Electromagnet material knowledge

The metal inside the electromagnet includes shell, iron core, moving iron core, nuts, copper washers, copper tubes, blocks and other metal parts. After the metal parts are processed and formed, they need to undergo special surface treatment to ensure the wear resistance and anti-wear of the product. To reduce rust and improve product life and performance, let’s analyze the types and processing techniques of surface treatment of electromagnet accessories.
1. The electromagnet shell is generally made of SPCC cold-rolled plate. This material has superior magnetic permeability, low manufacturing and processing costs, and is the most widely used in the market. The electroplating processes used are generally galvanizing, electrophoresis and hard chromium plating. . Depending on the different needs of customers, galvanizing is generally blue zinc, which is environmentally friendly and affordable. Electrophoresis has a beautiful appearance, better corrosion resistance, and higher cost. The appearance of chrome plating is not that bright, but it has good corrosion resistance and the product has good scratch resistance! The price is on the high side.
2. The electromagnet core is generally made of easy-turn iron, but a few use pure iron and S10C materials. Electroplating is used respectively: zinc plating, low cost, not wear-resistant; hard chromium plating, moderate cost, poor appearance; nickel plating, more commonly used, moderate cost, the corrosion resistance and service life of the product are relatively recognized by the market. There are also Teflon plating and zinc-nickel alloy plating. The cost is higher, but the appearance and corrosion resistance of the product are the best.
3. Copper tubes. The surface of the original copper tubes is rough and the friction will be large when the electromagnet is working, which will affect the product life, so the copper tubes will be treated with Teflon. Guarantee product life and performance.
