· JVASP-151253· FeSiNi

FeSiNi is an iron-silicon-nickel ternary alloy that combines the ferromagnetic properties of iron with the corrosion resistance and work-hardening characteristics of nickel and silicon additions. This material family is primarily employed in electromagnetic applications, precision castings, and specialty structural components where a balance of magnetic performance, corrosion resistance, and moderate strength is required. The addition of silicon and nickel to an iron base enables tailored magnetic permeability and improved environmental durability compared to plain carbon steel, making FeSiNi relevant for industries demanding both functional magnetic properties and extended service life in corrosive or elevated-temperature environments.

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.
