| Condition · open for datasheet | Best for | Yield MPa | Tensile MPa | Elong. % | Hardness | Conductivity |
|---|---|---|---|---|---|---|
Soft annealed | Fully annealed coil tube and sheet for maximum ductility — ACR coils, flare fittings, deep drawing and spinning. | 70 | 225 | 45 | 42 HB | 85 % IACS |
As hot rolled | Mill-finish hot-worked plate, bar and busbar-size sections supplied without a final cold pass or anneal. | 75 | 220 | 40 | 45 HB | 85 % IACS |
Light annealed | Soft but fine-grained tube/strip for tight bending with a better surface and slightly higher strength than full anneal. | 90 | 235 | 42 | 48 HB | 85 % IACS |
H00This page 1/8 hard | Barely work-hardened flat product for deep forming that still needs some spring and flatness. | 170 | 250 | 30 | 65 HB | 85 % IACS |
Light drawn | Lightly cold-drawn tube that still bends on a machine but is stiffer and straighter than annealed coil. | 190 | 255 | 28 | 70 HB | 85 % IACS |
Quarter hard | Quarter-hard strip for moderate bending and stamping of gaskets, washers and roofing sheet. | 205 | 265 | 25 | 75 HB | 85 % IACS |

Half hard | Half-hard plate and strip: the usual choice for flat gaskets, busbar and fabricated panels needing stiffness plus some bendability. | 250 | 295 | 14 | 88 HB | 84 % IACS |
Full hard | Hard-rolled flat and drawn rod product for flat springs, contacts and parts needing stiffness and wear resistance. | 280 | 320 | 7 | 95 HB | 84 % IACS |

Working with TP2-H00
Is TP2 easy to machine?
Gummy and low-rated (~20 % of AISI 1212): use sharp positive-rake tools, high speed, generous cutting fluid and chip breaking; choose C14500 or free-cutting brass for screw-machine work.
Can TP2 be welded?
Phosphorus deoxidation means no hydrogen embrittlement — GTAW/GMAW with ERCu filler, preheat 200–400 °C for sections above ~3 mm; brazing with BCuP filler needs no flux on copper-to-copper joints.
Can TP2 be formed, bent or molded?
Excellent cold formability in O60 (bend, flare, expand, deep draw); intermediate anneals at 400–600 °C restore ductility after ~50 % reduction; hot working 750–950 °C.
What surface finishes work on TP2?
Polishes to a bright finish and takes tin, nickel or silver plating well; not anodizable — protect with lacquer or accept natural patina, and avoid ammonia-based cleaners.

TP2-H00 — frequently asked
What is TP2-H00 used for?
TP2-H00 is typically used for air-conditioning tube, plumbing tube, heat exchangers and brazed fittings. In short: standard brazeable copper tube; no hydrogen embrittlement; lower conductivity than ETP.
What is the yield strength of TP2-H00?
TP2-H00 has a typical yield strength of 170 MPa (24.7 ksi) and a tensile strength of 250 MPa (36.3 ksi) — weaker than 62% of copper alloy grades. Strength varies by condition: see the 12 listed tempers.
Is TP2-H00 easy to machine?
Not especially — machinability is rated poor (25/100, worse than 86% of copper alloy grades). Gummy and low-rated (~20 % of AISI 1212): use sharp positive-rake tools, high speed, generous cutting fluid and chip breaking; choose C14500 or free-cutting brass for screw-machine work.
Can TP2-H00 be welded?
Yes — weldability is rated excellent (85/100). Phosphorus deoxidation means no hydrogen embrittlement — GTAW/GMAW with ERCu filler, preheat 200–400 °C for sections above ~3 mm; brazing with BCuP filler needs no flux on copper-to-copper joints.
What surface finishes work on TP2-H00?
Polishes to a bright finish and takes tin, nickel or silver plating well; not anodizable — protect with lacquer or accept natural patina, and avoid ammonia-based cleaners.
Can TP2-H00 be formed, bent or molded?
Excellent cold formability in O60 (bend, flare, expand, deep draw); intermediate anneals at 400–600 °C restore ductility after ~50 % reduction; hot working 750–950 °C.
What is the maximum service temperature of TP2-H00?
TP2-H00 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 TP2-H58 and TP2-O60?
H58 is the default condition — the default stocked condition: cold-drawn straight lengths of TP2 water/gas/medical-gas tube — rigid, pressure-rated, brazed rather than bent. O60: fully annealed coil tube and sheet for maximum ductility — ACR coils, flare fittings, deep drawing and spinning. Yield strength is 250 MPa in H58 versus 70 MPa in O60.
