Is Galvanised Steel Magnetic? – Mocayo Indexing Plunger

Magnetic Properties of Galvanised Steel

Is Galvanised Steel Magnetic? This is a crucial question many engineers consider when selecting materials for precision applications. In practice, the magnetic behavior of galvanised steel is influenced by several key factors:

• Base Material Composition: Low carbon steel (such as Q235) has strong magnetic properties, significantly higher than stainless steel.

• Coating Thickness: The thickness of the zinc layer has minimal impact on the overall magnetism.

• Processing Methods: Cold working processes can slightly enhance magnetic properties.

“It is important to note that although galvanised steel is magnetic, its magnetic permeability may slightly decrease as the zinc coating thickness increases,” Mocayo material engineers emphasize.
