Non-ferrous metals (NF metals)

Non-ferrous metals (abbreviated NF metals) are metals and alloys that do not contain significant amounts of iron. Unlike ferrous metals such as steel or cast iron, non-ferrous metals are valued for their light weight, corrosion resistance, and excellent electrical and thermal conductivity. They play a crucial role in numerous industrial and high-tech applications.

Key properties

• Corrosion resistance – Many NF metals form stable oxide layers that protect against environmental influences
• Low density – Ideal for lightweight construction, especially in transportation and aerospace
• High electrical and thermal conductivity – Particularly copper, silver, and aluminum
• Non-magnetic – Suitable for sensitive applications in electronics and instrumentation
• Recyclability – Economically and ecologically valuable due to high material recovery rates

Common non-ferrous metals

• Copper (Cu) – Outstanding conductivity and corrosion resistance
• Aluminium (Al) – Lightweight, formable, and oxidation-resistant
• Zinc (Zn) – Used for corrosion protection (e.g. galvanizing), excellent castability
• Nickel (Ni) – Heat- and chemical-resistant, used in high-performance alloys
• Magnesium (Mg) – Extremely light, used in ultralight metal structures
• Lead (Pb) – Soft, dense, and resistant to many acids

Typical applications

• Electrical engineering – Conductors, terminals, windings
• Automotive and aerospace – Lightweight components made from aluminium and magnesium alloys
• Mechanical engineering – Bearings, housings, valves
• Construction industry – Roofing, façade panels, structural profiles
• Medical and chemical industries – Corrosion-resistant components for aggressive environments
