· Al3Tc

Al3Tc is an intermetallic compound in the aluminum-technetium system, representing a research-phase material rather than an established commercial alloy. This material belongs to the family of lightweight intermetallics being explored for high-temperature structural applications where conventional aluminum alloys reach their performance limits. Al3Tc is of primary interest in aerospace and advanced materials research contexts, where its potential for elevated-temperature strength and relatively low density compared to refractory metals could offer weight savings in specialized applications; however, it remains largely in the experimental phase with limited industrial deployment due to challenges in manufacturing, reproducibility, and the scarcity of technetium.

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.
