Cr7C3
metal· Cr7C3
Cr7C3 is a chromium carbide ceramic compound that forms as a constituent phase in chromium-rich carbide systems, typically appearing in hardened steels, cast irons, and wear-resistant coatings rather than as a standalone material. This phase is valued in industrial applications where extreme hardness and wear resistance are critical, particularly in tools, dies, and coating systems that experience abrasive contact; it is notably harder and more chemically stable than softer carbide phases but more brittle than metallic matrices, making careful microstructural control essential.

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.
