Copper Nickel 70/30 Fasteners

CN  70 30 Fasteners are made up of 70% copper and 30% nickel, with a small amount of manganese and iron added to help strengthen the fastener and improve its resistance to marine bio-fouling. These fasteners are incredibly durable thanks to the combined beneficial properties of copper and nickel. Beyond their excellent performance in salty environments, Copper Nickel 70 30 Fasteners have excellent thermal conductivity, which makes them very compatible with a wide range of high-temperature applications ranging from steam boilers to super heaters. Not only are they resistant to corrosion, but they also offer superior corrosion protection against hydrogen embrittlement when used with stainless steel substrates.

Copper Nickel 70 30 Fasteners are a versatile choice with numerous uses in various industries. Copper Nickel alloys offer greater strength and resistance to corrosion than other fastener materials and stand up well to exposure to salt water, moisture, and a range of temperatures. Due to their robust mechanical properties, Copper Nickel 70 30 Fasteners are commonly used on boats, submarines, and ships to join underwater steel plates where marine grade stainless steel may not be suitable because of lower cost. These fasteners can also be found in chemical plants for their excellent resistance against caustic chemicals and sulfides that are often encountered there. Government regulations specify that these alloys must be used for some applications due to their low magnetic permeability, which makes them ideal for sensitive electronic mechanisms.
