Welcome to Maduka Metals, your trusted partner for precision-engineered materials right here in Abuja. We take pride in supplying industries and innovators across Nigeria with high-performance solutions, including our specialized Mu Metal bar and rod. This unique alloy is at the heart of modern technology, designed specifically to create silent, protected spaces for sensitive electronics by offering an exceptional shield against magnetic interference, ensuring your most critical equipment operates without disruption.
The secret to Mu Metal’s performance lies in its precise composition, primarily nickel and iron, which gives it a remarkably high magnetic permeability. This means it acts as a super-efficient conduit for magnetic field lines, drawing them away from the areas you need to protect. While it is a relatively soft material mechanically, this very characteristic is essential for its magnetic shielding function, allowing the domains within the metal to align easily and form a powerful barrier against interference.

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.
The primary use for our Mu Metal bar and rod is in fabricating custom magnetic shields for a wide range of sensitive equipment. You’ll find it essential in medical imaging devices like MRI machines, in scientific research laboratories for accurate measurements, and within the aerospace and telecommunications industries to protect vital instrumentation. Craftsmen and engineers use these stock forms to machine precise components that safeguard everything from data storage systems to advanced sensors, ensuring clarity and reliability in increasingly noisy electronic environments.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
