Yttrium wire is a high purity metal wire produced by Goodfellow for research and development applications. Available in 10 different diameter variations from 0.05mm to 1mm, yttrium wire offers excellent corrosion resistance and high temperature strength. With a melting point of 1522°C, yttrium wire is commonly used in high temperature thermocouples and as a filament material in vacuum tubes. The high absorption cross-section of yttrium also makes it useful for dosimetry applications in the nuclear industry. Overall, Goodfellow's range of yttrium wire provides researchers with a versatile high purity metal wire for testing and development across a variety of industries.
