Sintered NdFeB magnets are widely used in all walks of life in the current era of rapid development. NdFeB is easy to oxidize and needs a protective layer, which is called electroplating and surface treatment. Because the elements nd and Fe in NdFeB permanent magnets are easy to corrode and oxidize, the corrosion resistance and oxidation resistance of sintered NdFeB permanent magnets are poor, Therefore, how to improve its anti-oxidation and corrosion performance and do a good job in its surface protection has become an important problem in production and use. The commonly used coatings are zinc, nickel, copper, nickel, black nickel, gold, silver and epoxy resin, but the most commonly used coatings are zinc plating and nickel plating, copper and nickel plating.
What is the difference between galvanized and nickel plated copper nickel neodymium iron boron magnets?
1. Polishing difference between galvanized and nickel plated copper nickel: because the polishing of nickel plated copper nickel is superior to zinc, it is brighter in appearance.
2. The difference of antirust ability between zinc plating and nickel plating copper nickel: zinc plating is general, nickel plating copper nickel is good, and chromium plating is the best.
The electroplating method is mainly determined by the environment used by the magnet. If the environmental conditions are high, it is recommended to use nickel, copper and nickel. The price of nickel, copper and nickel is more expensive than that of zinc, and zinc is also superior to nickel, copper and nickel in price.
3. Performance difference between zinc plating and nickel plating copper nickel: after the treatment of nickel copper nickel surface, the temperature resistance is also improved a lot, coupled with the conductive characteristics of nickel copper nickel itself.
4. The hardness difference between zinc plating, nickel plating, copper and nickel: it is also high. In general use, it can greatly avoid collision and make the corner fall.
5. Price difference between zinc plating, nickel plating, copper nickel: zinc has advantages. The price from low to high is zinc plating, nickel plating, copper nickel and chromium plating. The difference between materials and labor determines the price. Conventional zinc, nickel, copper and nickel are barrel plating and chromium is hanging plating. Nickel copper nickel: a method of plating a layer of nickel on metal or some non-metal by electrolytic or chemical methods, which is called nickel copper nickel.
The above is the difference between zinc plating, nickel plating, copper and nickel,
In real life, we encounter more zinc plating, which means that a layer of zinc is plated on the surface of metal, alloy or other materials, with a silver appearance. It can ensure that the product can avoid deformation under various living substances and natural environment, which is also the main reason for its wide application.
