Why Use Copper Plating?

Copper plating is the process of plating a layer of copper electrolytically on the surface of an item. It is one of the most widely used metal finishes in a range of industries from electronics and telecommunications to automotive and aerospace. The reasons are largely due to the unique characteristics of copper.

Conductivity

One of the main benefits of copper plating is its ability to improve the conductivity of the object that undergoes the copper plating service. Outdone only by silver, copper stands as the second most conductive metal there is, which means that copper can carry more electrical current than other metals. And the coating of copper plating will be helpful in areas where high electrical conductivity is required, such as electronic parts and components used in automobiles, aircraft, spacecraft, and so on.

Malleability

Copper is a soft metal and copper plating is inherently very flexible, so it can be formed and stretched into complex and intricate surfaces without breaking, and also will not peel out when the material is subjected to stress - making it possible to create spires, steeples, musical instruments, bowls, bed frames, tubes and a huge number of other useful and beautiful products.

Heat Treatment

Copper plating results in a high thickness build and can serve as a heat-treatment stop-off for selective heat treating. Copper coatings can even act as a type of lubricant in high-temperature conditions.

Adhesion

Copper creates a smooth and even protective layer on ferrous and non-ferrous metals during the electroplating process. This coverage provides a reliable undercoat for additional plating finishes or top-coats. This means copper plated components are able to benefit from the dual characteristics of copper and the additional processes that are layered on top of the plating. Meanwhile, because copper is highly adhesive, it won’t separate from the material even when the object is being bent or shaped.

Corrosion Resistance

Like many electroplating processes, copper plating increases the corrosion resistance of the material. While copper is not the most corrosion-resistant metal available, when added to the substrate in combination with another highly corrosion-resistant metal like nickel, it results in a combination that can withstand an extremely corrosive environment. Copper is also used to fill surface imperfections in base metals, which results in smooth, level surfaces that readily accept soldering or coverage with other coatings or platings.

Antibacterial Properties

Copper can inhibit the growth of a variety of different microorganisms, highlighting yet another benefit of copper plating – it naturally kills bacteria. This fantastic property means that a copper finish is widely used to coat laboratory and medical equipment.

Money Saving

Copper is less expensive and more readily available than noble metals such as platinum, gold and silver, for it can be found in abundance. Meanwhile, this material can yield consistent component quality with a minimum of production challenges.

Without copper as an option, we may find ways to handle electroplating to achieve what we need, but copper makes the finished product less expensive and more versatile. The benefits of copper in electroplating make the metal very worthwhile.

We will provide you high-quality water bottle with copper plating layer. On the one hand, the copper plating on the exterior of the inner wall enhances the insulation effect by 30% - it forms a heat-insulating layer that reflects heat and significantly reduces heat loss. On the other hand, our water bottle that is insulated with a copper wall layer helps to eliminate condensation by providing an exterior that won't sweat on your hands or in your bag. This kind of bottle performs better than regular vacuum insulated stainless steel bottles
