Europium Spooled Wire

Europium Spooled Wire is a form of pure metal wire that Goodfellow offers in its range of products. This rare earth metal wire comes in at least 3 variations that differ in diameter and length. Europium wire's unique properties like conductivity, ductility, and low corrosion make it useful for specialized electronics and research applications. The wire can serve as interconnects in devices where high performance is needed. Europium's sensitivity to magnetism also allows it to function as sensors in instruments.
