene welding or soldering is not recommended.
What surface finishes work on C60800?

Annealed tube cold-forms, bends and expands readily; interanneal near 600–700 °C for heavy cold work and hot-work around 700–850 °C.
What is the maximum service temperature of C60800?
C60800 is rated for continuous use to about 250°C (482 °F). Strength falls off well before that limit — check the elevated-temperature data for load-bearing parts.
What is the difference between C60800-O61 and C60800-H80?
O61 is the default condition — standard condition for ASTM B111 condenser/heat-exchanger tube — maximum ductility for expanding and rolling into tubesheets. H80: rarely stocked; used where higher strength and stiffness of the tube wall matter more than expandability. Yield strength is 186 MPa in O61 versus 400 MPa in H80.
How much does C60800 cost?
C60800 is a high-cost copper alloy ($$$$), pricier than about 78% of the materials FabDigit quotes. Part price depends far more on geometry, tolerance and quantity than on the raw stock — upload a CAD file for a live quote.
