Permalloy is a nickel-iron magnetic alloy, typically made up of about 80% nickel and 20% iron, although variations can occur based on specific applications. This unique blend provides incredibly high magnetic permeability, low coercivity, and minimal core loss. Generally, Permalloy bars and rods boast a tensile strength of around 500–600 MPa, along with good ductility and formability. The alloy retains stable magnetic properties across a range of temperatures and is renowned for its excellent shielding effectiveness against low-frequency magnetic fields, making it a fantastic choice for electromagnetic and magnetic applications.

Permalloy bars are generally not highly susceptible to galvanic corrosion, as they have good resistance to corrosion. However, when in contact with dissimilar metals, galvanic corrosion may still occur under certain conditions.
Yes, Permalloy bars can be welded, but due to their high nickel content, specialized welding techniques, such as TIG or laser welding, and proper precautions are necessary to maintain magnetic properties.
Permalloy rods are available in various sizes, typically ranging from 1/16" to 4" in diameter. Common finishes include bright, polished, or cold-drawn finishes, depending on the application requirements.
Permalloy Bars and Rods find extensive use in industries that demand exceptional magnetic performance and signal integrity. In the electronics sector, they are utilized for magnetic shielding, transformers, inductors, and magnetic cores due to their high permeability and low energy loss. In telecommunications, Permalloy components improve signal quality in devices such as sensors, modulators, and antennas. The aerospace and defense industries rely on them for navigation systems and magnetic sensors. They also play a crucial role in MRI equipment, power electronics, and audio transformers. The unique magnetic properties of Permalloy make it indispensable for precision applications that require reliable electromagnetic performance.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
