What is C41500?
C41500 is a tin brass strip and tube alloy in the wrought brass series, combining good cold formability with the corrosion resistance the tin addition provides. It is drawn and roll-formed into flexible tube and electrical hardware: the default condition gives 400 MPa yield, 455 MPa tensile, 12% elongation, 72 HRB, 28% IACS conductivity, a 150 °C maximum service temperature and a formability score of 55. Machinability is low at 32 (about 30% of free-cutting brass) and fusion welding is only fair, so plan on soldering, brazing or resistance welding. C41300 is the nearest alternative for flat stamped parts. C41500 has a density of 8.78 g/cm³ (0.317 lb/in³), heavier than 53% of copper alloy grades. It melts at 955°C (1,751 °F). C41500 has a yield strength of 400 MPa (58 ksi) and a tensile strength of 455 MPa (66 ksi) — stronger than 80% of copper alloy grades. Elongation at break is 12% and the elastic modulus is 110 GPa (16 Msi).

Working with C41500
Is C41500 easy to machine?
Machinability about 30 % of free-cutting brass — use sharp positive-rake tools, good chip breaking and flood coolant; chips are stringy in soft tempers.
Can C41500 be welded?
Resistance and brazing/soldering are excellent; fusion welding (GTAW) is only fair due to zinc fume and porosity — use low heat input and phosphor-bronze filler.
Can C41500 be formed, bent or molded?
Excellent cold forming in OS tempers (deep draw, roll form, convolute); interanneal ~450–600 °C and stress-relieve formed parts (~250 °C) to prevent ammonia SCC.
C41500 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 |
|---|---|---|
| Cuincludes Ag | 89 – 93 | 91 |

What surface finishes work on C41500?
Takes bright polishing, tin, nickel and silver plating readily; not anodizable — protect with lacquer or benzotriazole tarnish inhibitor.

C41500 — frequently asked
What is C41500 used for?
C41500 is typically used for flexible hose/tube, electrical hardware and corrugated tubing. In short: formable tin brass tube; convolutes without cracking; low machinability rating.
What is the yield strength of C41500?
C41500 has a typical yield strength of 400 MPa (58 ksi) and a tensile strength of 455 MPa (66 ksi) — stronger than 80% of copper alloy grades. Strength varies by condition: see the 9 listed tempers.
Is C41500 easy to machine?
Not especially — machinability is rated poor (32/100, worse than 57% of copper alloy grades). Machinability about 30 % of free-cutting brass — use sharp positive-rake tools, good chip breaking and flood coolant; chips are stringy in soft tempers.
Can C41500 be welded?
With care — weldability is rated fair (45/100). Resistance and brazing/soldering are excellent; fusion welding (GTAW) is only fair due to zinc fume and porosity — use low heat input and phosphor-bronze filler.
What surface finishes work on C41500?

What is the maximum service temperature of C41500?
C41500 is rated for continuous use to about 150°C (302 °F). Strength falls off well before that limit — check the elevated-temperature data for load-bearing parts.
What is the difference between C41500-H02 and C41500-OS035?
H02 is the default condition — most commonly stocked strip temper: balanced strength and forming for terminals, hose and hardware. OS035: softest commercial anneal for deep drawing and severe bending of tube and cup shapes. Yield strength is 400 MPa in H02 versus 110 MPa in OS035.
