Stress Relieved Ignition Coil Passivated Magnetic Core

Non‑Oriented Silicon Steel Clinched Magnetic Core for Pen‑Type Ignition Coils Product Overview Pen‑type ignition cores deployed in gasoline engines, gas engines and motorcycle assemblies are exposed to continuous high‑temperature working environments. Ordinary magnetic cores may suffer high iron loss, obvious magnetic attenuation and inconsistent multi‑cylinder ignition output. These failures result in weak ignition energy, rough idling vibration and shortened service life for finished high‑voltage packs. Our ignition coil cores adopt high‑permeability non‑oriented silicon‑steel raw material and go through high‑speed stamping, clinch forming, stress‑relief annealing and insulation‑passivation treatments. This Stress Relieved Ignition Coil Laminated Core eliminates internal processing residual stress. The Insulation Passivated Silicon Steel Magnetic Core delivers reliable inter‑sheet isolation and surface protection. As a Low Core Loss Engine Ignition Lamination Part, it achieves low m…
