A non-ferrous metal is a metal that does not contain significant amounts of iron. These metals are generally not magnetic and are more resistant to corrosion and rust compared to ferrous metals (which do contain iron).
Common examples of non-ferrous metals include:
In the painting and construction industry, non-ferrous metals are often used for their lightweight properties, durability, and resistance to environmental elements. When painting non-ferrous surfaces, special surface preparation and primers (such as etch primers) are typically required to ensure proper adhesion.
