What is C14180?
C14180 is a high-purity oxygen-free copper filler metal for furnace brazing of steel and copper in a reducing atmosphere or vacuum, supplied as annealed or hard-drawn wire, stamped preforms, powder and paste. It is chosen because it wets clean steel without flux and leaves a ductile joint: 210 MPa tensile, 60 MPa yield, 35 % elongation, HB 42, 98 % IACS and 385 W/m·K as brazed. Joints need close fits of 0.00-0.05 mm and a controlled furnace run at 1093-1149 °C, and service is limited to roughly 400 °C. C14181 is the choice when vacuum-melt purity is required. C14180 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). C14180 has a yield strength of 60 MPa (8.7 ksi) and a tensile strength of 210 MPa (30.5 ksi) — weaker than 100% of copper alloy grades. Elongation at break is 35% and the elastic modulus is 115 GPa (16.7 Msi).

Working with C14180
Is C14180 easy to machine?
Pure copper is gummy — use sharp, high-rake, polished-flute tools, high speed and generous coolant; filler is normally used as-supplied, not machined.
Can C14180 be welded?
The filler itself is braze-applied, not welded; base metals must be clean, oxide-free and brazed at 1093–1149 °C in H₂/dissociated-ammonia/endothermic atmosphere (dew point ≤ −35 °C) or vacuum, with joint clearance 0.00–0.05 mm.
Can C14180 be formed, bent or molded?
Annealed wire and foil coil, bend and stamp easily into rings and shims; hard-drawn wire should be re-annealed before tight-radius ring forming.
C14180 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 |
|---|---|---|
| Presidual deoxidiser | ≤ 0.08 | 0.02 |
| Pb | ≤ 0.02 | |
| Altrace, avoids poor wetting | ≤ 0.01 | |

What surface finishes work on C14180?
Joints come out bright and flux-free from a good furnace run; copper fillets tarnish in air and can be tin, nickel or silver plated, or passivated with benzotriazole.

C14180 — frequently asked
What is C14180 used for?
C14180 is typically used for furnace-brazed steel assemblies, automotive radiators/heat exchangers, sprockets and gears and valve and hardware brazing. In short: flux-free furnace braze filler; copper filler for steel; 98 % IACS joint.
What is the yield strength of C14180?
C14180 has a typical yield strength of 60 MPa (8.7 ksi) and a tensile strength of 210 MPa (30.5 ksi) — weaker than 100% of copper alloy grades.
Is C14180 easy to machine?
Not especially — machinability is rated poor (25/100, worse than 86% of copper alloy grades). Pure copper is gummy — use sharp, high-rake, polished-flute tools, high speed and generous coolant; filler is normally used as-supplied, not machined.
Can C14180 be welded?
With care — weldability is rated fair (45/100). The filler itself is braze-applied, not welded; base metals must be clean, oxide-free and brazed at 1093–1149 °C in H₂/dissociated-ammonia/endothermic atmosphere (dew point ≤ −35 °C) or vacuum, with joint clearance 0.00–0.05 mm.

What is the maximum service temperature of C14180?
C14180 is rated for continuous use to about 400°C (752 °F). Strength falls off well before that limit — check the elevated-temperature data for load-bearing parts.
