Product Features
High Magnetic Permeability
Manufactured from high-purity soft magnetic iron, the forged core offers excellent magnetic permeability, enabling relays to respond quickly and operate efficiently.
Low Coercive Force
Low coercivity allows rapid magnetization and demagnetization, improving relay switching speed and reducing residual magnetism.
Excellent Forging Quality
Hot forging refines the grain structure, resulting in improved density, mechanical strength, and consistent magnetic performance.
Easy Precision Machining
The semi-finished forged core is suitable for CNC machining, turning, milling, grinding, drilling, and other precision operations.
Stable Chemical Composition
Each production batch is carefully controlled to ensure consistent purity and reliable product performance.
Custom Manufacturing
Customized dimensions, tolerances, machining allowance, and heat treatment are available according to customer drawings.

Why Choose Pure Iron for Relay Cores?
Pure iron is one of the most widely used soft magnetic materials for electromagnetic components because it combines excellent magnetic performance with good mechanical properties.
Compared with ordinary carbon steel, high-purity pure iron offers:
Higher magnetic permeability
Lower magnetic losses
Lower residual magnetism
Better magnetic stability
Better machining performance
Longer service life
These advantages help relay manufacturers improve product quality while maintaining consistent production efficiency.
