What is the difference between electromagnetic pure iron and ordinary iron materials

There are significant differences between electromagnetic pure iron and ordinary iron materials in multiple aspects. The following is a detailed summary of these differences:
1, Definition and Composition
Electromagnetic pure iron: Electromagnetic pure iron is a high-purity steel material, which is a ferritic material containing almost no other impurities except for a small amount of elements such as Fe, C, Si, Al, etc. Its iron content is usually above 99.5%, making it a low-carbon, low sulfur, and low phosphorus iron material.
Ordinary iron materials: Ordinary iron materials contain more impurity elements, such as manganese, silicon, phosphorus, sulfur, etc. The high content of these elements can affect their electromagnetic and mechanical properties.
2, Electromagnetic performance
Electromagnetic pure iron: has excellent characteristics such as low magnetic core loss, low hysteresis, and high magnetic permeability. These characteristics make electromagnetic pure iron widely used in electromagnetic applications, such as power transformers, electromagnetic relays, electromagnetic cores, etc.
Ordinary iron materials: Due to their high content of impurity elements, their electromagnetic properties are relatively poor, with low magnetic permeability, high hysteresis and magnetic core losses, making them unsuitable for applications that require high electromagnetic performance.
3, Processing performance
Electromagnetic pure iron: with a particularly soft texture and high toughness, it is easy to process into various shapes and sizes. Meanwhile, electromagnetic pure iron also has good cold and hot processing performance and can be processed over a wide temperature range.
Ordinary iron materials: Although they also have certain processing properties, their processing difficulty and cost may be relatively high due to the influence of impurity elements.
4, Application Fields
Electromagnetic pure iron: mainly used in the fields of power, electronics, communication, aviation, aerospace, etc., for manufacturing various magnetic components and electromagnetic equipment. For example, electromagnetic pure iron can be used to manufacture power transformers, electromagnetic relays, electromagnetic iron cores, inductors, sensors, etc.
Ordinary iron materials are widely used in fields such as construction, machinery, automobiles, and ships to manufacture various structural components and parts. For example, ordinary iron materials can be used to manufacture steel bars, steel plates, steel pipes, mechanical components, etc.
5, Standards and Testing
Electromagnetic pure iron: China has clear national standards for the purity and magnetic conductivity of electromagnetic pure iron, such as GB/T 6983-2008 "Electromagnetic Pure Iron" and GB/T 13014-2017 "Electromagnetic Pure Iron for Electrical Soft Magnetic Core Materials". These standards specify the various technical indicators and testing methods required for different grades of electromagnetic pure iron.
Ordinary iron materials: There are also corresponding national and industry standards, but their testing indicators are different from electromagnetic pure iron, mainly focusing on their mechanical properties, chemical composition and other indicators.
In summary, there are significant differences between electromagnetic pure iron and ordinary iron materials in terms of definition and composition, electromagnetic properties, processing properties, application fields, standards, and testing. Electromagnetic pure iron has broad application prospects in the field of electromagnetic applications due to its high purity and excellent electromagnetic properties.
