· Al1 Fe2 W1

Al₁Fe₂W₁ is an intermetallic compound combining aluminum, iron, and tungsten in a 1:2:1 stoichiometric ratio. This ternary intermetallic belongs to the family of refractory and high-temperature materials, though it remains largely in the research phase with limited commercial deployment. The material is of interest for high-temperature structural applications and wear-resistant coatings where the combination of lightweight aluminum, iron's cost-effectiveness, and tungsten's hardness and melting point elevation might offer advantages over conventional binary alloys or pure metals.

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.
