Goodfellow offers a range of nickel/iron alloy pellets including Ni80/Fe20 which contains 80% nickel and 20% iron. This alloy exhibits high permeability, low coercivity, and low core loss. The pellets are well-suited for applications in magnetic screening and electromagnetic shielding. Their composition allows them to be attracted to magnets while also blocking electromagnetic fields. The nickel/iron ratio provides an optimal combination of magnetic properties and cost-effectiveness. Within Goodfellow's selection of alloy pellets, Ni80/Fe20 stands out for its versatility in magnetic and electromagnetic applications.
