High-quality electrical pure iron - DT4C AC Relay Iron Core is made of selected material

Electrical pure iron is also known as industrial pure iron. It is a high-quality steel with an iron content of over 99.5%. It is a low-carbon, low-sulfur, and low-phosphorus iron. The DT4C AC Relay Iron Core is made of this type of material and is a key component of the critical element. The concept that needs to be distinguished is:

Pure iron: It is steel with a content of iron close to 100%, a very soft metal.

Pig iron: The carbon content is 3.5% - 5.5%. Industrial pure iron: The chemical composition is mainly iron, with a content of over 99.50%, and the carbon content in iron is less than 0.04%.

Steel: The general term for all iron and iron alloys. The normal carbon content is relatively large. According to the carbon content, it can be divided into high-carbon steel, medium-carbon steel, and low-carbon steel.

From the above, it can be seen that the differences between pure iron, pig iron, and steel mainly lie in the different contents of carbon in iron.

Industrial pure iron is a type of steel. Its chemical composition is mainly iron, with a carbon content of less than 0.04%, and other elements should be as few as possible. Since it is not actually pure iron, this steel that is close to pure iron is called industrial pure iron. This material is also an ideal raw material for preparing the Core Pin. 

There are two common specifications:
One is used as a deep drawing material and can be stamped into extremely complex shapes;

The other is used as an electromagnetic material with high magnetic permeability and low magnetic resistance, and is widely used in electronic and electrical products, electrical components, magnetic materials, amorphous products, relays, sensors, automotive brakes, textile machinery, electricity meters, electromagnetic valves, etc. Among them, the Cold Forging Relay Core is a typical application component. 

Generally, industrial pure iron is extremely soft in texture, has great toughness, and has excellent electromagnetic properties. It meets the strict requirements for soft magnetic characteristics of the Pure Iron Core. The melting point of industrial pure iron is higher than that of iron, and it is less prone to rust in humid air. It can also be passivated in cold concentrated acid.

It has excellent electromagnetic properties. The coercive force (Hc) is low, the magnetic permeability μ is high, the saturation magnetic induction (Bs) is high, and the magnetic property is stable without magnetic aging. This ensures the stable and efficient operation of the Soft Magnetic Iron Cores for Relays.

The purity of the steel is high. The electromagnetic pure iron undergoes refining, so its internal structure is dense, uniform, excellent, and has low gas content. The finished product contains carbon at a maximum of ≤0.004%, which creates reliable conditions for users to simplify and shorten the annealing process of the Pure Iron Relay Core parts.

The cold and hot processing performance is good. Cold processing such as turning, boring, punching, bending, drawing... etc. are all without problems. For hot processing, such as re-melting and re-rolling, the sensitivity to red brittleness is low. Many grades have no red brittleness zone, and can be processed within a wide temperature range, facilitating the forming of the Core Pin.

The surface quality is good. It has good welding and electroplating properties, which can enhance the assembly and protection effect of the Cold Forging Relay Core.

The dimensional accuracy is high. We can provide ultra-precision cold-rolled plates, such as with a plate thickness of ≤1.05mm, the thickness tolerance can be ≤0.03mm; for plates with a thickness of >1.5mm, the thickness tolerance can be ≤±0.05mm, which can meet the precise dimensions requirements of the Pure Iron Core.
