· Sn4Pt

Sn4Pt is an intermetallic compound combining tin and platinum in a fixed stoichiometric ratio, belonging to the class of high-density metal alloys with notable stiffness characteristics. This material is primarily investigated in research contexts for electronics and thermal management applications where platinum's corrosion resistance and thermal conductivity combine with tin's availability and processing advantages. The intermetallic structure makes it relevant for high-reliability applications such as solder systems, contact materials, and composite reinforcement in aerospace or microelectronics where conventional tin-lead or lead-free solders reach thermal or mechanical limits.

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.
