Those wishing to sell discarded metal must know what are the differences between ferrous and non-ferrous metals for recycling. Understand, any ferrous metal contains the chemical element iron. Non-ferrous metal contains none. That said, when the question is asked in the scrap metal/recycling arena, there is more to be said.
1. The Essential Differences—The ferrous group,iron, cast iron, wrought iron and steel solve many problems in building and manufacturing for their strength and durability. Non-ferrous metals have different properties and uses. Copper, for example, is a supreme heat and electrical conductor. Tungsten and titanium are hard and thermally stable, so suit high heat environments,
2. Magnetic Differences—Put a sheet of paper over a magnet and pour on iron filings.Watch them snap into a pattern displaying the magnetic field. While other metals produce such fields, those of iron predominate in strength. Non-ferrous metals show no magnetism, so are inappropriate for a multitude of applications in which magnetism is central, like computer hard drives and speakers.
3. Alloys—Metals can be combined to serve useful purposes. These combinations are known as “alloys.” For example, iron is combined with chromium to produce stainless steel that does not corrode. Aluminum alloys also do not rust, are lightweight, and so are ideal for aircraft parts.
