· JVASP-20764· Ni5Sb2

Ni₅Sb₂ is an intermetallic compound in the nickel-antimony system, characterized by a defined stoichiometric crystal structure that combines nickel's corrosion resistance with antimony's hardening effects. This material is primarily of research and specialized industrial interest, appearing in thermoelectric applications, semiconductor contacts, and high-temperature coating systems where the intermetallic phase provides enhanced hardness and thermal stability compared to pure nickel or simple binary alloys. Engineers would consider Ni₅Sb₂ when seeking improved wear resistance or thermal performance in niche applications, though its brittleness and limited ductility relative to conventional nickel alloys restrict its use to specific high-value or high-temperature scenarios.

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.
