Model Description
Types of electroplating nickel plating processes
Types of crafts | Process characteristics | Applicable materials | The main benefits of nickel plating |
Ordinary nickel plating | Silvery white, matte, fine crystals, no brightener, low internal stress | Metal substrates such as steel, copper and copper alloys, aluminum and aluminum alloys (need zinc pretreatment), and magnesium alloys | Suitable for basic protection of structural parts. |
Bright Nickel Plating | Contains organic brighteners (such as saccharin, butynediol), the coating has a mirror-like luster and does not require subsequent polishing | Steel, copper alloy, zinc alloy (needs pre-plating or passivation), plastic (after chemical plating pre-treatment) | The corrosion resistance is better than dark nickel, suitable for decorative parts (such as bathroom hardware, electronic product housing) |
High Stress Nickel Plating | High internal stress, extremely high hardness (300-500HV), excellent wear resistance, but poor ductility | Mainly suitable for steel substrates (such as tools, molds, bearings) | Significantly improve surface wear resistance and extend the service life of moving parts (gears, mold edges) |
Low Stress Nickel Plating | Contains stress relief agent, low internal stress, good ductility, suitable for thick coating deposition | Steel, copper alloy, etc., especially suitable for substrates requiring thick coatings (such as repair of worn parts) | The coating is not easy to crack and is suitable for parts that need to be bent or deformed |
Chemical Nickel Plating | No external power supply is required, nickel-phosphorus alloy is deposited through chemical reaction, and the coating uniformity is excellent (suitable for complex shapes) | Metals (steel, copper, aluminum, etc.), non-metals (plastics, ceramics, glass, etc., which require activation pretreatment) | Excellent corrosion resistance and wear resistance, suitable for chemical equipment and seals; |
Satin Nickel Plating | Matt or satin appearance, no mirror gloss, soft texture, contains special matte additives | Steel, copper alloy, etc., especially suitable for substrates requiring thick coatings (such as repair of worn parts) | Enhance the quality of high-end decorative parts (luxury accessories, instrument panels); avoid mirror reflections and are suitable for light-sensitive scenes. |
Black Nickel Plating | Black appearance, composed of compounds of nickel, sulfur, selenium and other elements, has both decorative and matte properties | Steel, copper alloy, zinc alloy (need to be pre-nickel plated） | Used in functional scenarios such as optical instruments (matte), weapon parts (camouflage), etc. |

Factory Service Highlights
We have a professional chemical nickel plating workshop that can process large non-standard parts with a maximum size of 2m×1m×0.8m and micro non-standard parts with a minimum size of 0.5mm.
The factory has its own laboratory, which can optimize the plating solution formula according to the use environment of non-standard parts (such as high temperature, high humidity, acid and alkaline media).
Applicable non-standard parts: aerospace special-shaped connectors, petroleum machinery deep hole components, electronic communication precision non-standard parts, chemical equipment corrosion-resistant accessories, etc.
We are a physical factory specializing in surface treatment of non-standard parts
With over 20 sets of professional electroplating equipment and a 15-person technical team, we offer a comprehensive service process, from process selection and sample testing to mass production, tailored to your specific part material (metal/some engineering plastics), application scenario, and performance requirements. We support processing based on supplied samples and custom drawings, rejecting the compromises of "standardized production" to ensure each custom part receives a precisely tailored surface treatment.
