· JVASP-37032· TiFeCoSi

TiFeCoSi is a quaternary intermetallic alloy combining titanium, iron, cobalt, and silicon—a composition designed to explore high-strength, lightweight material systems beyond conventional binary or ternary alloys. This material family is primarily of research interest, with applications being investigated in aerospace and high-temperature structural components where the synergistic properties of these transition metals could provide improved strength-to-weight ratios and thermal stability compared to traditional titanium alloys or iron-based superalloys.

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.
