HfBeCo4
metal· JVASP-64936· HfBeCo4
HfBeCo4 is a high-entropy or multi-principal element metallic alloy combining hafnium, beryllium, and cobalt in a 1:1:4 compositional ratio. This is a research-phase material primarily of academic interest, developed to explore the properties of refractory metal systems with controlled intermetallic phases. The hafnium-beryllium-cobalt system offers potential for extreme-temperature applications and specialized aerospace or nuclear contexts where lightweight refractory character is valuable, though industrial adoption remains limited and material behavior requires further characterization.

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.
