Product Details

Core of electromagnet, or solenoid iron core, or solenoid plunger is the final actuating component of a solenoid. When the coil is energized, the coil will create a magnetic field and the solenoid iron core will move to change a flow path. And when the electricity is off, the magnetic field disappear and the solenoid iron core will become un-magnetic so the solenoid iron core will return to its original position.

Carbon steel is the traditional magnetizable material (except the stainless steel). The higher carton level in the material, the stronger the magnetic field will be. To make solenoid iron core, the most suitable material is soft iron, not steels. When the steels are magnetized, they will keep the magnetic as long as the power is still on.

There are different types of electrical pure iron: pure iron for raw materials (DT1, DT2) and electromagnetic pure iron (DT3, DT4, DT5, and DT6). Pure iron is 99.5% of electrolytic iron, which has the coercive force of Hc=7.2A/m, and the initial magnetic permeability of µi=12*10-4H/m, and the maximum magnetic permeability ofµm=250-4H/m. The higher purity the iron is, the better electromagnetic property it has. But to manufacture high purified iron requires complicated manufacture process which needs higher cost. Normally, the iron manufacturers use electromagnetic pure iron, and during the smelting process, they will add some aluminum-silicon in order to decrease the bad influence of magnetic performance that creates by other impurities. As there is little impurity content in electromagnetic pure iron, it has good cold-working property and high saturation magnetic flux density. But at the same time, the electrical resistivity of electromagnetic pure iron is low, so the iron loss is big, it is most suitable for the constant magnetic field. After the electromagnetic pure iron has been processed, there must be machining residual stress, which lowers the magnetic performance of electromagnetic pure iron, so there must be an annealing process after the machining process.
