· FeNiSi

FeNiSi is an iron-nickel-silicon ternary alloy that combines ferromagnetic iron and nickel with silicon additions to improve strength, corrosion resistance, or specific magnetic properties. This alloy family is used primarily in electrical and magnetic applications where controlled permeability, low core loss, or high saturation induction are required, as well as in corrosion-resistant structural components where silicon enhances oxidation resistance and mechanical strength.

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.
