Products Description
The Relay Steel Yoke employs a pure iron substrate magnetic structure design, featuring high permeability and low coercivity, effectively reducing magnetic circuit losses and improving the response speed of the relay's engagement and disengagement. The copper plating layer thickness is consistently controlled at 3-5μm, combining conductivity and oxidation resistance to reduce contact resistance and prevent oxidation corrosion during long-term operation. Precision stamping ensures dimensional tolerances within ±0.02mm, guaranteeing assembly accuracy with the coil frame and contact components and reducing magnetic circuit gaps. The integrated molding structure has no additional welding points, resulting in uniform stress distribution and the ability to withstand alternating stresses generated by repeated switching of the electromagnetic coil, preventing fatigue fracture.

Product Features and Functions
Excellent Magnetic Permeability
The Relay Yoke Stamping uses high-purity iron as its base material, resulting in high magnetic saturation density. It can quickly establish a stable magnetic field under rated operating current, improving electromagnetic conversion efficiency.
Reliable Copper Plating Protection
A uniform 3-5μm copper plating layer provides complete coverage, free of pinholes and plating defects. This isolates the base material from air and moisture, extending the service life of the Pure Iron Relay Yoke Plate under complex operating conditions.
Strong Structural Adaptability
Standardized mounting slots and positioning holes allow direct matching with most relay coil frames, enabling assembly without additional processing and reducing assembly errors.
Optimized Heat Dissipation Path
The Sheet Metal Relay Yoke utilizes a stamped, one-piece structure, allowing heat to be quickly conducted to the outer casing through the copper layer and base material, preventing localized overheating during coil operation.

Manufacturing Process and Types Summary
Stamping-Blanking Compound Die and Bending Process
Suitable for mass production of standardized Power Precision Relay Yoke Stamping Parts. Low single-process die cost, flexible production changeover, suitable for switching between multiple product types and small batches.
