Havar® is a heat treatable cobalt based alloy that provides very high strength at high temperatures. Havar® has excellent corrosion resistance and is non-magnetic. Forming cold rolled Havar® requires a large radius equal to 8 times the material thickness prior to age hardening. Havar® can be joined using both welding and soldering techniques. Ultimate endurance life is achieved by heat treating the alloy at 540°C after 80% cold work. The alloy will retain 75% of room temperature strength up to 500°C. Applications include pressure diaphragms, power springs, gap spacers in magnetic heads, target foils in nuclear physics and the production of radioisotopes for the detection and treatment of cancer.
