Compare all 8 conditionsHide
| Condition · open for datasheet | Best for | Yield MPa | Tensile MPa | Elong. % | Hardness | Conductivity |
|---|---|---|---|---|---|---|
Soft annealed | Pick for maximum conductivity, deep cold forming, riveting or staking of machined parts. | 75 | 225 | 50 | 45 HB | 95 % IACS |
As hot rolled | Large-diameter extruded rod/bar sold before drawing; used where sections are turned heavily anyway. | 85 | 230 | 45 | 50 HB | 94 % IACS |
Annealed to 0.050 mm grain size | Grain-size-controlled anneal for strip/wire that will be deep drawn or heavily formed after supply. | 85 | 235 | 48 | 48 HB | 95 % IACS |
1/8 hard | Light draw for straightness and size tolerance while keeping most of the annealed ductility. | 165 | 250 | 35 | 66 HB | 94 % IACS |
Quarter hard | Compromise temper when parts must be machined and then bent or crimped. | 215 | 275 | 25 | 68 HB | 94 % IACS |
Half hard | Standard temper for screw-machine parts that still need moderate staking, swaging or bending. | 250 | 300 | 20 | 78 HB | 93 % IACS |

What is C14510?
C14510 is a tellurium copper from the C14500 free-machining family, deoxidized with a controlled low phosphorus addition that improves cold formability while holding a machinability rating of 88. It is used as rod, bar and wire in O60, OS050, M20 and H00–H06 tempers for cold-headed and screw-machined electrical parts, with 93% IACS, 355 W/m·K, 305 MPa yield, 340 MPa tensile and 12% elongation in the default condition. Tellurium rules out fusion welding and service is limited to about 180 °C; C14520 is the closer choice when brazing and resistance welding dominate. C14510 has a density of 8.94 g/cm³ (0.323 lb/in³), heavier than 90% of copper alloy grades. It melts at 1,051°C (1,924 °F). C14510 has a yield strength of 305 MPa (44.2 ksi) and a tensile strength of 340 MPa (49.3 ksi) — stronger than 62% of copper alloy grades. Elongation at break is 12% and the elastic modulus is 117 GPa (17 Msi).

Working with C14510
Is C14510 easy to machine?
Runs like free-cutting brass at high speed with sharp positive-rake tools and light feeds; expect short broken chips and ~85 % of C36000 productivity.
Can C14510 be welded?
Avoid fusion welding — tellurium causes hot short cracking; join by soldering, silver brazing or resistance/friction methods.
Can C14510 be formed, bent or molded?
Half-hard and softer tempers bend and stake well thanks to the low-P chemistry; H04/H06 tolerate only light forming, anneal 400–600 °C if severe work is needed.
C14510 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 |
|---|---|---|
| Tefree-machining chip-breaking phase (Cu₂Te) | 0.3 – 0.7 | 0.5 |
| Plow, controlled deoxidant — keeps conductivity high | 0 – 0.02 | 0.01 |

What surface finishes work on C14510?
Solders and silver-brazes readily, plates well with Ni/Ag/Sn after acid activation; not anodisable and will tarnish unless lacquered or plated.

C14510 — frequently asked
What is C14510 used for?
C14510 is typically used for connectors and terminals, switch and relay parts and cold-headed fasteners. In short: free-machining copper, 93% IACS; better cold heading than C14500; high conductivity, high machinability.
What is the yield strength of C14510?
C14510 has a typical yield strength of 305 MPa (44.2 ksi) and a tensile strength of 340 MPa (49.3 ksi) — stronger than 62% of copper alloy grades. Strength varies by condition: see the 8 listed tempers.
Is C14510 easy to machine?
Yes — machinability is rated excellent (88/100, better than 96% of copper alloy grades). Runs like free-cutting brass at high speed with sharp positive-rake tools and light feeds; expect short broken chips and ~85 % of C36000 productivity.
Can C14510 be welded?
Not readily — weldability is rated poor (25/100). Avoid fusion welding — tellurium causes hot short cracking; join by soldering, silver brazing or resistance/friction methods.
What surface finishes work on C14510?
