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 properties and stability. They’re commonly utilized in transformers, magnetic shields, inductors, and sensors due to their high magnetic permeability. Electrical and electronics manufacturers rely on them for precision instruments, relays, and electromagnetic components. Moreover, they play a vital role in aerospace, defense, and research applications where low coercivity and reliable magnetic performance are essential. With their blend of durability, machinability, and superior magnetic characteristics, Permalloy Bars and Rods are the perfect choice for advanced industrial and technological applications.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
