Description

CuNi2 NC005 2.0802 Cupronickel Wire Perfect Solution For Stress Corrosion Cracking And Pitting Resistance

CuNi2, a copper-nickel alloy containing approximately 2% nickel, is a versatile material known for its combination of good corrosion resistance, moderate mechanical strength, and excellent thermal and electrical conductivity. This alloy is particularly suited for applications requiring durability, ease of fabrication, and stable performance under various environmental conditions.

With a composition of 98% copper and 2% nickel, CuNi2 retains most of copper's desirable properties while benefiting from the addition of nickel. The nickel content improves its resistance to oxidation and corrosion, particularly in moist or mildly aggressive environments.
