· JVASP-57743· Pr2Co7B3

Pr2Co7B3 is a rare-earth cobalt boride intermetallic compound that belongs to the family of hard magnetic and wear-resistant materials. This material is primarily investigated in research and development contexts for applications requiring high hardness, thermal stability, and magnetic properties, particularly where traditional tungsten carbides or cobalt-based hardmetals may be limited by cost or performance at elevated temperatures. The combination of praseodymium, cobalt, and boron creates a dense intermetallic phase that offers potential advantages in cutting tools, wear-resistant coatings, and permanent magnet applications where superior creep resistance or magnetic performance under demanding conditions is needed.

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.
