Hf9BW4
metal· JVASP-139852· Hf9BW4
Hf9BW4 is a hafnium-based refractory metal alloy containing tungsten and boron, designed for extreme-temperature and high-strength applications. This material belongs to the family of ultra-high-temperature ceramics and refractory alloys, which are typically employed in aerospace, nuclear, and specialized industrial environments where conventional superalloys reach their performance limits. The addition of tungsten and boron to hafnium enhances hardness, melting point, and oxidation resistance, making it particularly valuable for applications demanding exceptional thermal stability and structural integrity at temperatures where most competing materials degrade.

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.
