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.

Phosphor Bronze A is a Copper base spring material with a good combination of strength, formability, and corrosion resistance. The material is suitable for use in certain contact springs and diaphragms. The alloy has good formability up to moderate strength. It can be soldered, silver brazed, and resistance welded. Available Sizes: Phosphor Bronze A is available from Hamilton Precision Metals as strip products in thicknesses from 0.001” to 0.020” (0.0254 mm to 0.508 mm) in widths up to 12.0” (304.8 mm). The material conforms to ASTM B 103 and UNS C51000.

HPM® 600 is well suited for severe corrosive environments and is oxidation resistant through 2150°F. Such as, metal diaphragms for aerospace sensors, flexible metal foil heaters and metal diaphragms for burst discs. The strength can be increased by cold working. The material has good elevated strength retention through 800°F. The alloy is readily formed in the annealed temper, and can be joined by the standard welding, brazing and soldering processes. Available Sizes: HPM® 600 is available from Hamilton Precision Metals as strip product in thicknesses from 0.0005” to 0.050” (0.0127 mm to 1.27 mm) and width up to 12” (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 material conforms to ASTM B168, AMS 5540, MIL N 23228 and UNS N06600.
