· JVASP-108159· AlSi3W2

AlSi3W2 is an aluminum-silicon-tungsten composite alloy designed to combine the lightweight advantages of aluminum with tungsten's high density and hardness. This material represents a research-phase composite engineered for applications requiring enhanced wear resistance, thermal stability, or radiation shielding in a relatively dense aluminum matrix. While not yet a widely established commercial alloy, materials in this family are being explored for specialized aerospace, defense, and high-temperature applications where conventional aluminum alloys fall short.

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.
