The process for manufacturing Ag-sheathed multifilament superconducting wires was investigated. Bi2Sr1.7CaCu2Ox, Pb-doped Bi2Sr2Ca2Cu3Ox, or YBa2Cu3Ox powders were packed into Ag tubes and swaged into long wires. Pieces were cut from each wire, packed into a second Ag tube and swaged or rolled into multifilament wires. Each wire was then sintered to produce a superconductor. Processing considerations included the sheath workability, effects of compacting and residual stresses, and heat treatment schedules. The superconducting properties of the Bi-based wires were superior to those of the YBa2Cu3Ox wires at 4.2 K, but not at 77 K.
