Hengdian Dongyang City, Kim Dae-magnetic Factory --- Tips Tips You magnet after plating naked eye can not distinguish :: magnet magnetic and high and low temperature. Zinc, nickel-copper and nickel are relatively common and cost-effective good plating. Galvanized price is slightly cheaper, there are environmental white zinc, color zinc. White zinc stable and durable, more common. Nickel-plated copper-nickel price is slightly expensive, but better rust. Hengdian Kim --- NdFeB magnetic plant (Sintered NdFeB) sintered NdFeB permanent magnets after grinding powder airflow smelt, NdFeB wholesale coercivity value is high, and has a high magnetic properties, Shandong NdFeB, its maximum energy product (BHmax) higher than the ferrite (Ferrite) more than 10 times. Mechanical properties of its own is also very good, can cutting different shapes and drilling. The maximum operating temperature of up to 200 degrees Celsius performance products. Since the material content easily lead to rust, NdFeB manufacturers address, so the need for surface coating of different according to different requirements. (Such as zinc, nickel, zinc and environmental protection, environmental protection, nickel, nickel-copper-nickel, nickel-copper-nickel environmental protection, etc.). Very hard and brittle, have high resistance to demagnetization, high cost / performance ratio, does not apply to high operating temperatures (> 200 ℃). NdFeB manufacturers | Shandong NdFeB | Kim large magnetic plant is provided by a large magnetic Hengdian gold plant. Hengdian Dongyang City, Kim Dae-magnetic Factory (www.jjdct.cn) strong, credible, Zhejiang Jinhua electronics, electrical products manufacturing equipment industry has accumulated a large number of loyal customers. The company better work attitude and constantly improving innovative ideas will lead Kim Dae-magnetic plant into the brilliant and you work for a better future!
