In high-end 3D logo manufacturing, nickel is often combined with metals like gold or copper through composite electroforming. By alternately depositing different metal layers, both decorative and functional requirements can be achieved. For instance, luxury watch hands use a nickel base layer overlaid with gold plating to balance cost control and visual appeal.

Composite electroforming requires resolving crystalline compatibility between metals. The differing ion deposition rates of nickel and copper may cause interlayer stress, which is mitigated by adding buffer electrolytes to enhance bonding strength. Medical implants employ alternating electroforming of nickel-titanium alloy and pure nickel, leveraging shape-memory alloy properties to create self-expanding structures.

The breakthrough lies in cross-material interface control. Precision optical device brackets fabricated through nickel-silver composite electroforming utilize silver layers for electromagnetic shielding while nickel layers maintain rigidity, avoiding microcracks caused by traditional welding.
