Gadolinium Spooled Wire

Gadolinium Spooled Wire is a precision-drawn rare-earth metal product engineered for high magnetic performance, flexibility, and integration into advanced device architectures. Composed of 99.9% pure gadolinium, it can be manufactured with controlled microstructural phases to enhance workability and mechanical stability. This wire form is essential in magnetic refrigeration systems, specialized heat exchangers, and precision sensing devices. Specific applications include clad metal-covered gadolinium wires for corrosion-resistant magnetocaloric devices, integration into high-strength aluminum alloy conductors where trace Gd improves conductivity and durability, and utilization in laboratory-scale superconducting and magnetic assemblies. In research, gadolinium spooled wire supports the development of energy-efficient cooling technologies, advanced electrical transmission materials, and magneto-functional prototypes. Its continuous form factor, tunable properties, and compatibility with advanced processing reinforce its value in both industrial manufacturing and scientific experimentation.
