· Al21Pt8

Al21Pt8 is an intermetallic compound in the aluminum-platinum system, representing a high-platinum-content phase that combines lightweight aluminum with noble metal properties. This material is primarily of research and development interest rather than established industrial production, studied for applications requiring exceptional stability, corrosion resistance, and high-temperature performance where conventional aluminum alloys fall short. The platinum content makes it prohibitively expensive for commodity applications, but it remains relevant for specialized aerospace, catalytic, and high-reliability systems where performance justifies material cost and where the intermetallic's ordered crystal structure provides superior creep resistance and oxidation protection compared to conventional Al alloys or pure Pt.

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.
