· Al4W

Al₄W is an intermetallic compound combining aluminum with tungsten, belonging to the family of lightweight-refractory metal composites. This material is primarily of research interest for high-temperature applications where both low density and refractory properties are valuable, though industrial adoption remains limited compared to established superalloys. Al₄W and related aluminum-tungsten phases are explored in aerospace and materials science contexts for potential use in extreme environments where the combination of aluminum's weight advantage and tungsten's thermal stability could offer benefits over conventional nickel- or cobalt-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.
