Zinc-nickel alloy plating (Zn-Ni, typically 10–16% nickel) deposits a zinc-nickel coating that offers significantly better corrosion resistance than conventional zinc plating, with stable friction behavior and good paint adhesion. It is commonly specified for automotive and fastener applications where salt-spray performance and coating consistency matter.

Corrosion performance is verified per the agreed test method and specification (e.g. neutral salt spray hours) on the actual part geometry. Results depend on coating thickness, nickel content, passivation type and substrate condition — the final requirement is confirmed against your drawing and control plan.

Barrel plating suits small and medium-sized components such as fasteners, screws, nuts, bushings, sleeves, brackets and stamped parts that can be tumbled safely. Larger or geometry-sensitive parts are evaluated for rack plating instead.

Yes. Passivation options include black, blue, rainbow (yellow) and transparent finishes, selected per appearance and corrosion requirements. The passivation type is confirmed against the drawing and functional specification.

The plant is certified to ISO 9001 and IATF 16949 quality management systems, and can support customer-specific documentation (PPAP elements, IMDS, RoHS-related records) when part of the project requirements.

Balford reviews the plating requirement together with the part drawing before tooling — coating thickness, masking needs, hydrogen embrittlement risk and dimensional effects are considered in the process and inspection plan. Plating is then coordinated with the approved production schedule.
