Copper Nickel 90/10 Copper Bar

Cupronickel alloy resistant to hydrogen embrittlement.


Our cupronickel 90/10 bars offer superior welding and fabrication characteristics.

Copper Nickel 90/10 cupronickel alloy bars offer enhanced performance.


Copper Nickel 90/10 (CN102) is a cupronickel alloy. While the basis of the alloy is 90% copper and 10% nickel, small amounts of iron and manganese are introduced during the alloying process to enhance performance. Copper Nickel 90/10 is an excellent choice for applications where erosion, stress-erosion and biofouling in saltwater atmospheres are a consideration. The alloy offers an attractive combination of toughness with high ductility. Mechanical properties are retained even at cryogenic temperatures, and resistance to hydrogen embrittlement is also high.


Stock Availability

Smiths Advanced Metals stock Copper Nickel 90/10 bars in the annealed condition. Bars of grade Copper Nickel 90/10 are available in various sizes.
