Armature For Electromagnetic EV Relay
Products Description
In new energy electric vehicle systems, high-voltage DC relays and contactors undertake the core tasks of circuit switching and safety control. The Armature for Electromagnetic EV Relay, as a key moving or static magnetic component in the electromagnetic system, directly affects the reliability of the entire relay system.
This product is made of high-purity electrical pure iron material, manufactured through precision stamping and optimized structural design. It is widely used in:
Electromagnetic relay armature
Magnetic circuit yoke core
High-voltage DC contactor metal casing
Key structural components of magnetic latching relays
Its core value lies in: constructing a highly efficient, low-loss, and fast-response magnetic circuit system.
Material Advantages
For dynamically moving components, material selection is a more complex game. While ordinary electrical pure iron boasts excellent magnetic permeability, its excessive softness makes it highly susceptible to microscopic plastic deformation (work hardening) at stress points after tens of thousands of high-speed impacts. This alters the air gap in the magnetic circuit, ultimately causing relay failure.
Our material advantage lies in the introduction of the concept of "micro-alloyed modified electrical pure iron." By maintaining an extremely low carbon content and precisely controlling minute amounts of specific alloying elements (such as trace amounts of aluminum and silicon), we significantly improve the material's yield strength and fatigue limit without increasing coercivity (or sacrificing magnetic permeability). The advantage of this material formulation is that it gives the Relay Armature Soft Magnetic Iron a "robust skeleton," allowing it to maintain its initial flatness and dimensional stability even after withstanding high-speed mechanical impacts (up to hundreds of Gs of instantaneous acceleration) during armature-yoke engagement. This fundamentally solves the problem of magnetic performance degradation caused by dynamic wear.
Manufacturing Process Highlights
Precision Progressive Die Design
The die employs an interlocking structure, with carbide inserts used at wear-prone stations, ensuring a lifespan of millions of strokes. Integrated misfeed detection and sensors within the die ensure continuous production stability.
Vacuum or All-Hydrogen Annealing Furnace
The annealing furnace offers high temperature uniformity and a low dew point protective atmosphere, preventing oxidation and carbonization. Each furnace includes a sample for magnetic property testing.
Automated Post-Processing Line
After annealing, the Armature Metal Parts of Relays enter an automated deburring, cleaning, surface treatment, drying, and packaging line. The entire line operates in a closed system, minimizing contamination and damage from human contact.
Optical Imaging Inspection
Online optical inspection is performed on critical dimensions (total length, width, thickness, hole positions, and flatness of the mating surface), automatically rejecting defective armatures in relays. Inspection data is uploaded to a database in real time, enabling batch quality traceability.

Surface Finish
The stamped surface is smooth with an extremely low proportion of tear bands, effectively reducing assembly stress during installation.
Consistent Electroplating Process
Special barrel plating or rack plating techniques ensure uniform coating (such as environmentally friendly zinc, nickel, or silver) without the risk of hydrogen embrittlement, maintaining long-term chemical stability.
Precision Packaging
Rust-proof bags and custom blister trays prevent collisions, deformation, or moisture damage during international sea transport for Electrician Pure Iron Armature.
