· CrAs

CrAs is a chromium arsenide intermetallic compound that forms a metallic ceramic material with relatively high hardness and stiffness. While not widely established in conventional engineering applications, CrAs is primarily investigated in materials research for potential use in high-temperature structural applications, wear-resistant coatings, and semiconductor-related studies due to its transition metal composition and crystallographic properties.

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.
