Havar® Disk

Havar® Disk, a cobalt-chromium alloy, is engineered for aerospace, military, and medical applications requiring high strength, fatigue resistance, and corrosion stability. It is widely used in actuators, springs, and structural components exposed to extreme conditions. In nuclear technology, Havar® is essential for medical radioisotope production targets, while the semiconductor industry utilizes it in wafer-processing equipment for its chemical inertness. Its role in precision instrumentation, X-ray windows, and high-performance sensors highlights its reliability under demanding mechanical and environmental stresses. With excellent durability and resistance to deformation, Havar® is a critical material in aerospace engineering, medical devices, laboratory research, and advanced industrial applications.
