An alloy that contains at least two metals and can be used as a substrate (901) for a superconductor (900) is disclosed. The alloy can contain an oxide former. The alloy can have biaxial or cube texture. The substrate can be used in a multilayer superconductor, which can further include one or more buffer layer (902) disposed between the substrate and the superconductor material (903). The alloys can be made by a process that involves first rolling the alloy, and then annealing the alloy. A relatively large volume percentage of the alloy can be formed of grains having a biaxial or cube structure.
