C18150 CuCrZr/CuCr1Zr CHROMIUM ZIRCONIUM COPPER SHEET
Short Description:
The chemical composition of C18150 is 1% chromium, 98.85% copper, and 0.15% zirconium. The addition of Zirconium to chromium copper improves creep resistance at high operating temperatures and reduces sticking of electrodes to the work during spot welding of galvanized or coated materials. The physical copper properties of C18150 include a density of 8.89 grams per cubic centimeter.

TYPICAL USES OF CHROMIUM ZIRCONIUM
STRESS RELAXATION
Chromium zirconium is a unique copper alloy that’s able to decrease stress under constant strain. It’s typically used with steel bolts in turbine casting, which must be straightened and typed.
MACHINING
Machining includes a variety of processes in which a raw piece of material is cut into a desired final shape and size by a controlled material-removal process. The machinability rating of C18150 is 30% which is moderate. The use of a cutting tool with a chip breaker is recommended.
