Our 1J85 Soft Magnetic Alloy bar is a top-tier choice for RF transformers. Crafted from a nickel-iron blend with copper, molybdenum, and silicon, it delivers ultra-high magnetic permeability (~100,000) and low coercivity for exceptional signal clarity. With a saturation magnetization of ~0.8 T and high electrical resistivity (~6×10⁻⁷ Ω·m), it minimizes energy losses in high-frequency setups. Its mechanical stats are solid too—420 MPa tensile strength and 28% elongation—making it easy to machine and reliable in tough conditions. For RF transformers, sensors, or shielding, our 1J85 bar is built to perform.
