Products Description
As the heart of the magnetic circuit in industrial control relays, the DT4C AC relay iron core dictates how dependable, fast, and long-lived the relay will be. Built specifically for alternating-current relays, it is machined from high-purity DT4C pure iron, then shaped by precision stamping, stress-relief heat treatment, and copper-tipped riveting. The result is a core that offers ultra-high permeability, exceptionally low coercive force, and minimal iron losses-perfect for efficient electromagnetic energy conversion. From factory automation and power-switching gear to motor protection, traffic lights, and household appliances, this core helps relay makers deliver higher performance and a clear competitive edge.
Product Features and Functions
| Stable Magnetic Performance | The Grooved Core for AC Relay undergoes vacuum annealing, resulting in uniform grain size and low hysteresis loss. It maintains stable permeability over a wide temperature range, ensuring consistent relay operation even in extreme environments. |
| Synergistic Enhancement with Copper Components | The matching copper rings and terminals not only provide conductivity and fixation but also optimize the magnetic circuit distribution through eddy current effects, reducing core heating. This makes it particularly suitable for high-load applications such as the Iron Core Relay Part. |
| High Structural Reliability | The AC Core Riveted with Copper Terminal utilizes a cold-press riveting process, resulting in excellent bonding strength between the core and copper components. Its vibration and shock resistance meet industry standards and can withstand high-frequency switching cycles without loosening. |
| Environmentally Compliant | The Pure Iron Core for AC Relay product complies with RoHS and REACH environmental directives. It has no harmful coatings, and all raw materials have undergone professional testing, making it suitable for direct application in fields with stringent environmental requirements, such as new energy and medical equipment. |
Metal Forming Process
Precision Forming of Pure Iron Core
Using DT4C pure iron coils, formed through stamping and cold extrusion, the Grooved Core for AC Relay exhibits precise tolerance control. Subsequent vacuum annealing eliminates internal stress, ensuring uniform and stable magnetic properties.
Copper Part Machining and Surface Treatment
The copper terminals and copper rings of the Relay Core are precision stamped and CNC turned. The surface is tin-plated, improving conductivity and preventing oxidation. The mating surfaces with the iron core are smooth and flat, ensuring structural precision after riveting.
Cold Press Riveting Composite Process
Specialized equipment is used to achieve cold-pressing bonding of the iron core and copper parts, eliminating the need for welding or bonding. This avoids the impact of hot working on magnetic properties, and the resulting metal interlocking structure exhibits excellent fatigue resistance.
Finished Product Inspection and Sorting
Each batch of Iron Core Relay Part products undergoes magnetic permeability testing, pressure resistance testing, and salt spray testing. Professional equipment is used for full-dimensional inspection to ensure consistent quality. Sorting and labeling services can be provided according to customer needs.
Packaging and Transportation
Packaging Solution: Anti-static plastic bags + cardboard boxes are used for packaging. Each box includes a moisture-proof desiccant and shock-absorbing foam to ensure the AC Core Riveted with Copper Terminal product is not damaged during transportation.
Shipping Methods: Our DT4C AC Relay Iron Core supports multiple shipping methods. Door-to-door service is available for bulk orders. Regular orders have short delivery times, and urgent orders can be expedited.
