· JVASP-15120· Cr3GaN

Cr₃GaN is a ternary ceramic-metallic compound combining chromium, gallium, and nitrogen, representing an emerging class of hard ceramic materials with metallic bonding character. This material exists primarily in research and development contexts as part of the broader family of nitride ceramics and MAX-phase related compounds, explored for applications requiring high hardness, thermal stability, and wear resistance at elevated temperatures. Compared to conventional tool steels and tungsten carbides, Cr₃GaN offers potential advantages in thermal shock resistance and reduced brittleness, though industrial adoption remains limited and material availability is typically restricted to research quantities.

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.
