Process Features
Welding or lamination riveting forming, fast and efficient.
Permalloy (such as 1J85 and 1J50) is a soft magnetic material with high magnetic permeability and low loss. This means that under the same magnetic field strength, permalloy can produce stronger magnetic flux density, thereby improving the efficiency and performance of electromagnetic components. The high magnetic permeability enables the laminated core to exhibit excellent magnetic properties even under low magnetic field intensity, making it suitable for various electromagnetic applications requiring high sensitivity and precision.
In terms of manufacturing process, laminated cores are usually formed by welding or lamination riveting. These process methods are fast and efficient and can produce high-quality iron cores on a large scale. The welding process ensures that the various parts of the iron core are tightly combined to form a whole, thereby improving the mechanical strength and stability of the iron core. The laminated riveting process forms an integral iron core by stacking and riveting multiple thin sheets of material together. This method not only improves the mechanical strength of the iron core, but also effectively reduces eddy current losses.
The application of laminated cores in electromagnetic components has significant advantages. Its high magnetic permeability, low losses and excellent mechanical properties make it ideal for a variety of electromagnetic components. Whether in transformers, transformers, magnetic amplifiers or other electromagnetic applications, laminated cores can provide excellent performance and reliability to meet the needs of various high-performance electromagnetic components.
