Metal Types and Recycling Process

Metal Types and Recycling Process

Steel and iron are the most recycled materials in the world due in part to the opportunity to recover large structures as well as the ease of reprocessing. The use of magnets in the sorting process enables recyclers to easily separate them from the mixed waste stream. Every year, around 400 million tons of metal are recycled worldwide.

Reaction of iron with air. Iron metal reacts in moist air by oxidation to give a hydrated iron oxide. This does not protect the iron surface to further reaction since it flakes off, exposing more iron metal to oxidation. This process is called rusting and is familiar to any car owner. Finely divided iron powder is pyrophoric, making it a fire risk.

For example, it''s rare for lowcarbon steels to require normalization. That being said, if such steels are normalized, no harm will come to the material. Also, when iron castings have a consistent thickness and equal section sizes, they are generally put through the annealing process, rather than the normalization process.

Metal Profile: Iron Properties and Characteristics

Iron''s most troublesome characteristic is its tendency to form rust. Rust (or ferric oxide) is a brown, crumbly compound that is produced when the iron is exposed to oxygen. The oxygen gas that is contained in water speeds up the process of corrosion. The rate of rust—how quickly iron turns into ferric oxide—is determined by the oxygen
