High Permeability Winding Notched Core - AEKL01002 | China Suppliers & Factory for Permalloy Wound Core
Wound-type Annular Cut Iron Core
High-performance electromagnetic component cores engineered with premium permalloy materials for maximum efficiency and precision.
Application Fields
Commonly used in electromagnetic components such as small and medium-sized transformers, mutual inductors, magnetic amplifiers, and leakage protectors.
Core Material
High permeability permalloy soft tape material, such as 1J85, offering excellent performance, high magnetic permeability, and low loss.
Product Advantages
High efficiency and energy saving. Compared with stacked iron cores, the no-load loss of the wound core is reduced by 7%-10%, and the no-load current is reduced by 50%-75%.
Exquisite Craftsmanship
Fully automatic winding, smooth and tight, no shear waste. Material utilization rate is nearly 100%, and production efficiency is 5-10 times higher than stacked iron cores.
Low Noise & Environmental
The integrated structure reduces vibration and noise by 5-10dB compared with traditional stacked iron cores.
High Customization
To meet the diverse and precise needs of customers, various tailored specifications can be customized.
Process Features
CNC wire cutting ensures a precise opening size. The center line of the incision passes directly through the center of the inner circle. After annealing, the residual magnetism is less than 5GS (within the range of 0~2000GS).

Frequently Asked Questions (FAQ)
What are the main application fields for the wound-type annular cut iron core?
These cores are widely used in electromagnetic components, including small and medium-sized transformers, mutual inductors, magnetic amplifiers, and leakage protectors.
Why is the annealing process necessary after processing?
Annealing is essential to eliminate the internal stress generated during processing. This treatment reduces the residual magnetism of the iron core to less than 5 Gauss, significantly improving magnetic properties and stability.
What core materials are used, and what are their properties?
The cores are made of high permeability permalloy soft tape materials, such as 1J85 and 1J79B. These materials provide outstanding magnetic permeability and extremely low loss.
How does a wound core compare to a traditional stacked iron core?
Wound cores reduce no-load loss by 7%-10% and no-load current by 50%-75%. They also lower noise levels by 5-10dB and offer a material utilization rate of nearly 100% due to no shear waste.
What are the key process features of the cutting method?
The cores utilize CNC wire cutting to ensure precise opening sizes, where the center line of the incision passes directly through the center of the inner circle, maintaining structural balance and low residual magnetism.
Can these wound-type annular cut iron cores be customized?
Yes, they offer a high degree of customization. Various specifications and dimensions can be tailored to meet the specific requirements of different electromagnetic applications.
