· SiNi

SiNi is a nickel-silicon intermetallic compound, a binary alloy system combining silicon and nickel that exhibits properties intermediate between ceramic and metallic materials. This material family is primarily explored in research contexts for high-temperature applications and structural applications where the combination of silicon's hardness with nickel's toughness offers potential advantages over conventional superalloys or pure ceramics.

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.
