· Al7La2

Al7La2 is an aluminum-lanthanum intermetallic compound, representing a rare-earth-reinforced aluminum alloy system designed to improve high-temperature strength and creep resistance compared to conventional aluminum alloys. This material is primarily of research and development interest rather than established commercial production, with potential applications in aerospace and automotive sectors where elevated-temperature performance beyond conventional Al-Cu or Al-Mg systems is required. The lanthanum addition strategy addresses a key limitation of traditional aluminum alloys—their rapid strength loss above ~200°C—making Al7La2 notable as a candidate for next-generation cast or wrought components operating in thermally demanding environments.

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.
