Chromium Copper C18200

UNS C18200 is chromium copper; the reviewed producer calls its product Cu-0.9Cr CC bar.

Resolve these conditions next

Is this the producer's H bar, and what ageing, diameter and acceptance requirements apply?
Obtain the full material certificate, governing specification/edition, product dimensions and test direction before adopting a property value.

For machining, take the exact grade, supplied condition and measured hardness where applicable into the tool maker’s application data. A generic material-family speed is not a substitute for an operation and tool-specific recommendation.

Sources and what they establish

Reviewed 23 October 2026. A source’s publication date and the review date are different. The scope below identifies the fields checked.

Furukawa Electric — CC bar C18200

Cu-0.9Cr bar; H condition; maker explicitly labels numerical values representative, not acceptance limits; test temperature not stated.

Source identity, a named product example and a supplied-batch certificate are different evidence. Cross-standard similarity does not approve substitution.

Corrections from the previous article

Replace the vague '380 MPa aged' with a condition-specific source route; do not turn representative conductivity into a minimum.
Remove the untraceable generic machining recommendation (40 %) and cutting-speed ranges; select machining data by actual material condition, tool and operation.
