Method of producing copper clad superconductors

Patent ·
OSTI ID:7320180

Copper cladding is provided on alloy or compound superconductors such as niobium containing materials in strip or wire form by bonding the superconductive material to the copper through an intermediate aluminum bonding layer. Aluminum foil is placed about the superconductive material and then inserted into a copper sheath and bonding occurs in the rolling thereof or drawing it into the wire. Heat treatment is subsequently employed to improve the superconductive properties of the alloy or to react the constituents to form the superconductive compound.
