· CuFeS2

CuFeS₂ (chalcopyrite) is a naturally occurring copper-iron sulfide mineral and the primary ore of copper, composed of copper, iron, and sulfur in a fixed stoichiometric ratio. It is industrially significant as the dominant source material for copper extraction via flotation and pyrometallurgical processing, and is increasingly studied as a semiconductor material for photovoltaic and thermoelectric applications due to its direct bandgap and earth-abundant composition. Engineers select CuFeS₂-based materials over synthetic alternatives when cost-effectiveness and large-scale availability are critical, or in emerging research contexts where high-performance semiconductors must be manufactured from abundant elements rather than scarce materials like cadmium or gallium.

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.
