· JVASP-111375· CrRu

CrRu is a chromium-ruthenium alloy combining two refractory transition metals known for high hardness and corrosion resistance. While not widely deployed as a commercial engineering alloy, CrRu systems are investigated in research contexts for applications requiring extreme hardness, wear resistance, and oxidation stability—particularly in hard coatings, wear-resistant surfaces, and high-temperature corrosion barriers where conventional stainless steels or nickel-based superalloys fall short.

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.
