Non-ferrous metals can be alloys or metals without any significant amounts of iron. Non-ferrous elements include all pure metals, except iron (Fe). While non-ferrous metals are more expensive than ferrous, they have many desirable properties such as lightweight (aluminum), high electrical conductivity (copper), resistance to corrosion (zinc), and nonmagnetic properties.
Non-ferrous materials can be used in the iron or steel industry, such as bauxite which is used to flux blast furnaces. The making of ferrous alloys is possible with other non-ferrous metals such as wolframite and pyrolusite. Many non-ferrous metals are less suitable for high-temperature applications because of their low melting points. However, companies such as Tecbo Group Pty Ltd. of nonferrous metals recycling handle them carefully by keeping everything in mind.

Non-ferrous materials include every metal and all alloys that do not contain iron. Aluminum, copper, lead, and nickel are all non-ferrous metals. Gold, silver, platinum, cobalt and mercury, tungsten, and tungsten are all non-ferrous metals. Non-ferrous metals are typically obtained from minerals such as silicates, carbonates, and sulfides. They then undergo electrolysis to refine them.
Ferrous metals are iron-rich, while non-ferrous metals have no iron. Cast irons and carbon steel are examples of ferrous metals. They have high carbon contents, making them susceptible to rust when they are exposed to moisture. This is not true for wrought iron which, due to its purity and stainless steel which are protected against corrosion by the presence of chromium, resist rust.
