US imports of pure iron DT4A cutting iron bars DT4A pure electric iron: for electromagnetic relays, iron with iron, soft iron, magnetic clutch with iron, electronic locks with iron, automotive piston with electric iron magnetic tape with iron, aviation instrumentation, military iron, galvanized iron pot with a plate, iron plate with electronic components, solenoid valves, magnetic separator with iron, no hairline iron, electronic effective iron, easy turning electric iron electric iron Application: 1 Uses: mainly used for electrical, telecommunications, instrumentation and international cutting-edge industries making solenoid electromagnet cores. 2 main features: 1) good electromagnetic properties. The coercive force (Hc) of low magnetic permeability μ is high, the saturation magnetic induction (Bs) of high magnetic stability nor the magnetic aging. 2) high purity steel. Electromagnetic iron series of steel are killed steel, has adopted the refined, so the internal organization of dense, uniform, fine, less gas content, finished carbon content ≤0.004%, which created conditions for reliable parts users to simplify and shorten the annealing process . 3) Cold, thermal processing performance. Cold, such as cars, pier, red, bend, pull ...... so no problem. Thermal processing, such as re-forging, re-rolling process, crisp red sensitivity is small, many grades no red brittle zone, to ensure processing in a wide temperature range. 4) good surface quality. Good welding and plating performance. 5) high dimensional accuracy. Provides ultra-precision cold-rolled sheet, such as the thickness ≤105mm, thickness tolerance can ensure ≤0.03mm; thickness of 1.5mm, the thickness tolerance can ensure ≤ ± 0.05mm.
