High purity for critical service: Hf + Zr > 99.98%, Zr < 1% for reliable neutron absorption and high-purity thin film processes.
Precision control: Thickness 0.01–0.5 mm, tolerance ±0.01 mm, burr-free and oil-free for precision assemblies and cleanroom use.
Flexible formats: Coiled foil for continuous production or cut-to-length strip for custom builds; aligned with semiconductor, nuclear and aerospace workflows.
Global compliance: Produced to ASTM B776, ISO 7233 and compatible with ASTM/ASME/MIL frameworks for straightforward qualification.
Nuclear energy: Control rods, neutron absorbers and shielding elements.
Aerospace: Components exposed to high temperatures (up to ~2233°C) in engines and nozzles.
Semiconductor: Base material for HfO₂ thin films and high-k dielectric layers.
Chemical composition analysis (Hf/Zr ratio & impurities)
Dimensional and thickness tolerance checks
Surface inspection (burr-free, oil-free, defect control)
Packaging: Wooden or plywood cases, or custom protective packing to prevent contamination and mechanical damage.
Shipping: Global delivery via trusted carriers; schedules coordinated with project timelines.
LuminaTitanium delivers high-performance hafnium foil and strip for nuclear, aerospace and semiconductor applications. Manufactured by cold rolling and annealing to ASTM B776 / ISO 7233, our hafnium foil offers tightly controlled thickness, ultra-low zirconium content and clean, burr-free surfaces to support critical neutron absorption and advanced thin-film processes.
