· Ni4B3

Ni4B3 is a nickel boride intermetallic compound that belongs to the family of transition metal borides, which are known for high hardness and thermal stability. This material is primarily of research and specialized industrial interest, used in hard coatings, wear-resistant applications, and high-temperature applications where boride ceramics provide superior hardness compared to conventional alloys. Ni4B3 and related nickel borides are valued in cutting tool technology, surface hardening, and thermal barrier systems, though they remain less common than iron or tungsten borides in commodity applications.

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.
