· JVASP-8026· UNi5

UNi5 is a nickel-based superalloy belonging to the family of precipitation-hardened, high-temperature metals designed for extreme thermal and mechanical loading. This alloy is used primarily in aerospace and power generation industries for critical rotating components that must withstand sustained elevated temperatures while maintaining structural integrity. Engineers select UNi5 when conventional nickel alloys prove insufficient, particularly in applications where creep resistance, fatigue performance, and thermal cycling endurance are mission-critical.

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.
