Metal lapel pins with“Black”platings

2024/09/27

Usually we can see some metal lapel pins with black plating, but do you know which kind“black” plating for them?The following introduces four fashionable and popular “Black”platings for metal lapel pins.

 

First,black nickel is normal black plating for metal lapel pins. The black nickel compound is an organic additive that can be incorporated into nickel electrodeposition baths to achieve a black coating on the metal lapel pins in electrolytes. In addition to its excellent anti-corrosion properties, black nickel also enhances the hardness and wear resistance of metal lapel pins.

 

 

Secondly, gun color, because it is similar to the color of the surface of a steel gun,is a tone of iron black that flashes with a cold light. The advantage of gun color for metal lapel pinsis its high hardness, good wear resistance and corrosion resistance, andthe plating color of metal lapel pins is not easy to be oxidized in the atmosphere. The novelty of gun color lies in the fact that different depths of color can be obtained according to the needs, so the plating color of metal lapel pins can range from light black to deep blackdue to the different content of gun color additives. This unique tone has already occupied a place in metal lapel pinscoatings and has been widely used.

 

Thirdly, electrophoretic paint black is a specialized coating technology primarily utilized for treating metal lapel pins surfaces. It involves the movement of charged particles under the influence of electric fields, resulting in the deposition of a protective film on the metal lapel pin surface, which gives rise to the black appearance we observe. The electrophoresis process for metal lapel pins offers several advantages: cost-effectiveness of raw materials, comprehensive and uniform coating, smooth finish, excellent corrosion resistance. Moreover, it is noteworthy that this production process, under qualified exhaust emission facility, generates minimal harmful gas emissions, thereby meeting environmental protection requirements.

Fourthly, the process of anodizing black plating on metal lapel pins involves a specialized electrochemical treatment that results in the formation of a durable oxide layer or other chemical coating on the surface ofmetal lapel pins. This oxide layer exhibits excellent resistance to corrosion, wear, and other desirable properties.However, it is currently limited to applications on metal lapel pinsmade of aluminum.
