Ferrous metals are magnetic whereas non-ferrous metals are not. Ferrous metals are more prone to corrosion or rust due to the inclusion of iron where non-ferrous are more rust resistant. Non-ferrous metals are typically lightweight where ferrous metals are heavier. Non-ferrous metals are easily recyclable. Non-ferrous metals include aluminium, copper, lead, tin, titanium and zinc, and alloys such as brass. Precious metals such as gold, silver and platinum and exotic or rare metals such as mercury, tungsten, beryllium, bismuth, cerium, cadmium, niobium, indium, gallium, germanium, lithium, selenium, tantalum, tellurium, vanadium and zirconium are also non-ferrous. We have added rubber and wood companies. Ferrous means 'iron' or 'iron containing'. Rubber and wood have no iron in them |
