Copper Nickel 70:30 / CuNi 70:30 / Alloy C71500 Fasteners

AISI 4130 Bolts

Alloy C71500 is one of the two most abundantly used copper nickel alloy with approximately 70% copper and 30% nickel by weight and other strengthening elements. Copper nickel alloy is also referred as cupronickel alloy. copper-nickelalloy UNS C71500 has medium high strength and good creep resistance at high temperatures.

This CuNi 70:30 alloy offers excellent corrosion resistance, stress corrosion cracking resistance, moderately high strength and good creep resistance at elevated temperatures. The nickel composition at 30% favors C71500 to be used in application areas of high temperatures and pressures combined with high velocity and turbulence.
