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.
