The Scrapper’s Dictionary: Understanding Metal Grades & E-Waste
Your comprehensive guide to identifying scrap metal value, understanding electronic components, and navigating Pennsylvania's recycling standards.
In the world of professional recycling, knowledge is literally money. At Scrapped it, serving Montgomery County and the greater Eastern Pennsylvania region, we believe that understanding what you have is the first step toward responsible disposal and value recovery. Whether you are a homeowner cleaning out a garage, a business upgrading its server room, or a contractor at a job site, this dictionary will help you distinguish between high-value non-ferrous metals and standard ferrous scrap.
Our motto is "Don't trash it - Scrap it!" and this guide ensures you know exactly why that old appliance or "dead" laptop shouldn't end up in a landfill.
Common Scrap Metal Grades
#1 Copper
High-quality copper that is clean, unalloyed, and uncoated. This includes bus bars, clippings, and clean pipe/tubing. It must be free of solder, paint, and brass fittings to maintain its premium status.
#2 Copper
Copper that has "contamination" such as paint, solder, or oxidation. While still very valuable, it contains 94–96% copper content and usually consists of unalloyed wire or pipe with fittings still attached.
Bare Bright Copper
The "Gold Standard" of scrap. This is clean, uncoated, unalloyed copper wire, at least 16 gauge (pencil lead thickness) or thicker. It must be stripped of all insulation and look shiny and new.
THHN Wire
Thermoplastic High Heat-resistant Nylon-coated wire. This is common building wire. Scrappers value this because once the insulation is removed, it often yields high-grade copper.
Ferrous Metals
Metals that contain iron and are magnetic (e.g., steel, cast iron). While they are typically lower in value than non-ferrous metals, they are recycled in massive volumes from appliances and structural beams.
Non-Ferrous Metals
Metals that do not contain iron and are not magnetic. This category includes copper, aluminum, brass, and lead. These metals are highly resistant to corrosion and command much higher prices at the scale.
HMS 1 & 2
Heavy Melting Steel. HMS 1 is clean, structural steel at least 1/4 inch thick. HMS 2 is slightly thinner and may include galvanized or black steel. Both are staples of industrial recycling.
Clean vs. Dirty Aluminum
"Clean" aluminum is free of steel, plastic, or rubber attachments (like siding or clean cans). "Dirty" aluminum has screws, glass, or plastic attached, which lowers its recovery value.
Yellow Brass
The most common type of brass, found in plumbing fixtures, keys, and decorative items. It is an alloy of copper and zinc and has a bright, yellowish hue.
Cast Iron
A heavy, brittle ferrous metal often found in old sewer pipes, engine blocks, and heavy cookware. It is easily identified by its weight and the way it breaks into shards when struck with force.
E-Waste & Electronic Grading
High-Grade Motherboards
Found in servers and high-end desktop computers. These contain a higher concentration of precious metals like gold, silver, and palladium on the connectors and integrated circuits.
Low-Grade Boards
Commonly found in "brown goods" like VCRs, printers, and older monitors. They have fewer precious metal components compared to computer motherboards but still require proper recycling to reclaim base metals.
Covered Device (CDRA)
Under Pennsylvania’s Covered Device Recycling Act, items like desktop computers, laptops, and monitors are banned from landfills and must be processed by certified recyclers like Scrapped it.
Data Destruction
The process of ensuring all personal information is removed from a device. This can involve software wiping or physical destruction (shredding) of hard drives and solid-state drives.
WEEE
An acronym for Waste Electrical and Electronic Equipment. This is the international standard term for anything with a plug or battery that has reached the end of its useful life.
Peripheral Devices
Auxiliary devices that connect to a computer but aren't part of the core architecture, such as keyboards, mice, scanners, and external speakers.
RAM (Random Access Memory)
Small circuit boards from computers that are highly valued in E-waste recycling due to the gold plating on the contact "fingers."
Hard Drive (HDD) vs SSD
HDDs contain aluminum casings and magnetic platters; SSDs (Solid State Drives) are purely electronic and are graded similarly to high-end circuit boards.
The Recycler's Secret: The Magnet Test
The most important tool in any scrapper's pocket isn't a wrench—it's a magnet. Here is how professional recyclers in Pennsylvania use it to categorize materials quickly:
- If the magnet sticks: You have a Ferrous metal (Steel or Iron). These are common but generally have lower market value.
- If the magnet does NOT stick: You likely have a Non-Ferrous metal (Copper, Aluminum, Brass, or Stainless Steel). These are your high-value items.
- Testing Stainless Steel: While most stainless steel is non-magnetic, lower grades (like those used in some appliances) may have a slight magnetic pull.
- Identifying "Irony" Aluminum: If a magnet sticks to a piece of aluminum, it means there are steel screws or brackets attached, classifying it as "Dirty" or "Irony" aluminum.
Industry Standard Terminology
Tare Weight
The weight of an empty vehicle or container. To find the weight of your scrap, we subtract the tare weight from the gross weight (vehicle + scrap).
White Goods
A term used for large household appliances like refrigerators, stoves, washing machines, and dryers. These are primarily comprised of steel but contain valuable motors and wiring.
Alloy
A metal made by combining two or more metallic elements (e.g., brass is an alloy of copper and zinc). Alloys often have specific recycling requirements compared to pure metals.
Recovery Rate
The percentage of usable metal that can be extracted from a specific item after processing and smelting. High-grade wires have a much higher recovery rate than insulated thin cords.
ICW (Insulated Copper Wire)
Copper wire that still has its plastic or rubber coating. It is usually graded by the percentage of copper it contains (e.g., 10%, 40%, or 70% recovery).
Ballast
Found in older fluorescent light fixtures. Modern ones are electronic, but older ones contain heavy copper coils. Note: Some very old ballasts may contain PCBs and require specialized hazardous waste handling.
Sealed Units
The compressors found in refrigerators and air conditioners. These contain high-quality copper windings inside a heavy steel shell.
Catalytic Converter
An exhaust emission control device that contains precious metals like platinum, rhodium, and palladium. These are highly regulated and among the most valuable automotive scrap items.
Frequently Asked Questions
Our model focuses on volume and the reclamation of valuable materials. Most electronics and scrap metals have enough "melt value" to cover the cost of logistics. However, certain items (like those covered by the PA CDRA) require specialized processing and documentation, which influences our service schedule.
This is our recycler's motto. It represents the circular economy—taking yesterday's obsolete technology and waste and processing it into the raw materials needed for tomorrow's innovations.
You don't have to! While stripped "Bare Bright" copper is worth more, we accept insulated copper wire (ICW) in all forms. We have the equipment to process and recycle it properly regardless of its state.
We are based in Montgomery County and serve residential, commercial, and municipal clients throughout Eastern Pennsylvania.
If your electronics or appliances are still in working order, we prioritize reuse. We often donate working equipment to charity or resell it to families in need at heavily discounted rates, ensuring the longest possible lifecycle for every device.
