Havar® is a heat treatable Cobalt base alloy that provides very high strength. The alloy has excellent corrosion resistance and is non-magnetic. Applications have included metal diaphragms for aerospace sensors, metal diaphragms for burst discs, power springs, gap spacers in magnetic heads, and target foils in nuclear physics. Forming cold rolled Havar requires large radius (90° Bend – 8 X thickness) prior to age hardening. The joining can be accomplished using both welding and soldering techniques.The ultimate endurance life is achieved by heat treating the alloy at 1000°F after 80% cold work. The alloy will retain 75% of room temperature strength up to 950°F (Figure 1). Available Sizes: Havar® is available from Hamilton Precision Metals as strip product in thicknesses from 0.0005” to 0.025” (0.0127 mm to 0.635 mm) and widths to 7.5” (190.5 mm). A foil product is available in thicknesses down to 0.000060” and widths of 4.0” (101.6 mm). The material corresponds to UNS R30004.
