Is Steel Magnetic? || Magnetic Metals List

Like most metals, whether or not steel is magnetic depends entirely on its composition. Though steel is often magnetic, that’s not always the case. While steel is a metal alloy made primarily of iron, steel being magnetic depends on its structure. For example, most carbon steel is magnetic due to its iron content, while types of austenitic steel such as surgical steel, are not. Even more, steel’s range of magnetism can vary based on the specific type and manufacturing process, ranging from highly magnetic to virtually non-magnetic.

Are all metals magnetic?

No, not all metals are magnetic. In fact, most metals exhibit no significant magnetic properties. Only a handful of elements, primarily iron, nickel, and cobalt, display strong ferromagnetic behavior. These elements are known for their strong magnetic properties and are often used in various applications, such as magnets, transformers, and electronic devices. 

What metals are magnetic? And which are non-magnetic?

Magnetic materials are typically classified as either ferromagnetic, paramagnetic, or diamagnetic. Ferromagnetic materials, like ferrous metals such as iron, cobalt, and nickel, exhibit strong magnetic properties and can be permanently magnetized. Paramagnetic materials have a weak attraction to magnetic fields, while they repel diamagnetic materials. That’s why metals such as aluminum, copper, gold, and silver are often used in electrical conductors and jewelry.

Here’s a list of common magnetic elements and materials:

Magnetic metals FAQs

Do magnets stick to steel?

Yes, but magnets can only stick to steel if the steel has been magnetized. Unmagnetized steel does not have a strong magnetic field and will not be attracted to a magnet.

Is carbon steel magnetic?

Carbon steel can be magnetic, but it depends on its carbon content and whether it has been magnetized. Steels with higher carbon content tend to be more magnetic due to the increased number of iron atoms in their structure.

Is galvanized steel magnetic?

Galvanized steel is typically not magnetic. The zinc coating on galvanized steel can interfere with its magnetic properties and prevent it from being attracted to a magnet.

Is alloy steel magnetic?

Alloy steel can be magnetic or non-magnetic depending on the specific alloying elements present. Alloying elements that are themselves magnetic, such as nickel and cobalt, can enhance the magnetic properties of steel. On the other hand, alloying elements that are non-magnetic or have opposing magnetic properties can reduce or eliminate the steel’s magnetism.

Is stainless steel magnetic?

Stainless steel can be magnetic or non-magnetic depending on its composition. Austenitic stainless steels, which contain high levels of nickel and chromium, are generally non-magnetic due to the non-magnetic nature of these elements. Ferritic stainless steels, on the other hand, are magnetic due to their iron-rich composition.

Is surgical steel magnetic?

Surgical steel is typically non-magnetic. It is often made from austenitic stainless steel, which is known for its non-magnetic properties and biocompatibility. This is important in medical applications to prevent interference with magnetic imaging equipment and to avoid potential health risks associated with magnetic fields.
