Bright copper electrolyte - copper electrolyte acidic
Acid copper electrolyte for bright coatings.
Our Betzmann Galvanik bright copper electrolyte convinces by a high deposition rate and a bright copper layer. Subsequent polishing of the polishable copper layer is not necessary. Further characteristics of electroplated copper from our product range are the good levelling properties as well as an excellent scattering. This also applies to the ductility of the product, making the copper electrolyte primarily suitable for thin coatings and multilayer processes.
The bright copper electrolyte has been developed for all electroplating processes from bath plating to pen plating / pad plating. The acidic copper always delivers high quality results regardless of the electroplating process used.
Areas of application of electroplated copper
Electroplated copper plating is often the basis of corrosion protection systems. Here, the copper layer deposited from the copper electrolyte combined with a nickel or chromium coating forms the basic layer of a durable multilayer protection. In combination with brass, copper serves as a functional intermediate layer.
Electroplated copper increases the corrosion resistance of surfaces.
galvanic copper plating improves thermal and electrical conductivity.
Copper-plated surfaces serve aesthetic purposes and are used as design elements in interior design, but also in exterior applications.
Layer build-up in the context of silver plating and gilding of objects.
The very good levelling properties of copper electrolyte reduce the polishing costs of metals. Furthermore, it has a very good polishability.
Gold and silver plating benefit from the layer structure. In this case, bright copper forms the lowest layer, to which a nickel layer is applied before the final gilding or silvering. The nickel layer serves as a diffusion barrier layer, otherwise the copper would diffuse into the gold and turn reddish.
Copper electrolyte for which materials
Alkaline copper electrolyte and copper acid are suitable for a variety of different materials. However, please differentiate precisely between acid-sensitive and acid-resistant materials. Acid-resistant materials such as nickel, copper, brass or bronze can be electroplated with copper acidic in the first step. Acid-sensitive materials such as zinc or iron require pretreatment with alkaline copper electrolyte. Only then is galvanic copper plating with bright copper electrolyte in the form of copper acidic possible.
Surfaces of aluminum, chrome, zinc, tin or titanium are unsuitable for direct acid copper plating.
How to achieve optimum results
You use the high-quality bright copper for bath plating and pen plating / pad plating. It provides optimum results in every process, provided that the following parameters are taken into account:
Bath electroplating: 0.3-2V (approx. 0.8-1.2V recommended at 10cm distance).
pin electroplating: 1,2-4,5V (approx. 3V recommended)
Current density: 0.6-4.2A/dm² (up to 7A/dm² with bath movement)
Working temperature: 15-60°C
deposition rate: approx.1.5µm/min at 3A/dm² and 20°C
Use graphite or copper anodes as anodes.
Correct application for high-quality results
Prior to electroplating, whether bath or pen plating, clean the workpiece with utmost care, e.g. by thoroughly degreasing it with alcohol. Use disposable gloves to avoid transferring skin grease to the surfaces. Contamination caused by rust must be completely removed. In case of pen plating, make sure that the tampon is always in motion.
You can either heat the bright copper to the recommended temperatures or use the electrolytic copper at room temperature.
Copper plating should only be carried out in well-ventilated rooms and the vapours and aerosols produced should not be inhaled.
