Our 1J79 Mumetal tube is a rockstar for magnetic shielding in electronics. Crafted from a nickel-iron blend with copper and molybdenum, it delivers ultra-high magnetic permeability (~80,000) and super low coercivity, making it perfect for blocking unwanted magnetic fields. With a saturation magnetization of ~0.8 T and high electrical resistivity (~6×10⁻⁷ Ω·m), it keeps energy losses low in high-frequency setups up to 300 kHz. Its mechanical stats are solid—410 MPa tensile strength and 30% elongation—making it durable and easy to work with. For shielding sensitive electronics or building precision sensors, our 1J79 Mumetal tube is a game-changer.
