HPM® Ni 42 Nickel-Iron Alloy

nickel iron alloy, thermal expansion, electronic circuits

Description

HPM® Ni 42 is a Nickel-Iron alloy with a thermal expansion coefficient suitable for matching to the ceramic chip in numerous miniature electronic circuits The alloy is readily formed from the annealed temper and can be welded or brazed by standard methods. The alloy is not corrosion resistant at 20°C when exposed to a moist or salt-containing atmosphere. Available Sizes: HPM® Ni 42 is available from Hamilton Precision Metals as strip product in thicknesses from 0.001” to 0.050” (0.0254 mm to 1.27 mm) in widths up to 12.0” (304.8 mm). The material conforms to ASTM F30 and UNS K94100.
