Abstract
Abstract A hybrid superconducting material in which superconducting strands, at least partially surrounded by a layer of low resistance normally conducting material, are embedded in a matrix of high resistance normally conducting material. In a specific embodiment, the superconducting strands consist essentially of niobium titanium, individually surrounded by a thin sleeve of copper, and embedded in a matrix of cupro-nickel. The composite is extruded at elevated temperatures and pressure. The wire so formed may be used for electromagnet coils designed to function in a cryogenic system.
