Alloy 360, TD01, N03360, Nibry, Nickel Alloy Strip
Beryllium Nickel 360 is a Beryllium-Nickel alloy capable of high strength through precipitation heat treatment. The excellent spring characteristics to 550°F make it suitable for many of the most demanding electromechanical devices.
The alloy can be readily formed and even deep drawn from the annealed temper. Cold rolled tempers prior to heat treatment can be blanked and folded provided a radius to thickness ratio approaches 2.0.
The optimum heat treatment for highest strength is 925ºF for 2 hours. The material can be joined using conventional TIG methods, silver brazed and soldered.
Available Sizes:
Beryllium Nickel 360 is available as strip product in thicknesses from 0.0005” to 0.025” in (0.0127 to 0.635 mm) widths up to 7.0” (177.8 mm). A foil product is available as thin as 0.000085” (0.002159 mm) and widths of 4.0” (101.6 mm) maximum. The material conforms to UNS N03360.
