· JVASP-125562· Al3W

Al₃W is an intermetallic compound combining aluminum with tungsten, forming a hard ceramic-like phase typically found as a constituent in aluminum-tungsten composite systems or as a research material in advanced metallurgy. While not a primary commercial alloy, Al₃W phases appear in specialized high-temperature and wear-resistant applications, particularly in composite materials and refractory research where the combination of aluminum's light weight with tungsten's exceptional hardness and melting point offers potential benefits. Engineers considering this material should recognize it primarily as a research or specialty compound rather than an off-the-shelf engineering alloy, valuable mainly in applications demanding extreme hardness or thermal stability in composite form.

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.
