· JVASP-51099· ZnFePb

ZnFePb is a ternary alloy system combining zinc, iron, and lead—a composition space historically explored for bearing materials, solder applications, and specialized wear-resistant components. This alloy family offers a balance of sliding friction characteristics and conformability typical of bearing bronze-class materials, though modern use is limited due to lead toxicity and environmental regulations that have displaced many Pb-containing alloys in new designs. Engineers may encounter ZnFePb in legacy equipment maintenance, heritage metallurgy studies, or niche applications where lead's specific tribological properties remain technically justified and regulatory pathways exist.

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.
