Sahil Metals, based in Riyadh, Saudi Arabia, stands out as a leading manufacturer and supplier of top-notch metal products, including Permalloy bars and rods. With a reputation for expertise and precision, Sahil Metals provides Permalloy components that boast remarkable magnetic properties and mechanical strength. These bars and rods are carefully crafted to adhere to strict industry standards, catering to a range of sectors like electronics, telecommunications, and electrical engineering. Committed to quality and reliability, Sahil Metals ensures that its Permalloy products meet the demands of advanced technology and industrial applications throughout the region.
Permalloy bars and rods are primarily made up of around 80% nickel and 20% iron, often with trace amounts of other elements to boost their magnetic characteristics. This distinctive composition grants Permalloy its notable high magnetic permeability and low coercivity, making it perfect for efficient magnetic flux conduction. On the mechanical side, these bars and rods demonstrate good ductility and tensile strength in the range of 400-600 MPa, along with excellent resistance to magnetic losses. Their stability and performance are vital for precision electromagnetic 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.
Thanks to their superior magnetic permeability, Permalloy bars and rods find extensive use in magnetic shielding, transformer cores, inductors, and sensors. They play a crucial role in electrical and electronic devices, including telecommunications gear and precision instruments. Their capacity to reduce energy loss and maintain stable magnetic properties under varying conditions makes Permalloy bars and rods incredibly valuable in industries that demand efficient magnetic performance and reliability.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
