Tin Nickel Alloy Plating

Electroplating nickel-tin alloy has many advantages: strong corrosion resistance and good brightness. Electroplating nickel-tin alloy is mainly composed of a variety of metal alloys, also known as nickel-tin electroplating. The electrolyte used is generally an acid solution of tin sulfate or an alkaline solution of tin sulfamate. Advantages of electroplating nickel-tin alloy: 1. Good corrosion resistance and high temperature resistance. The nickel-tin alloy plated on the surface of the electroplated part has certain corrosion resistance, and can resist high temperature up to 300℃. 2. Strong and wear-resistant, impact-resistant and wear-resistant. After nickel-tin alloy coating, the surface wear resistance and fatigue resistance of the electroplated part can be improved, and its mechanical properties can be improved. 3. Good brightness and strong decorative effect. The electroplating of nickel-tin alloy has a silvery white color, and the brightness above is excellent. After nickel-tin alloy electroplating, the electroplated part appears as a bright and beautiful luster, which has a very good decorative effect. 4. High solderability, will not produce oxidation for long-term storage. Nickel-tin alloy plated on the surface of the electroplated part has good solderability, and can maintain solderability for a long time without oxidation or blackening, making it ideal for long-term storage. In the electroplating process, attention should be paid to the concentration of the solution, the temperature of the solution, and the current density as well as other parameters, so as to ensure good quality of the electroplated nickel-tin alloy layer. The thickness of the plated layer is generally maintained within 0.1um-0.3um. After electroplating, the surface of the electroplated parts must be tested, and those unqualified parts should be re-polished and electroplated. The quality of the nickel-tin alloy electroplating not only determines the performance and service life of the electroplated parts, but also has a certain relationship with the chemical reaction and structure of the material, and its quality also determines the quality and service life of the electroplated parts. Through the above introduction, we know that in the process of electroplating nickel-tin alloy, it is necessary to pay attention to many aspects, such as the concentration of the solution, the temperature of the solution, the current density, etc., so as to ensure the good quality of the plated coating. In order to get the ideal plating effect for the nickel-tin alloy electroplated parts, we must ensure that the conditions of our electroplating solution are favorable and controllable, so as to ensure excellent quality of the plated coatings.
