· JVASP-68281· BeCuNi2

BeCuNi2 is a beryllium-copper-nickel ternary alloy that combines the high strength and thermal conductivity of beryllium-copper with nickel's corrosion resistance and toughness. This alloy is used in demanding applications requiring a balance of mechanical strength, electrical conductivity, and environmental durability, particularly in aerospace fasteners, connector contacts, and precision spring applications where both performance and reliability under cyclic loading are 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.
