What is Gun-Colored Tin-Nickel Gun? What does it mean in electroplating?
Publish Time: 2024-06-07
Gun-colored tin-nickel gun is a specific term used in the electroplating process. It actually refers to a coating with a specific color tone obtained by electroplating tin-nickel alloy or tin-cobalt alloy. In the electroplating process, gun-colored tin-nickel gun specifically refers to the following two aspects:
Material and composition:
The gun-colored tin-nickel gun coating is composed of tin-nickel alloy or tin-cobalt alloy. This alloy is formed on a metal substrate through an electroplating process and has unique color and physical properties.
The gun-colored tin-nickel alloy has high hardness and wear resistance, and is suitable for application scenarios such as pen barrels or door locks that require wear resistance.
Tone and characteristics:
The gun color is called rifle color in Japan, gun black in Europe and the United States, and is referred to as gun color in my country. This color tone has no exact color definition. From light black to dark black, it is called gun color and has a metallic luster.
The gun color coating has a soft color, ranging from light gray to gray-black, and the color is uncertain, which is more dynamic and vibrant than the clear appearance.
In addition to the elegant color tone, the gun color coating also has the advantages of high hardness, good wear resistance, and strong corrosion resistance. It is not easy to change color in the atmosphere and is suitable for electroplating of workpieces with complex shapes.
Electroplating process:
The key to electroplating gun color is gun color additives, such as sulfur-containing amino acids such as methionine or cystine. Different contents of these additives will cause different blackness of the gun color coating.
During the gun color electroplating process, because the coating is extremely thin and translucent, the light penetration and zigzag reflection will produce a flashing cold atmosphere. Therefore, the thickness of the gun color coating should generally not exceed 5μm to maintain its unique visual effect.
Application field:
Gun-Colored Tin-Nickel Gun coating is widely used in various fields such as jewelry, automobiles, clocks and watches, lighting, architectural decoration, daily hardware, clothing accessories, etc. due to its unique color tone and physical properties.
Gun-Colored Tin-Nickel Gun is a coating with specific color tone and physical properties obtained by electroplating tin-nickel alloy or tin-cobalt alloy. In the electroplating process, it is valued for its unique color tone, excellent physical properties and wide application fields.
