C18150 size 15x15x200mm rectangle bar Chromium Zirconium Copper
Product brief introduction
CuCr1Zr – UNS.C18150 Chromium Zirconium Copper C18150 is an excellent and unique copper
alloy with high electrical conductivity, hardness, and ductility,
moderate strength, and excellent resistance to softening at
elevated temperatures. The addition of 0.1% zirconium (Zr) and 1.0%
chromium (Cr) to copper results in a heat treatable alloy which may
be solution treated and subsequently aged to produce these
desirable properties. Rod is usually supplied from the mill in the
fully aged and drawn condition so no further heat treatment is
required by the fabricator. The softening temperature of properly
heat treated C18150 rod exceeds 500°C as compared to unalloyed pure
copper which softens at 200°C, and silver bearing coppers which
soften at 350°C.
Furthermore, many evidences shows that C18150 can provide less
sticking and resisting deformation longer than its C18200
counterpart in some specific situatons.
