Compare all 6 conditionsHide
| Condition · open for datasheet | Best for | Yield MPa | Tensile MPa | Elong. % | Hardness | Conductivity |
|---|---|---|---|---|---|---|
Solution heat treated | Softest, most formable condition — pick when parts are deep-formed or heavily machined before age hardening. | 160 | 330 | 28 | 90 HB | 28 % IACS |
Solution heat treated and cold worked, half hard | Intermediate stiffness/strength for parts that still need some bending before aging. | 370 | 450 | 12 | 130 HB | 30 % IACS |
Solution heat treated and cold worked, full hard | Cold-drawn rod/strip used where the part will be aged after machining, or where moderate strength without heat treatment is enough. | 480 | 540 | 8 | 160 HB | 32 % IACS |
TF00Default Solution heat treated and precipitation hardened | Standard stocked rod condition: near-isotropic aged properties with high conductivity, best for machined electrode and contact parts. | 550 | 690 | 15 | 22 HRC | 50 % IACS |
TD02 and precipitation hardened | Compromise between the ductility of TF00 and the peak strength of TH04 for formed-then-aged components. | 620 | 725 | 12 | 24 HRC | 50 % IACS |
TD04 and precipitation hardened | Peak-strength condition for small-diameter rod, springs and highly loaded contacts that still need ~50 % IACS. | 690 | 760 | 9 | 28 HRC | 52 % IACS |
What is C17465?
C17465 is a leaded, nickel-bearing beryllium copper in the wrought lightly alloyed copper family (C10000–C19999), aged to 550 MPa yield, 690 MPa tensile and 195 HB (22 HRC) while keeping 50 % IACS and 215 W/m·K. The lead addition lifts machinability to a rating of 65, so it is used for turned connectors, precision bushings and mould components that need beryllium-copper strength and conductivity on high-volume screw-machine work. Fusion weldability is poor (rating 25) and formability is limited (rating 25), with a 300 °C service ceiling; unleaded C17510 or C17200 are the alternatives when welding or deep forming is required. C17465 has a density of 8.83 g/cm³ (0.319 lb/in³), heavier than 65% of copper alloy grades. It melts at 1,000°C (1,832 °F). C17465 has a yield strength of 550 MPa (79.8 ksi) and a tensile strength of 690 MPa (100 ksi) — stronger than 92% of copper alloy grades. Elongation at break is 15% and the elastic modulus is 138 GPa (20 Msi).

Working with C17465
Is C17465 easy to machine?
Lead addition gives short chips and good surface finish — turn dry or with flood coolant at BeCu speeds, and capture all dust/fines under local exhaust because beryllium particulate is hazardous.
Can C17465 be welded?
Fusion welding is unreliable (lead-induced hot cracking); use resistance or electron-beam joining on unleaded transition pieces, or mechanical/brazed joints.
Can C17465 be formed, bent or molded?
Form only in TB00/TD02; aged tempers have limited bend ductility — age after forming (typically ~480 °C, 2–3 h) with allowance for slight growth.

What surface finishes work on C17465?
Not anodizable; electroless nickel, silver or tin plating are standard, and the aged alloy polishes to a bright, wear-resistant surface.

C17465 — frequently asked
What is C17465 used for?
C17465 is typically used for connectors, precision bushings and molds. In short: free-machining beryllium copper; 50 % IACS at 550 MPa; 300 °C service ceiling.
What is the yield strength of C17465?
C17465 has a typical yield strength of 550 MPa (79.8 ksi) and a tensile strength of 690 MPa (100 ksi) — stronger than 92% of copper alloy grades. Strength varies by condition: see the 6 listed tempers.
Is C17465 easy to machine?
Reasonably — machinability is rated good (65/100, better than 76% of copper alloy grades). Lead addition gives short chips and good surface finish — turn dry or with flood coolant at BeCu speeds, and capture all dust/fines under local exhaust because beryllium particulate is hazardous.
Can C17465 be welded?
Not readily — weldability is rated poor (25/100). Fusion welding is unreliable (lead-induced hot cracking); use resistance or electron-beam joining on unleaded transition pieces, or mechanical/brazed joints.
What surface finishes work on C17465?
Not anodizable; electroless nickel, silver or tin plating are standard, and the aged alloy polishes to a bright, wear-resistant surface.
Can C17465 be formed, bent or molded?
Form only in TB00/TD02; aged tempers have limited bend ductility — age after forming (typically ~480 °C, 2–3 h) with allowance for slight growth.
What is the maximum service temperature of C17465?
C17465 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 C17465-TF00 and C17465-TB00?
TF00 is the default condition — standard stocked rod condition: near-isotropic aged properties with high conductivity, best for machined electrode and contact parts. TB00: softest, most formable condition — pick when parts are deep-formed or heavily machined before age hardening. Yield strength is 550 MPa in TF00 versus 160 MPa in TB00.
