A Guide to Electroplating with Yongrad: Applications, Coating Thicknesses and Industry Use
Yongrad is a leading supplier of custom electroplating plants and high-performance equipment for industries that rely on metal coatings to improve durability, electrical conductivity and corrosion resistance. This guide sets out the various types of electroplating, their applications by industry, the optimum coating thicknesses and how each sector uses these coatings for better performance and longer life.
Copper Plating
Applications: Copper plating is valued for its exceptional electrical conductivity, heat dissipation and adhesion. As a base layer, copper improves the bond for subsequent plating layers, raising overall durability and performance.
- Coating Thickness: Usually 2 to 10 microns for conductivity; thicker layers, up to 100 microns, add durability and heat management.
- Industry Use:
- Electronics: Essential for printed circuit boards, connectors and cabling, where conductivity and performance must be excellent.
- Automotive: Applied to radiators, heat exchangers and other components that need efficient heat transfer and corrosion resistance.
- Plumbing: Used on pipe and fittings to prevent corrosion in humid conditions, in both domestic and industrial systems.
Zinc Plating
Applications: Zinc plating forms a protective layer that keeps parts from rusting, and is particularly effective where they meet moisture, salt or harsh chemicals. Alloyed with nickel, zinc resists wear better still in difficult conditions.
- Coating Thickness: Usually applied between 5 and 25 microns; for heavy-duty use, layers may reach 50 microns.
- Industry Use:
- Automotive: Used on fasteners, bolts and frames exposed to road salt, moisture and temperature swings, preserving structural integrity.
- Construction: Applied to screws, nails and other hardware to protect against corrosion outdoors.
- Aerospace: Applied to landing gear, brackets and structural components, protecting against corrosion while preserving the light weight that aircraft performance depends on.
Tin Plating
Applications: Tin plating is known for its resistance to oxidation and its excellent solderability, which makes it ideal both for electronics and for food-safe containers. It gives a smooth, durable surface for safe, effective use.
- Coating Thickness: Usually 0.5 to 15 microns; thin layers suit electronic connections, thicker coatings are used on food containers.
- Industry Use:
- Electronics: Widely used for connectors, terminals and contacts because it solders so readily.
- Food and Beverage: Applied to food containers and cans as a non-toxic, corrosion-resistant barrier.
- Medical Devices: Gives small medical components reliability in sterilised environments without introducing toxicity.
Nickel Plating
Applications: Known for hardness, wear resistance and even coverage on complex parts, nickel plating is essential in high-stress environments. Electroless nickel gives a consistent layer even over intricate surfaces.
- Coating Thickness: Usually 2 to 25 microns, rising to 100 microns for heavy-duty requirements.
- Industry Use:
- Aerospace: Protects turbine blades, gears and engine parts against wear and high temperatures.
- Medical Devices: Improves the durability of surgical instruments and their resistance to repeated sterilisation.
- Oil and Gas: Improves the corrosion resistance of valves, pumps and drilling equipment in hard conditions.
Gold Plating
Applications: With excellent conductivity, corrosion resistance and a luxurious appearance, gold plating is ideal for high-precision applications where longevity and reliability matter most.
- Coating Thickness: 0.5 to 3 microns for electronics; decorative applications may call for up to 5 microns.
- Industry Use:
- Electronics: Widely used on connectors, semiconductors and precision components that require dependable conductivity.
- Jewellery: Gives a luxurious, tarnish-resistant finish that improves both appearance and durability.
- Medical Implants: Biocompatible coatings for pacemakers, dental implants and other devices exposed to body fluids.
Silver Plating
Applications: Silver offers excellent electrical and thermal conductivity, making it a cost-effective alternative to gold. Its tarnish resistance and malleability are an advantage in high-performance parts.
- Coating Thickness: Usually 0.5 to 10 microns; high-stress environments may need thicker layers.
- Industry Use:
- Telecommunications: Gives connectors and contacts high conductivity and reduces signal loss.
- Aerospace: Used where thermal conductivity and light weight are critical, such as wiring and relays.
- Food Service: Popular for cutlery and serving dishes for its appearance and its resistance to tarnish.
Palladium Plating
Applications: Palladium gives corrosion resistance and a hard, bright surface, a cost-effective alternative to gold for low-maintenance, durable applications.
- Coating Thickness: Usually 0.1 to 5 microns; industrial applications may require thicker coatings for greater durability.
- Industry Use:
- Electronics: A cost-effective solution for connectors, switches and components that must stay reliable for years.
- Automotive: Provides heat resistance in sensors, spark plugs and catalytic converters.
- Dental Instruments: Gives medical instruments biocompatibility and corrosion resistance.
