· SnPt3

SnPt3 is an intermetallic compound combining tin and platinum in a 1:3 ratio, belonging to the family of precious metal alloys with ordered crystal structures. This material is primarily of research and specialized industrial interest, valued in applications requiring exceptional corrosion resistance, thermal stability, and wear performance where platinum's noble character and tin's lightweight contribution create a unique property balance. Its use is limited to high-value sectors such as catalysis, electronics contacts, and specialized aerospace or chemical processing equipment where cost is secondary to reliability and material performance.

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.
