At TT&E, identifying metal scraps is key in the organization and recycling of metal. Metals fall into two main categories, ferrous and non-ferrous.
Ferrous metals have to be separated from non-ferrous metals. Ferrous metals are basically any metals that contain iron, and typically they will stick to a magnet. Other than iron based metals, the other common elements that will stick to a magnet are nickel and cobalt.
Steel, an iron alloy(ferrous), is the most commonly recycled metal in the world. By recycling steel, CO2 emissions, air pollution, and energy/water consumption are reduced in comparison to extracting ore to create metals.
Below is a list of some common ferrous metals:
These valuable metals are easily distinguished from ferrous metals by none other than a magnet. Non-ferrous metals are generally more expensive than ferrous metals because of their different properties like being lower weight, non-magnetic, and in some cases having higher conductivity.
Below is a list of some common non-ferrous metals:
