Be4AlNi
metal· JVASP-102798· Be4AlNi
Be₄AlNi is a quaternary intermetallic compound combining beryllium, aluminum, and nickel—a lightweight metal system typically studied for high-strength, low-density structural applications. This material family represents research-phase development rather than established commercial use, with primary interest in aerospace and defense sectors where weight reduction and elevated-temperature stability are critical; the beryllium component provides exceptional stiffness and low density while the nickel and aluminum additions enhance mechanical performance and thermal characteristics compared to pure beryllium or conventional aluminum alloys.

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.
