An annular fire ring comprises an alloy of beryllium copper. Before the alloy is subject to precipitation hardening at elevated temperatures, the ring is placed at an inner periphery of a high temperature opening of a gasket body, wherein the diameter of the ring is greater than a thickness of the gasket body. The resulting gasket is then disposed between cooperating mechanical components. The mechanical components are clamped together, plastically deforming the fire ring. Then the ring is heated, causing precipitation hardening of the alloy.
