Ni-Span-C Alloy 902 N09902 Nickel Alloy Seamless Tube For Bourdon Tubular

Product Specification

Ni-Span-C Alloy 902 is a well-known nickel-iron alloy with a controllable thermoplastic coefficient which is the alloy’s outstanding characteristic. 

It is precipitation hardenable and could be processed to have a constant modulus of elasticity at temperatures from -50 to 150°F(-45-65°C).

NI-SPAN-C nickel-iron-chromium alloy 902 is designated UNS N09902. The alloy is produced in the form of round bar, strip, wire, thin gauge strip, round tube. Special Bourdon tubular is available from convertors.

Ni-Span-C Alloy 902 has a reasonably high degree of  corrosion resisitance in mild industy atmospheres but will rust in moist air.

Spec

• SAE AMS 5221 - Strip, solution annealed
• SAE AMS 5223 - Strip, 10% cold rolled
• SAE AMS 5225 - Strip, 50% cold rolled

Key Features

• Outstanding controllable thermoelastic coefficient characteristics
• Can be processed to have constant modulus of elasticity from from -45 to +65°C (-50 to +150°F)
• Age hardenable

Application

Ni-Span-C Alloy 902 is used in many types of precision apparatus where elastic members are subject to temperature fluctuations.
Resonant vibrating systems such as electro-mechanical filters, tuning forks and vibrating reeds are typical examples of devices where a constant frequency is desired. A zero TEC material may be used for the vibrating member or a slightly positive or negative TEC may be chosen to
compensate for thermal drift due to other components in the device.
Another major application is springs. Here the constant TEC property makes deflection independent of temperature.
Examples are Bourdon tubes, aneroid capsules, geophysical instruments, hairsprings for timing devices, diaphragms, and springs for weighing instruments.
