· JVASP-56603· Zr5Al4

Zr5Al4 is an intermetallic compound in the zirconium-aluminum system, representing a higher-aluminum variant of zirconium aluminide phases. This material is primarily of research and exploratory interest rather than established production use, studied for its potential in high-temperature structural applications where lightweight intermetallics could offer advantages over conventional superalloys or refractory metals. Its relevance lies in the zirconium-aluminum family's promise for elevated-temperature service in aerospace and energy sectors, though industrial adoption remains limited compared to established nickel-based or titanium-based alternatives.

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.
