Waspaloy® Foil

Waspaloy® Foil delivers an age-hardenable, nickel-base superalloy in a thin sheet that endures hot gases, oxidation, and mechanical stress where stainless foils quickly relax. The alloy’s strength at temperature and corrosion resistance make it a dependable choice for light, all-metal thermal barriers and shields that live close to burners, combustors, and exhaust streams. Aerospace, energy, and high-temperature process industries use Waspaloy foil for shims, corrugated wraps and bellows, honeycomb or labyrinth seals, and robust masks for bake-outs or spray operations. It forms, spot-welds, and corrugates cleanly, allowing designers to balance stiffness and compliance in compact envelopes without moving to heavy plate. In test rigs and production hardware, the foil helps maintain clamp load and sealing pressure through repeated heat cycles, reducing rework and downtime. For engineers pushing temperature and duty cycle, Waspaloy foil offers a reliable route to durable thermal management and mechanical retention in demanding assemblies.
