Plated to perform
More than 200 years since its invention, electroplating remains a vital technique in manufacturing, enabling the properties of components to be enhanced from being coated with a thin layer of metal.
As products and components become increasingly sophisticated and miniaturised, the demands and challenges placed on component materials have escalated. Durability, biocompatibility, corrosion resistance, and conductivity are critical characteristics that can determine the success of connectors, watchparts, medical implants, and sensors. Electroplating enables these components to meet stringent industry requirements, supporting both functional and visual characteristics.
Alleima, a leader in advanced materials technology, has long been at the forefront of electroplating. Drawing on decades of expertise, the company continues to innovate and refine its processes, ensuring its electroplating solutions meet the evolving needs of its partners.
We apply single or multiple metallic coatings to enhance electrical performance, acid resistance, and visual appearance. Our capabilities include barrel and rack plating for components, as well as reel-to-reel plating for wire—ensuring precision and quality for every application..
With our ability to electroplate micro components, we can make state-of-the-art metallic coatings on tiny parts.

When to electroplate wire or components?
- Soft gold deposits are typically required for applications like ultrasonic wire bonding and static contact materials.
- Hard gold deposits are more common in dynamic contact applications.
- Nickel plating can be used as a diffusion barrier between the underlying base metal and gold plating layer when the modified surface is exposed to elevated temperatures.
- Nickel as an outer surface layer is an effective surface lubricant as well as a corrosion enhancement layer.
- Silver can be used to enhance the electrical properties of the wire and well as providing a more active surface for joining or other processes.
