· Pt3Pb

Pt3Pb is an intermetallic compound combining platinum and lead in a 3:1 ratio, forming a dense metallic phase with high stiffness. This material belongs to the platinum-group intermetallics family and is primarily of research and specialized industrial interest, valued for applications requiring the corrosion resistance and thermal stability of platinum combined with modified mechanical and physical properties. Pt3Pb appears in fuel cell catalyst research, high-temperature structural applications, and specialized electronics where platinum's noble-metal properties must be optimized for cost or performance—though its lead content restricts use in many modern applications due to environmental and toxicity concerns.

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.
