So, what exactly are **Permalloy Round Bars** made of? They primarily consist of about 80% nickel and 20% iron, with a dash of elements like molybdenum or copper to boost their magnetic features. This unique blend gives the alloy its impressive magnetic permeability, low coercivity, and minimal core loss. Permalloy is not only mechanically stable but also easy to fabricate, machine, or anneal, which enhances its magnetic softness. These bars retain their magnetic properties across a wide temperature range, making them perfect for precision magnetic and electrical components.
