Electrical (electromagnetic) pure iron grades are :DT3, DT3A, DT4, DT4A, DT4E, DT4C, SUYP, SUYB
Deno pure iron chemical composition

Denuo pure iron properties: soft texture, toughness, good ductility, good electromagnetic properties, low coercivity (Hc), high permeability (u), high saturation magnetic sensitivity (Bs), magnetic stability and no magnetic aging, high purity of steel, small red brittleness sensitivity, high stamping and tensile properties.
Product magnetic properties index

Note: B200, B300,... And B10000 respectively means that the magnetic field strength is 2000A/m, 300A /m,... , magnetic induction intensity at 10000A/m.

Deno pure iron appearance: good surface finish, uniform. Such pure iron mainly

Deno pure iron uses: stamping, relays, electromagnetic valves, electromagnetic components made by national defense technology, magnetic shielding equipment, magnetometer, instrumentation, switches, electromagnetic locks, DC motor motors, electrophonics, automotive machine tools electrical appliances, galvanized POTS, magnetic separators, electromagnetic cores, electromagnetic clutches and other electronic industries.

Deno pure ferromagnetic annealing process: The magnetic test sample should be annealed, and the annealing should be protected by vacuum or inert gas, and the decarbonization atmosphere can also be used to prevent the sample from oxidizing, carburizing, rust and other quality changes that affect the accuracy of the test results.

Annealing process: vacuum or inert gas protection annealing, with the furnace temperature to more than 900 heat preservation for 1 hour, after the end of heat preservation with the furnace cooling to below 500 degrees or room temperature out.

Question: Why should the electromagnetic core be made of pure iron?
Answer: The electromagnet is to be able to control the strength of the magnetic field, requiring that there is no magnetic force after the power failure, and the ferromagnetic material without magnetic force will be magnetized in the magnetic field, and there will be residual magnetism after leaving the magnetic field. The residual magnetism of soft iron is basically no, but the steel is very strong, especially the high-carbon steel class, very strong.

Raw material pure iron (charge pure iron) grade is YT0, YT01, high purity of products, excellent indicators, raw material pure iron is known for low carbon, low phosphorus and low sulfur, C content below 0.002, P content below 0.005, S content below 0.004, is your choice to do a variety of smelting. Such pure iron uses: NdFeb industry, stainless steel smelting industry, casting industry, powder alloy, electrical alloy, hard magnetic alloy industry, etc.
