· Sr8Fe3N8

Sr8Fe3N8 is an iron-strontium nitride intermetallic compound, part of the rare-earth-free nitride family being explored for magnetic and structural applications. This material is primarily a research compound rather than an established commercial product, developed to investigate alternatives to rare-earth magnets and high-performance alloys, particularly where cost reduction or supply-chain resilience is critical. The strontium-iron nitride system is notable for combining relatively low density with potential for hard-magnetic or structural reinforcement roles, making it a candidate for advanced permanent magnets, magnetic recording media, or lightweight high-strength composites where traditional rare-earth elements are impractical.

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.
