· Pt

Platinum is a noble metal prized for its exceptional corrosion resistance, high density, and stability across extreme temperature ranges. It is widely used in catalytic converters, chemical processing equipment, electrodes, and high-reliability electronic contacts, where its resistance to oxidation and chemical attack justifies its premium cost. Engineers select platinum when material failure cannot be tolerated in harsh corrosive environments or when long service life and minimal maintenance are critical priorities.

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.
