Industrial Silver Electroplating Services

Silver electroplating is the process of applying a thin coating of silver to an object made of another type of metal. It is one of the oldest and most widely used metalworking techniques, which is widely used in industries such as energy, electronics, automotive, automotive and jewellery.

At Electris Coating Systems, we carry out the silvering process on components made of copper (copper silvering) or aluminium (aluminium silvering). Our specialty is the silver plating of busbars. Thanks to our state-of-the-art, high-tech electroplating plant, we are able to apply a layer of varying thickness: from 1 μm to 50 μm. We electroplate components with a maximum length of 2100 mm.

Industrial silver electroplating has a major impact on improving the corrosion resistance or conductive properties of copper. These modifications make the metals more durable and versatile in various industries.

• Excellent electrical conductivity: as an excellent electrical conductor, silver minimises energy loss and improves the longevity of electrical contacts, especially in environments where other metals can oxidise. It is widely used in wires, connectors and electronic components.
• Corrosion protection: the silver plating process creates a protective layer on the surface of the components, protecting them from corrosion and oxidation. This makes silver-plated components more resistant to weathering and moisture, extending their life.
• Heat resistance: even at high temperatures, a good quality silver coating will not oxidize or degrade, making it an ideal material for high-temperature environments.
• Abrasion resistance: silver plating improves the hardness and abrasion resistance of copper or aluminium parts. This makes them more durable and resistant to mechanical damage, which can be important for usable components such as tools or machine parts.
• Improved antimicrobial properties: silver plating also has antimicrobial properties, which can be beneficial for components that come into contact with human skin or are used in environments where there is a risk of bacterial growth.

Silver Plating Services on Aluminum Parts

Silver plating enhances the performance of aluminum by significantly improving its conductivity and corrosion resistance. At Electris, we specialize in coating aluminum busbars and structural components, ensuring uniform coverage and long-lasting durability. Ideal for use in energy and high-frequency electronics where performance under thermal stress is critical.

Silver Plating Services on Copper Parts

Copper silvering is the preferred solution for applications requiring exceptional electrical and thermal conductivity. Silver coatings also enhance the durability and contact performance of copper components used in power systems, switchgear, and electronic assemblies. Electris guarantees precision and consistent results for every silver-plated copper part.

Silver Plating Services on non-ferrous metal components

Electris offers silver electroplating for non-ferrous metals.. Our silver coatings provide excellent conductivity, corrosion resistance, and antimicrobial properties. Tailored to meet your specific requirements and geometries.

Silver Plating Electrical Components & Machined Parts

We provide precision silver-coated electrical components such as connectors, terminals, contacts, and switchgear parts. The coating ensures excellent conductivity, low contact resistance, and long-term corrosion protection. Ideal for high-performance electrical systems, our silver plating meets industry standards for durability and efficiency.

Silver Plating Methods

There are several methods of applying silver coatings, each selected according to the type of component and its intended application. The most common is electrolytic silver plating, where silver ions are deposited from an electrolytic bath onto a conductive substrate under controlled current. For demanding applications, strike silver plating (a thin initial layer) can be applied to improve adhesion before building up the final thickness. Advanced industries also use selective silver plating, allowing only specific areas (e.g., contact points) to be coated, optimizing both performance and cost. Each method requires precise control of bath composition, current density, and process parameters to achieve a coating with the desired thickness and properties.

Silver Plating Specifications

At Electris, we offer silver coatings on cooper or aluminium alloys, with thicknesses ranging from 1 μm to 50 μm, tailored to customer requirements. Our automated plating line allows the treatment of components up to 2100 mm in length, ensuring both small precision parts and large busbars can be silvered with consistent results. Coating thickness and uniformity are confirmed by laboratory testing in line with international standards. Depending on the specification, silver plating can be optimized for conductivity, corrosion protection, wear resistance, or aesthetic quality. We provide complete documentation and quality control for every batch to guarantee repeatability and compliance with industry expectations.

Industries That Benefit from Silver Plating Services

Silver plating is used across a wide spectrum of industries:

• Power and energy sector – busbars, connectors, and switchgear elements require coatings with high conductivity and oxidation resistance.
• Electronics and telecommunications – silver plating ensures reliable signal transfer in connectors, terminals, and PCB components.
• Automotive and e-mobility – silver-coated contacts and sensors increase reliability in demanding conditions of electric vehicle systems.
• Aerospace and mechanical engineering – sliding components and precision parts benefit from silver’s resistance to friction and high temperatures.

This versatility makes silver plating a key technology for both traditional heavy industry and modern high-tech applications.

Properties of Silver

Silver is a unique metal with a set of properties that make it indispensable in electroplating:

• Highest electrical and thermal conductivity among all metals, ensuring efficient current flow and minimal energy loss. Copper, as a material with excellent conductivity, gains additional properties when coated with a layer of silver – its resistance to oxidation improves and the service life of components used in harsh environmental conditions increases.
• Excellent resistance to corrosion and oxidation, making it suitable for use in aggressive environments.
• Antibacterial effect, which is especially valuable in medical and food industry applications.
• High reflectivity, giving coated parts an attractive, shiny finish, also used in decorative and consumer products.
• Good ductility and adhesion, allowing silver to form durable, crack-free coatings on copper, aluminum, and other non-ferrous substrates.

Thanks to these properties, silver plating is not only a surface treatment but also a performance upgrade that enhances the functionality and reliability of components.
