Soft brazing - Import export

Precision C is a heat treatable Nickel-Iron Alloy used in critical diaphragm applications, such as, metal diaphragms for aerospace sensors and burst discs. The alloy composition provides a unique constant elastic modulus value over a temperature range of -50ºF to 150ºF. Precision C can be readily formed from the annealed temper. It has a work hardening rate similar to austenitic stainless steel. The material can be joined by TIG, EB, and resistance welding as well as by brazing and soft solder technique. The heat treatment of Precision C can be adjusted to produce the desired value for the thermoelastic coefficient at or near zero. The elevated strength in the heat treated temper results in low mechanical hysteresis and low drift. Available Sizes: Precision C is available from Hamilton Precision Metals as strip product in thickness from 0.0005” to 0.040” (0.0127 mm to 1.016 mm) and widths up to 8.0” (203.2 mm). The material conforms to ASM 5221 and UNS N09902.
