Introduction

The rapid growth of global electronics, energy, and communication industries has created a strong demand for high-performance magnetic cores. Among the most reliable solutions are permalloy strip cores, known for their exceptional permeability, low energy loss, and stable performance.

China has emerged as a leading hub for permalloy strip core manufacturing, offering world-class quality, advanced technology, and cost competitiveness. With numerous factories specializing in custom production, businesses across the globe are turning to China for sourcing permalloy strip cores.

This article explores what permalloy strip cores are, why China is a global leader in production, and how to select the right factory for your business needs.

What is a Permalloy Strip Core?

Definition

A permalloy strip core is a magnetic core manufactured using thin strips of permalloy alloy—typically 80% nickel and 20% iron—that are precisely processed through rolling, annealing, and cutting.

Key Properties

• High Magnetic Permeability: Enhances sensitivity in low-field applications.

• Low Coercivity: Reduces hysteresis losses for better energy efficiency.

• Low Eddy Current Loss: The thin strip construction minimizes energy waste.

• Flexibility: Can be processed into various core shapes such as C-cores, toroidal cores, and E-cores.

Applications

• Transformers (power, audio, and precision)

• Inductors and chokes

• Magnetic sensors

• Power supplies

• Renewable energy converters

• Communication devices
