Surface treatment (coating)
Neodymium magnet coating: nickel, copper, chromium, gold, black zinc, epoxy resin. The surface electroplating process is different, with different colors and storage time periods, each with its own advantages and defects.
1. Galvanization
The surface appears silver white and can withstand corrosion for 12 to 48 hours. It can be used for bonding with certain adhesives (such as AB adhesive). If the electroplating process is good, it can be stored for about two to five years. Its main advantage is that the price is relatively low.
2. Nickel plating
It looks stainless steel in color, and when left in the air, the surface layer is not easily oxidized by the air. It has a beautiful appearance and good brightness, and the electroplating process can withstand 12 to 72 hours of salt spray testing. Its main drawback is that it cannot be bonded with certain adhesives, as it may cause the coating to peel off. Accelerated air oxidation, currently the nickel copper nickel electroplating process is commonly used in the market for 120 to 200 hours, but its electroplating process cost is relatively high.
3. Copper plating
It often appears in the hardware and building materials industry, and black anti-static tweezers are rarely used in the field, with a yellow appearance.
4. Chromium plating
The field of chromium electroplating is also relatively rare, and its electroplating process cost is high, which is generally unacceptable to companies. But its anti-corrosion ability is strong and it is difficult to react with other substances. The key lies in areas with strong acidity and alkalinity, and the prices of domestic products are relatively low, so there are very few people choosing.
5. Black zinc plating
According to customer requirements, the surface of their products is treated to black. In terms of electroplating process, it is mainly necessary to undergo chemical treatment and add a layer of black protective film on the premise of galvanizing. This film can also have the function of maintaining the product, increasing the duration of salt spray testing, and extending the duration of air oxidation. But its surface is very easily scratched, losing its protective effect. Nowadays, there are very few people using it, and most of them are replaced by epoxy resin.
6. Plating
This field is now very popular, and some of the yellow gold jewelry we see on the street is mostly plated with gold or copper. Gold plating makes the appearance of the product look like gold, very attractive, and is usually suitable for the jewelry field. Magnetic stone products can also be gold plated for magnetic jewelry.
7. Epoxy resin plating
After nickel plating, apply a layer of resin paint on the outside. This manufacturing industry has only had a market in the past two years. Its development trend is fast. Nowadays, more and more people are using various electroplating products. Its biggest advantage is that it can achieve the desired appearance color.
