· AlPt

AlPt is an intermetallic compound combining aluminum and platinum, belonging to the class of ordered metallic intermetallics. This material is primarily of research and high-performance engineering interest, valued for its combination of relatively low density with the hardness and corrosion resistance associated with platinum. AlPt and related Al-Pt systems are investigated for aerospace applications, wear-resistant coatings, and high-temperature structural applications where the noble-metal component provides oxidation resistance while aluminum reduces overall weight compared to pure platinum.

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.
