# C72200 copper-nickel-chromium, for water that erodes everything else.

A 90/10-class copper-nickel with chromium and iron additions that let it survive inlet-end turbulence and polluted seawater at velocities where standard copper-nickel wears through. Specified for naval and coastal condensers with a history of erosion failures.

## What C72200 is

C72200 is roughly 84% copper, 16% nickel, with about 0.5% chromium and 0.5% iron. The chromium strengthens the protective film so it stays put at high velocities and in turbulent inlet regions, giving C72200 erosion-corrosion resistance about double that of C70600 and better than C71500 in many tests.

It was developed for naval condensers and is now used wherever a condenser has shown repeated inlet-end erosion, or where harbor water carries sulfides that attack conventional copper-nickel.

## Standards we supply to

- ASME SB-111 / ASTM B111, condenser and heat exchanger tube
- Naval and customer specifications on request

## Chemical composition

| Element | Requirement |
| --- | --- |
| Copper | Remainder |
| Nickel | 15.0 to 18.0% |
| Chromium | 0.30 to 0.70% |
| Iron | 0.50 to 1.0% |
| Manganese | 1.0% max |
| Zinc | 1.0% max |

## Typical mechanical properties, annealed

| Property | Value |
| --- | --- |
| Tensile strength | 45,000 psi min (310 MPa) |
| Yield strength | 16,000 psi min (110 MPa) |
| Elongation in 2" | 30% min |

## Where it is used

- Naval surface ship and submarine condensers.
- Coastal power station condensers with inlet-end erosion history.
- Offshore platform seawater coolers with high flow rates.
- Any seawater exchanger where the water is polluted, sandy, or turbulent.

## Talk to us before you specify it

C72200 is a premium alloy. In clean water at moderate velocity, C70600 does the job for less. We make both and will tell you honestly which the service needs.

**What to put in your C72200 RFQ**

OD, wall, length, quantity, the governing spec, the design water velocity, and whether the service is polluted or sulfide-bearing. That last point decides whether C72200 or C71500 is the better choice.
