· AlRe

AlRe is an aluminum-rhenium intermetallic or alloy system combining aluminum's light weight with rhenium's high melting point and strength, creating a material with potential for extreme-temperature applications. While not widely commercialized, this alloy family is of research interest for aerospace and high-performance thermal applications where conventional aluminum alloys reach their limits, particularly where density must remain low while maintaining structural integrity at elevated temperatures.

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.
