Pd
metal· Pd
Palladium is a noble metal belonging to the platinum group, prized for its exceptional corrosion resistance, catalytic properties, and ability to absorb and transmit hydrogen. It is widely used in catalytic converters, electronics, dentistry, and chemical processing where its resistance to oxidation and chemical attack is critical. Engineers select palladium over base metals when superior corrosion resistance, biocompatibility, or catalytic function justifies its cost, and over platinum when slightly lower density and expense are acceptable trade-offs.

Regulatory Screening
Environmental
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.
