· Bi92Sb8

Bi92Sb8 is a bismuth-antimony binary alloy composed of 92% bismuth and 8% antimony, belonging to the family of low-melting-point metal alloys. This material is primarily investigated for thermoelectric applications and specialty thermal management systems, where its relatively low melting point and bismuth-rich composition enable use in temperature-sensitive applications requiring reliable phase stability and predictable thermal behavior. The alloy is notable in research contexts for thermoelectric energy conversion and as a potential replacement for lead-containing solders in applications where low processing temperatures are critical, though it remains more specialized than commercial alternatives like tin-based or lead-free solders.

Regulatory Screening

Environmental

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.
