Gold Plating

Advanced Gold Plating for High-Performance Wire Applications

Luma Wire Tech provides precision gold plating solutions for fine wire applications where long-term stability, corrosion resistance, and reliable electrical contact performance are critical.

Unlike many other metals, gold does not oxidize under normal conditions. This unique characteristic allows gold-plated wire to maintain consistent electrical performance over time, making gold a preferred surface engineering solution for applications where reliability cannot be compromised.

Using advanced reel-to-reel electroplating technology, Luma applies highly controlled gold coatings to fine wires ranging from 5 to 200 microns. Plating fine wire with gold can enhance corrosion resistance, improve contact reliability, increase biocompatibility, and support specialized optical and RF-related requirements while preserving the mechanical properties of the base wire.

Whether the goal is improved electrical contact performance, increased corrosion resistance, enhanced biocompatibility, or specialized RF functionality, gold plating remains one of the most proven and versatile surface engineering solutions available for fine wire applications.

Why Gold Plating?

Gold plating is widely used in applications where corrosion resistance, electrical contact performance, and long-term reliability are critical. Because gold does not oxidize under normal or harsh conditions, it helps maintain stable electrical performance over time. These properties make gold plating a preferred choice for medical devices, aerospace systems, sensors, electronics, and other demanding applications.
