Abstract
A process for producing a cube textured foil is described. The process includes providing a cube textured metal foil M. The process further includes electroplating an epitaxial layer of an alloy on the foil M, whereby the epitaxial layer substantially replicates the cube texture of the metal foil M. The process further includes electroplating a non-epitaxial layer of an alloy on the epitaxial layer. The process further includes separating the electroplated alloy from the cube textured metal foil M to obtain an electro-formed alloy with one cube textured surface.

A process for producing a cube textured foil, comprising:
- providing a cube textured metal foil M, wherein the metal foil M comprises Cu, Ni, NiFe, or any alloy thereof;
- electroplating an epitaxial, non-magnetic layer of a nickel alloy on the foil M, whereby the epitaxial layer substantially replicates the cube texture of the metal foil M;
- and
- electroplating at least one non-epitaxial, non-magnetic layer of the nickel alloy on the epitaxial layer.
A foil comprising an epitaxial, non-magnetic layer of Ni(1-X-Y)BXCY having a cube texture overlying a non-epitaxial, non-magnetic layer of Ni(1-X-Y)BXCY, wherein B and C are selected from the group consisting of W, Mo, and Cr, and wherein X is 0.02-0.14 and Y is 0-0.14 and a cube textured metal foil M overlying the epitaxial non-magnetic layer, the epitaxial non-magnetic layer substantially replicating the cube texture of the metal foil M.
A process for producing a cube textured foil, comprising:
- providing a cube textured metal foil M;
- electroplating an epitaxial layer of non-magnetic alloy on the foil M, whereby the epitaxial layer substantially replicates the cube texture of the metal foil M;
- wherein the epitaxial alloy layer comprises Ni(1-X-Y)BXCY;
- and
- electroplating at least one non-epitaxial, non-magnetic layer of Ni(1-X-Y)BXCY on the epitaxial layer;
- wherein B and C are elements selected from the group consisting of W, Mo, and Cr;
- and wherein X is 0.02-0.14 and Y is 0-0.14, in atomic fractions.
A foil S comprising an epitaxial, non-magnetic layer of a nickel alloy having a cube texture overlying a non-epitaxial, non-magnetic layer of the nickel alloy and a cube textured metal foil M overlying the epitaxial, non-magnetic layer, the epitaxial, non-magnetic layer substantially replicating the cube texture of the metal foil M, wherein the metal foil M comprises Cu, Ni, NiFe, or any alloy thereof.
