PdAu
metal· JVASP-105422· PdAu
PdAu is a palladium-gold alloy that combines the chemical inertness and catalytic properties of both precious metals. It is primarily used in catalysis, electronics, and specialized medical/dental applications where corrosion resistance and biocompatibility are critical; the palladium component enhances hydrogen permeability and catalytic activity while gold provides stability and aesthetic properties. Engineers select this alloy over single-metal alternatives when applications demand both chemical durability and functional performance in aggressive environments, though cost and limited availability restrict it to high-value specialized markets.

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.
