semiconductor

· Al1 Fe1

Al₁Fe₁ is an intermetallic compound in the aluminum-iron system, classified as a semiconductor with a 1:1 stoichiometric composition. This material represents an experimental or specialized research compound rather than a widely commercialized alloy, and belongs to the family of lightweight intermetallic semiconductors that combine metallic and semiconducting properties. Interest in Al-Fe intermetallics stems from potential applications in electronic devices and thermoelectric systems where the combination of thermal conductivity from the metallic phase and electronic band structure control is valuable.

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.
