Nibron®  (UNS C72400/2.1504) Fasteners

Nibron® Is one of the highest strength copper alloys available with good levels of ductility.  it is resistant to hydrogen embrittlement, stress corrosion cracking and both pitting and crevice attack. The alloy retains a useful level of strength up to temperatures of around 250oC and is not prone to embrittlement at sub-zero temperatures.  It offers high wear resistance and exhibits good anti-galling characteristics in many applications.

Although it is harder than normal bronzes, Nibron® is readily machinable and is used in a wide variety of applications.  These include high strength bolting and critical subsea components employed in aggressive offshore environments, hydraulic components, landing gear bushes and many other critical engineering components.
