· JVASP-133462· HfAlMo

HfAlMo is a refractory metal alloy combining hafnium, aluminum, and molybdenum, designed for extreme high-temperature applications where oxidation resistance and structural stability are critical. This alloy system is primarily explored in aerospace and advanced propulsion contexts, particularly for applications like rocket nozzles, hypersonic vehicle components, and next-generation turbine systems where conventional superalloys reach their thermal limits. The hafnium-aluminum-molybdenum combination offers potential advantages in thermal shock resistance and creep performance at temperatures where nickel- and cobalt-based superalloys begin to degrade, making it a candidate material for researchers developing engines and structures operating above 1500°C.

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.
