· FeNiSb

FeNiSb is an intermetallic compound combining iron, nickel, and antimony, belonging to the half-Heusler alloy family. This material is primarily studied in thermoelectric applications where it demonstrates potential for solid-state heat-to-electricity conversion, particularly in medium-temperature operating ranges. FeNiSb offers an alternative to traditional thermoelectric materials with the advantage of using relatively abundant constituent elements, making it attractive for waste heat recovery and power generation in automotive and industrial settings where cost and scalability compete with performance requirements.

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.
