HoCo5
metal· JVASP-14551· HoCo5
HoCo5 is a hardmetal compound in the cobalt-rich transition metal family, likely an intermetallic or composite material combining holmium or iron with cobalt. This material is primarily of interest in magnetic applications and advanced materials research, where the cobalt content provides ferromagnetic properties and the rare-earth or alloying element enhances coercivity and thermal stability. Engineers select materials in this family for high-performance permanent magnet systems and specialized aerospace or electronics applications where strong magnetic behavior and resistance to demagnetization at elevated temperatures are critical.

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.
