Pure Iron Relay Core

In modern relay systems, the purity and structural precision of magnetic components directly determine the overall response speed, attraction force, and electrical reliability. Pure Iron Relay Cores, made from high-purity iron, achieve high permeability, low loss, and low remanence through precision forming and heat treatment processes. They are indispensable core magnetic components in new energy and high-end electrical control fields.

Material Advantages

Pure iron, with its unique atomic arrangement and high permeability, is the preferred magnetic material for electromagnetic components.

Compared to silicon steel or iron-nickel alloys, the high-purity iron used by Apollo offers the following significant advantages:

Higher Magnetic Flux Density: Generates a stronger magnetic field under the same excitation conditions, thereby improving relay engagement efficiency.

Extremely Low Residual Magnetism: Effectively avoids the risk of incomplete relay release or delayed engagement.

Excellent Magnetic Permeability Consistency: Grain orientation is controlled through refining processes, ensuring stable longitudinal and radial magnetic permeability.

Excellent Machinability: Suitable for turning, grinding, stamping, and automated assembly processes, ensuring stability in mass production.

Fatigue and Corrosion Resistance: Maintains long-term stable magnetic properties in humid, high-temperature, and vibration environments.
