Non-ferrous metals are metals that do not contain significant amounts of iron. This category includes metals like aluminum, copper, lead, zinc, and nickel. These metals are known for their resistance to corrosion, lightweight properties, and excellent conductivity, making them valuable in various industries, including construction, electronics, and transportation. Unlike ferrous metals, which can rust and are magnetic, non-ferrous metals are often more malleable and ductile. They are used in applications ranging from aircraft manufacturing to electrical wiring. The recycling of non-ferrous metals is also important, as it conserves resources and reduces environmental impact.
