· ZrNi3

ZrNi3 is an intermetallic compound belonging to the zirconium-nickel system, characterized by a fixed stoichiometric ratio that creates a brittle, high-strength phase used primarily in research and specialized industrial applications. This material is investigated for use in high-temperature structural applications and as a reinforcing phase in composite systems, where its high elastic stiffness and thermal stability are advantageous; however, its brittleness and processing challenges limit adoption compared to conventional superalloys or titanium alloys. Engineers consider ZrNi3 primarily in exploratory aerospace and nuclear thermal management contexts where marginal weight savings or extreme temperature resistance justify custom alloy development.

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.
