CdNi
metal· JVASP-127766· CdNi
CdNi is a cadmium-nickel alloy that combines the corrosion resistance and work-hardening characteristics of nickel with cadmium's low friction and plating properties. Historically used in aerospace fasteners, electrical contacts, and plating applications where corrosion resistance and wear resistance were critical, though cadmium use has declined significantly due to environmental and health regulations in most developed markets. Modern applications are limited and primarily restricted to specialized aerospace and defense contexts where legacy specifications remain in effect; nickel-based alternatives (such as pure nickel or nickel-copper alloys) have largely replaced CdNi in commercial industries.

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.
