· JVASP-100431· AlReSi

AlReSi is an aluminum-rhenium-silicon ternary alloy that combines the lightweight characteristics of aluminum with the high-temperature strength and refractory properties of rhenium and silicon. This material is primarily of research and developmental interest for advanced aerospace and high-temperature applications where exceptional strength-to-weight ratios and thermal stability are critical, though industrial adoption remains limited compared to established superalloys.

Regulatory Screening

Environmental

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.
