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.
You’ll find Permalloy Bars and Rods widely used in various applications that require high magnetic performance, mechanical strength, and durability. They are often found in transformers, inductors, magnetic shielding, and electronic sensors. This alloy is also perfect for precision instruments, electromagnetic devices, and laboratory equipment where low coercivity and high permeability are crucial. Furthermore, Permalloy Bars and Rods play a vital role in power generation, telecommunications, and high-precision industrial components that demand reliable magnetic performance.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
