· Al3Pt5

Al3Pt5 is an intermetallic compound combining aluminum and platinum in a fixed stoichiometric ratio, belonging to the family of high-performance metallic intermetallics. This material is primarily of research and specialized industrial interest, valued in applications requiring exceptional hardness, thermal stability, and corrosion resistance where the cost of platinum content is justified by performance demands. Al3Pt5 represents the broader class of platinum-based intermetallics explored for extreme-environment applications, particularly in aerospace and catalytic systems where conventional superalloys reach their limits.

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.
