· Ti1 Al1 Fe1 Co1

Ti₁Al₁Fe₁Co₁ is an equiatomic high-entropy alloy (HEA) combining titanium, aluminum, iron, and cobalt in near-equal proportions, classified here as a semiconductor material. This composition sits at the intersection of lightweight structural alloys and functional intermetallic research, designed to explore how multi-principal-element systems can achieve tailored strength-to-weight ratios and potential electronic properties beyond conventional binary or ternary alloys. While not yet established in mainstream production, Ti-Al-Fe-Co alloys are actively investigated for aerospace and energy applications where conventional titanium or cobalt alloys reach performance limits, and for emerging magnetoelectronic or catalytic applications leveraging the alloy's complex phase stability.

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.
