Permalloy Rod and Baris an alloy consisting of 80% nickel and 20% iron. It is a high-permeability alloy employed in most magnetic applications. Its mechanical characteristics include a tensile strength of about 500 MPa, elongation of roughly 30-40%, and yield strength of about 200 MPa. It offers outstanding magnetic permeability, low coercivity, and high saturation magnetization, which makes it well suited for transformer cores, magnetic shielding, and other electromagnetic uses. The electrical resistivity of Permalloy is approximately 0.5 µΩ·cm. It provides good corrosion resistance owing to its high nickel content and is therefore durable across various environmental conditions.

Permalloy bars are typically not very prone to galvanic corrosion, since they offer good corrosion resistance. Nevertheless, when placed in contact with dissimilar metals, galvanic corrosion can still take place under certain conditions.
Yes, Permalloy bars are weldable, but because of their elevated nickel content, specialized welding methods like TIG or laser welding, along with appropriate safeguards, are required to preserve their magnetic properties.
Permalloy rods come in a range of sizes, generally spanning from 1/16" to 4" in diameter. Typical finishes include bright, polished, or cold-drawn options, based on what the application calls for.
We supply products accompanied by both mill test certificates and third-party test certificates, guaranteeing the highest standards of quality and compliance.
