HPM® Ni 36 Nickel-Iron alloy

HPM® Ni 36 is a Nickel-Iron alloy with the lowest thermal expansion of any active alloy from -240°C to 330°C. It is selected when dimensional changes from temperature variation need to be minimized in electronic control devices, such as use within airbag igniters and precision metal stampings. The alloy can be readily formed from the annealed temper.Annealed hardness can be modified to approximately DPH 180 for best blanking characteristic. Grain size can be adjusted to provide the optimum deep drawing characteristic. It can be welded and brazed using conventional methods. Available Sizes: HPM® Ni 36 is available from Hamilton Precision Metals as strip product in thicknesses from 0.0005” to 0.025” (0.0127 mm to 0.635 mm) in widths up to 12.0” (304.8 mm). It is also available in foil as thin as 0.000100” (0.00254 mm) in widths of 4.0” (101.6 mm) maximum. The metal conforms to UNS K93603, ASTM F1684.
