· JVASP-17872· HoCoC

HoCoC is a cobalt-based alloy incorporating holmium and carbon, belonging to the family of high-performance metallic compounds designed for extreme environments and specialized applications. This material is primarily investigated for use in high-temperature structural applications, magnetic devices, and wear-resistant components where the combination of cobalt's inherent strength with holmium's rare-earth properties offers potential advantages over conventional superalloys. The addition of carbon enhances hardness and wear resistance, making HoCoC a candidate material for aerospace, nuclear, and advanced manufacturing contexts where conventional alternatives may reach performance limitations.

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.
