A-Z of Scrap Master Terminology:

  • Aluminum (Al): A lightweight, non-ferrous, non-magnetic metal. Common forms include cans (UBC), extrusion (window frames), and cast aluminum (engine parts). High value.

  • Appliances (White Goods): Large household machines like refrigerators, washers, dryers, stoves. Primarily steel, but contain valuable non-ferrous components (copper motors, wiring).

  • Baled: Scrap metal that has been compacted into a dense block or cube by specialized machinery. This makes it easier to transport.

  • Bare Bright Copper: The highest grade of copper scrap. It's clean, unoxidized, unalloyed, and uninsulated wire, usually 16 gauge or thicker. Fetches top dollar.

  • Brass (Br): A non-ferrous, non-magnetic alloy of copper and zinc. Appears yellowish-gold. Common in plumbing fixtures, keys, and decorative items. Good value.

  • Broker: An intermediary who buys scrap from collectors (often in large quantities) and sells to larger processing facilities or mills.

  • Carbon Steel: The most common type of steel, an alloy of iron and carbon.

  • Cast Iron: A type of ferrous metal (magnetic) that is very heavy and brittle. Found in old radiators, bathtubs, engine blocks, and sewer grates. Lower value than non-ferrous.

  • Catalytic Converter (Cat): A component of vehicle exhaust systems containing precious metals like platinum, palladium, and rhodium. Very high value; sold by unit, not weight, and prices vary widely.

  • Clean Scrap: Metal that is completely free of any non-metal contaminants (plastic, rubber, wood, paint, dirt, glass) or other metal alloys. Always fetches a higher price.

  • Common Metals: Generally refers to ferrous metals (steel, iron) due to their abundance and lower individual value.

  • Contaminants: Any non-metal material (plastic, rubber, dirt, wood, paint, glass, fluids) attached to the metal, which will reduce its value if not removed.

  • Copper (Cu): A highly valuable non-ferrous, non-magnetic metal. Excellent conductor. Found in wires, pipes, motors. Graded by purity (Bare Bright, #1, #2).

  • Core: A term often used for used auto parts (like alternators, starters) that can be rebuilt. Some buyers pay extra for cores.

  • Degaussing: The process of removing magnetism. Not typically done by scrappers, but relevant for some metals.

  • Dirty Scrap: Metal that contains non-metal contaminants or is mixed with lower-value metals. Will be paid at a lower rate or rejected.

  • Dismantling/Breaking Down: The process of taking apart an item (like an appliance or car part) to separate different types of metals and remove contaminants.

  • Drum (or Barrel): Large metal containers often used for storing and transporting scrap.

  • E-waste (Electronic Waste): Discarded electronic devices (computers, circuit boards). Can contain small amounts of valuable metals but require specialized handling due to hazardous materials.

  • Ferrous Metals: Metals that contain iron and are magnetic. Primarily steel and cast iron. Lower value per pound.

  • Forklift: A powered industrial truck used to lift and move materials over short distances within a scrap yard.

  • Gauge: A measure of wire thickness (e.g., 10-gauge wire). Lower gauge numbers indicate thicker wire.

  • Genset: Short for "generator set," a unit comprising an engine and an electric generator. Can be a source of valuable copper.

  • Grabber/Grapple: A large, claw-like attachment on heavy machinery (like excavators) used to pick up and move large amounts of scrap metal.

  • Gross Weight: The total weight of your vehicle including your scrap load, measured on the main scale at the scrap yard.

  • High-Temp Wire: Electrical wire designed for high temperatures, often with specific insulation.

  • Hydraulics: Fluid power systems used in heavy machinery for crushing, shearing, or baling scrap.

  • Insulated Copper Wire (ICW): Copper wire still covered by its plastic or rubber insulation. Paid less than bare copper, as the yard must process it to remove insulation.

  • Iron (Fe): A common, magnetic ferrous metal. Often refers to cast iron or heavy structural steel.

  • Lead (Pb): A soft, heavy, non-ferrous metal. Found in car batteries (often exchanged), wheel weights, and old plumbing.

  • Light Iron/Sheet Iron: Common, thin ferrous scrap like appliance shells, old shelving, thin steel sheets. Lower value.

  • Load Securement: The practice of safely fastening scrap in your vehicle to prevent it from shifting or falling during transport.

  • Market Price: The current prevailing price for a specific metal, which fluctuates based on global supply and demand.

  • Mill: A large facility that processes raw materials (including scrap) into new metal products. Scrap yards sell to mills.

  • Net Weight: The actual weight of your scrap metal. Calculated by subtracting your vehicle's empty weight (tare) from the gross weight.

  • Non-Ferrous Metals: Metals that do NOT contain iron and are non-magnetic. Generally higher value per pound.

  • Pay Rate: The price per pound (or per ton) that the scrap yard pays for a specific type and grade of metal.

  • Payload Capacity: The maximum weight your vehicle (e.g., pickup truck) can safely carry, including passengers and cargo.

  • PPE (Personal Protective Equipment): Safety gear like gloves, safety glasses, steel-toe boots, and long clothing.

  • Pounds (Lb) / Ton: Units of weight for measuring scrap. 1 ton = 2000 pounds.

  • Processing: Any activity done to prepare scrap for resale or recycling, such as sorting, cleaning, dismantling, or baling.

  • Rads (Radiators): Often refers to car radiators. Can be Aluminum, Aluminum/Copper (Al/Cu), or Copper/Brass (Cu/Br).

  • Recycling Center: A facility that accepts materials for recycling, which may or may not pay for them.

  • Refining: The process of purifying metal after melting.

  • Roll-Off Container: Large, open-top dumpsters rented by scrap yards or waste management companies for large commercial or demolition projects.

  • Scale: The large weighing platform at a scrap yard where vehicles are weighed.

  • Scrap Dealer/Yard: A facility that buys scrap metal from individuals and businesses for processing and resale to mills.

  • Shred: Scrap metal (usually light iron) that has been run through a shredder, breaking it into smaller pieces.

  • Side Hustle: An additional income-generating activity done alongside one's main job.

  • Sorted: Metal that has been separated into distinct categories by type and grade.

  • Stainless Steel: A non-ferrous metal (though some grades are slightly magnetic) known for corrosion resistance. Found in sinks, some appliances. Good value.

  • Steel (St): A common ferrous metal, an alloy of iron and carbon.

  • Stripping: The act of removing insulation from wires or non-metal components from other metal items.

  • Tare Weight: The empty weight of your vehicle after you have unloaded all your scrap.

  • Tires (Tire Fee): Scrap yards often charge a per-tire fee if tires are left on rims, as they are not metal.

  • Transmitting/Transmission: The transmission from a vehicle. Contains steel, aluminum, and sometimes other metals. Requires draining fluids.

  • Tubing: Metal pipe, often referring to copper tubing from plumbing or AC units.

  • UBC (Used Beverage Cans): Aluminum soda and beer cans. Should be separated from other aluminum for best payout.

  • Weigh-In/Weigh-Out: The process of weighing your vehicle at the scrap yard (Gross on entry, Tare on exit).

  • Wire Stripper: A tool used to remove insulation from electrical wires.
