Nial Sheets and Plates is a trusted manufacturer and supplier located in Houston, USA, focusing on high-quality Permalloy foil for advanced magnetic and shielding applications. Permalloy, a nickel-iron soft magnetic alloy, is well-known for its impressive magnetic permeability and low coercivity, making it perfect for sensitive electronic, medical, and aerospace components. Nial provides Permalloy foil in a range of thicknesses and custom-cut sizes, ensuring tight tolerances and consistent material quality. Catering to demanding industries like defense, telecommunications, and scientific research, Nial guarantees precision, durability, and reliable performance with every Permalloy foil product.
Typically, Permalloy foil consists of about 80% nickel and 20% iron, although specific grades can vary. This alloy is celebrated for its outstanding magnetic properties, especially its ability to efficiently concentrate and redirect magnetic flux, which is crucial for effective shielding applications. The foil boasts high magnetic permeability (up to 100,000 or more), low core loss, and minimal hysteresis. Mechanically, it is soft and ductile, with a tensile strength usually around 450–550 MPa, and is often annealed in a hydrogen atmosphere to enhance its magnetic characteristics.
