| Condition · open for datasheet | Best for | Yield MPa | Tensile MPa | Elong. % | Hardness | Conductivity |
|---|---|---|---|---|---|---|
Soft annealed | Pick for maximum ductility: deep drawing, bending, tube expanding and coining before any strengthening cold work. | 85 | 260 | 40 | 50 HB | 62 % IACS |
Light annealed | Use when good formability is needed but slightly higher strength and better handling stiffness than fully soft material is wanted. | 105 | 275 | 38 | 58 HB | 61 % IACS |
H55Default Light drawn | Standard condenser/heat-exchanger tube condition: enough strength and straightness for tube-sheet rolling while still expandable and bendable. | 235 | 305 | 20 | 80 HB | 60 % IACS |
Quarter hard | Balanced strip temper for parts still needing 90° bends and moderate forming with better spring-back control than annealed. | 265 | 305 | 12 | 85 HB | 60 % IACS |
Half hard | Most common strip temper for stamped terminals, lead frames and radiator fins needing strength plus limited bending. | 300 | 335 | 8 | 95 HB | 59 % IACS |
H80This page Hard drawn | Hard-drawn tube or rod for pressure service and self-supporting runs where high strength matters more than bending ability. | 345 | 380 | 8 | 110 HB | 58 % IACS |
Full hard | Choose for flat springs, contacts and shear-formed parts where high yield strength and stress-relaxation resistance dominate over bendability. | 355 | 380 | 4 | 105 HB | 58 % IACS |
Extra hard | For high-strength flat stock where only gentle forming or flat blanking is required. | 380 | 400 | 3 | 115 HB | 57 % IACS |

Working with C19200-H80
Is C19200 easy to machine?
Gummy like pure copper (≈20 % of free-cutting brass) — use sharp positive-rake tools, high speed, generous coolant and chip breaking; harder tempers cut cleaner.
Can C19200 be welded?
Good with resistance and GTAW/GMAW using phosphor-bronze or Cu filler; soldering and brazing are excellent, but weld heat destroys cold-work strength locally.
Can C19200 be formed, bent or molded?
Excellent cold formability in O60/O50 and H01 (deep drawing, tube expanding, fin rolling); interstage anneal at 400–550 °C, and expect springback plus limited bend radii above H04.
What surface finishes work on C19200?
Not anodizable; tin, nickel, silver or gold plate for solderability/contacts, or apply benzotriazole/lacquer to control tarnish; takes a bright buffed finish.

What is the yield strength of C19200-H80?
C19200-H80 has a typical yield strength of 345 MPa (50 ksi) and a tensile strength of 380 MPa (55.1 ksi) — stronger than 73% of copper alloy grades. Strength varies by condition: see the 10 listed tempers.
Is C19200-H80 easy to machine?
Not especially — machinability is rated poor (28/100, worse than 78% of copper alloy grades). Gummy like pure copper (≈20 % of free-cutting brass) — use sharp positive-rake tools, high speed, generous coolant and chip breaking; harder tempers cut cleaner.
Can C19200-H80 be welded?
Yes — weldability is rated good (60/100). Good with resistance and GTAW/GMAW using phosphor-bronze or Cu filler; soldering and brazing are excellent, but weld heat destroys cold-work strength locally.
What surface finishes work on C19200-H80?
Not anodizable; tin, nickel, silver or gold plate for solderability/contacts, or apply benzotriazole/lacquer to control tarnish; takes a bright buffed finish.
Can C19200-H80 be formed, bent or molded?

What is the maximum service temperature of C19200-H80?
C19200-H80 is rated for continuous use to about 200°C (392 °F). Strength falls off well before that limit — check the elevated-temperature data for load-bearing parts.
What is the difference between C19200-H55 and C19200-H10?
H55 is the default condition — standard condenser/heat-exchanger tube condition: enough strength and straightness for tube-sheet rolling while still expandable and bendable. H10: highest cold-rolled strength level offered; use only for flat springs and shims with minimal forming. Yield strength is 235 MPa in H55 versus 415 MPa in H10.
