Raw Material Pure Iron DT1 DT2, Electrical Pure Iron DT3 DT4 DT5 DT6, Electron Tube Pure Iron DT7 DT8 Explanation:

The above pure iron grades are recorded in the metallurgical standard YB200-75. As shown in the figure: ① Pure Iron DT1 and DT2 belong to raw material pure iron, used for smelting, various alloys, Yaoqiang Pure Iron, powder metallurgy, and other high-purity furnace charge applications. They are high-purity iron-based materials with high iron content, low impurities, and clean steel quality. ② Pure Iron DT3, DT4, DT5, and DT6 belong to electromagnetic pure iron, used in magnetic permeability equipment, electronic instruments and meters, sensors, Yaoqiang Pure Iron, and shielding equipment. Their characteristics include low coercivity, high magnetic permeability, and no magnetic aging. ③ Pure Iron DT7 and DT8 belong to electron tube pure iron, used in high-airtightness electron tube components. Their characteristics include no hairline cracks, Yaoqiang Pure Iron, and good airtightness. They are used in aerospace and other fields.
