Pure iron refers to industrial-grade pure iron, which has an iron content of 99.8% to 99.9%. The remainder consists of
several impurity elements, such as C, Si, Mn, S, and P, among which the carbon content accounts for approximately 0.00
08% to 0.0218%. Its melting point is 1538°C; iron with zero carbon content is referred to as
pure iron.

At room temperature, pure iron is a ferromagnetic metal; at temperatures above 770°C, it transforms into a non-ferromagnetic metal.
This transition temperature is also known as the Curie point.

The plasticity of pure iron decreases as the carbon content increases. Industrial pure iron with a carbon content (mass fraction) of 0.02%
still possesses good cold and hot working plasticity and can be cold-rolled into thin sheets, strips,
and Electrical-Grade Pure Iron Round Bar (High-Purity Electromagnetic Iron) is primarily used in DC/low-frequency electromagnetic components, precision magnetic circuits, magnetic shielding, and scientific research and military applications. It achieves efficient magnetic conductivity and precise magnetic control through its extremely high magnetic permeability, extremely low coercivity, and absence of magnetic aging.

I. Core Electrical/Electromagnetic Components (Most Common Applications)
Relays, contactors, solenoid valves: Used for cores, armatures, and yokes to enable small-current control of large currents or pneumatic circuits, featuring fast response times and extremely low residual magnetism.
DC Motors / Generators: Stator and rotor cores, as well as housings, providing stable, strong magnetic fields.
Electromagnets, magnetic chucks, clutches, and brakes: Used in machine tools, lifting equipment, and automation systems, featuring strong holding force and complete demagnetization.
Inductors and transformers (low-frequency / DC): Enhance magnetic efficiency and reduce losses.

II. Precision Instruments and Sensors
Analytical / Measurement Instruments: High-resolution magnet pole pieces, electromagnetic separators, detectors, and meter cores.
Electron Microscopes / Accelerators: Focusing magnets, electromagnetic lenses, and bending / focusing magnets for high-energy accelerators.
Sensors, Magnetic Switches: Enhance sensitivity and stability.

III. Magnetic Shielding (Critical Applications)
Manufacturing magnetic shielding enclosures/boxes to protect precision electronics, instruments, and chips from external magnetic field interference.

IV. Defense and Aerospace
Aircraft autopilot components, aviation instruments, magnetic circuit parts for radar/communication equipment, and precision electromagnetic components for defense applications.

V. Other Industrial and Special Applications
Magnetic separators, magnetizers: pole pieces, cores.
Electroacoustic devices: Magnetic circuit components for loudspeakers.
Vacuum / Electron tube components: High-purity, low outgassing, no magnetic aging.
Research / Laboratory: Standard magnets, experimental cores, high-purity material substrates.

VI. Key Characteristics (Supporting Applications)
Exceptional soft magnetic properties: High magnetic permeability, low coercivity, high saturation flux density, no magnetic aging.
Excellent Machinability: Easily machined, stamped, welded, and plated; high dimensional accuracy.
Limitations: Low resistivity and high AC eddy current losses; primarily used in DC and low-frequency INCLUDE:
