Chuck Metals is a reliable manufacturer and supplier of Mu Metal Bars and Rods right here in Singapore, Pulau Ujong. We take pride in delivering precision-engineered products that excel in magnetic shielding applications. Our Mu Metal bars and rods are crafted from high-permeability nickel-iron alloys, which means they’re fantastic at protecting sensitive equipment from low-frequency magnetic fields. Renowned for their durability, workability, and consistent performance, these bars adhere to international quality standards and can be customized to meet a variety of industrial needs.
Typically, Mu Metal consists of about 77–80% nickel, 15% iron, along with trace amounts of copper and molybdenum. This special blend gives it an incredibly high magnetic permeability, making it effective at reducing magnetic interference. In terms of mechanical properties, you can expect good ductility, excellent formability, and stable performance even after fabrication, provided they are properly annealed.

Yes, Mu Metal bars are recyclable. They are made of a high-purity nickel-iron alloy, which can be melted down and reused in various industrial applications, reducing waste and environmental impact.
Mu Metal bars can be welded, but it is challenging due to their high magnetic permeability and low melting point. Special techniques and care are needed to prevent distortion or loss of properties.
Mu Metal rods are typically available in sizes ranging from 0.125 inches to 4 inches in diameter. Finishes include annealed, cold worked, and polished, depending on the specific requirements.
These bars and rods find their way into a range of applications, including electronic enclosures, transformer cores, MRI room shielding, aerospace instrumentation, and precision measuring devices. Thanks to their exceptional magnetic shielding capabilities, Mu Metal bars are a go-to choice for industries that need to guard against electromagnetic disturbances and ensure the accuracy of sensitive equipment.






We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
