· JVASP-100385· Hf2AlSi

Hf2AlSi is a hafnium-aluminum-silicon intermetallic compound belonging to the refractory metal alloy family, designed for high-temperature structural applications where conventional superalloys reach their limits. This material is primarily developed for aerospace and energy sectors, particularly in applications requiring exceptional thermal stability, oxidation resistance, and mechanical performance at elevated temperatures—such as turbine engine components, hypersonic vehicle structures, and next-generation power generation systems. Its combination of a refractory base element (hafnium) with light alloying additions positions it as a candidate for weight-critical, high-temperature applications where nickel-based superalloys or titanium allooys become insufficient.

Export Control

RoHS, REACH, and Prop 65 statuses are validated against official substance lists (ECHA SVHC Candidate List, OEHHA Prop 65, RoHS Annex II). Other regulations are estimated from composition and material classification. All screening is a starting point for due diligence — always verify with your supplier before making compliance decisions.
