· Pr11Co89

Pr11Co89 is a rare-earth–cobalt intermetallic compound belonging to the family of permanent magnet materials, where praseodymium provides magnetic hardness and cobalt enhances saturation magnetization and thermal stability. This material is primarily explored in high-temperature magnetic applications and specialized permanent magnet systems, particularly where cobalt-rich rare-earth magnets are engineered for enhanced coercivity and Curie temperature compared to standard NdFeB magnets; it represents a research-focused composition rather than a widely commercialized alloy, making it of interest for advanced aerospace, automotive, and energy applications requiring magnets that maintain performance at elevated temperatures.

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.
