Glossary of Metal Terms
We know firsthand that the world of metal recycling can be full of jargon and acronyms. At Green Earth Recycling, we're here to help wether you're a metal worker professional or just someone looking to responsibly recycle your washing machine.
ALLOY
A mixture or metallic solid solution composed of two or more elements. Examples of alloys include solder, brass, pewter, phosphor bronze and amalgam.
AUTOMOTIVE SHREDDER RESIDUE (ASR)
Material left over after a car or vehicle has been shredded and the ferrous metal and other sellable materials, such as tires, fluids and the catalytic converter, have been separated. This is also known as fluff.
BALER
A machine that compresses recycled metal into condensed cubes ready for shipment and transportation.
BARS
Steel shaped into long and thin units used to make furniture and railings.
CATALYTIC CONVERTER (CAT)
A catalytic converter or CAT is a vehicle emissions control device which converts the toxic by-products of combustion in the exhaust of an internal combustion engine to less toxic substances by way of a catalysed chemical reactions.
COILS
Sheets of steel that are wound up into coils for transportation.
DEPOLLUTION
The process by which a car is stripped of hazardous material and made safe for further recycling.
ELV
End-of-Life Vehicle. A vehicle that is no longer fit for use that needs to be recycled or broken down for parts.
FEEDSTOCK
Any material used at the beginning of an industrial process, such as vehicles that would feed a shredder.
FERROUS METAL
Materials mainly containing the element iron, i.e. iron and steel.
FOUNDRY
A workshop or factory for casting metal. Foundries melt the metal into liquid that can be poured into a mould for casting into the desired shape for resale.
GROSS TON
Equivalent to 2,240 pounds. Often used to measure ferrous scrap.
HAMMERMILL
A high-speed rotor of large hammers used to pulverize metal objects into smaller pieces, used within a shredder.
MAGNETIC SEPARATION
The removal of ferrous metals from other materials using magnets. The magnet can be in-built into the processing machine or simply attached to the crane maneuvering items around the scrap yard.
NO. 2 SCRAP
Ferrous scrap containing iron and steel between ¼ and 1/8 of an inch thick, and measuring no more than 60 inches by 18 inches, to fit in a standard charging box.
NON-FERROUS METAL
All metals except ferrous metals (iron and steel). Non-ferrous metals include aluminium, copper, lead, nickel, tin, titanium, zinc and alloys such as brass.
PLATE
Sheets of steel that are ¼-inch to 12- inches thick and over 8 inches wide.
PIG IRON
A product produced by smelting iron ore in blast furnaces often cast into ingots and sold as feedstock for foundries
PRIMARY METALS
A metal which has been produced from ore as distinct from that produced from scrap.
PROHIBITED WASTE
Waste that we cannot accept either because we cannot process it or it is hazardous.
PROMPT INDUSTRIAL SCRAP
Excess steel or other material generated at manufacturing facilities such as trimmings, stampings turnings or borings left over after processing.
REFINERY
A processing plant which produces high purity metal either by electrolysis, electrowinning or fire-refining. In copper and lead production, refining is preceded by smelting, but for tin, zinc and nickel, smelting and refining blend into one process to recover marketable quality metal from concentrates.
REINFORCING BAR (REBAR)
Steel bar that is used in concrete to reinforce the construction of roads, bridges and buildings.
RESIDUES
Secondary metal-containing materials that require smelting to recover the metal, as distinct from scrap which may only require melting and blending.
ROD
Round, thin steel that is wound for transportation.
SHEET
Thin steel, rolled flat and coiled for transportation.
SHORT TON
Equivalent to 2,000 pounds, a ton measurement used in the USA.
SLAB
Thick steel that is 10 inches thick and between 30 inches to 85 inches wide.
SHEAR
A machine that is used to cut bulky metals into smaller units for transportation.
SHIPBREAKING
The demolition of marine structures for either a source of parts, which can be sold for re-use, or for the extraction of raw materials, mostly metal.
SHREDDER
A powerful machine used in the scrap industry to batter large items of scrap such as cars and domestic equipment into fragments.
SPECIAL BAR QUALITY (SBQ)
A type of steel bar with metallurgic specifications made to fill customized orders.
STRUCTURAL
Large and thick steel pieces used by the construction industry.
TOLL PROCESSING
Performing a process to improve material belonging to another company. This could be the processing of prompt scrap from a manufacturer or shredding auto feedstock from a smaller scrap merchant.
TURNINGS
Small bits of scrap generated through industrial and manufacturing operations.
VIRGIN METAL
Primary metal produced from ore.
WASTE ELECTRICAL AND ELECTRONIC EQUIPMENT (WEEE)
End-of-life electrical and electronic equipment covering everything with a plug or battery.
WHITE GOODS
Large household appliances such as refrigerators, washers and dryers.
WIRE
The thinnest type of steel rods.
