· Sn

Tin (Sn) is a soft, malleable metal with a silvery appearance, known for its corrosion resistance and low toxicity compared to other metallic alternatives. It is primarily used in solder formulations for electronics assembly, coating applications to prevent corrosion (tin plating), and as a alloying element in bronzes and other specialty alloys. Engineers select tin for applications requiring reliable joint formation in PCBs, protection of steel and copper substrates, and situations where lead-free compositions are mandated by regulation or design requirement.

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.
