The Magnet Test
Before you learn individual metals, learn the big picture: ferrous vs. non-ferrous.
- Ferrous metals = magnetic
- Contain iron
- Examples: steel, cast iron, wrought iron
- Rust when exposed to moisture
- Generally less valuable at scrap yards
- Non-ferrous metals = NOT magnetic
- No iron content
- Examples: aluminum, copper, brass, stainless steel (mostly)
- Don't rust (may corrode differently)
- Generally MORE valuable at scrap yards
How to test: Grab a fridge magnet. Hold it to your metal item. Does it stick? Ferrous. Doesn't stick? Non-ferrous.
The exception: Some stainless steel is magnetic, some isn't. We'll cover that later.
Steel — The Workhorse Metal
What it is: Iron + carbon alloy Common items: Food cans, car parts, appliances, construction materials, tools, furniture frames
Recyclability: Steel is the most recycled material in North America. More steel is recycled than plastic, paper, aluminum, and glass combined.
- How to identify:
- Magnetic (passes the magnet test)
- May have rust or surface corrosion
- Heavier than aluminum
- Often coated or painted
Sacramento value: $0.05-0.10 per pound for clean steel. Not much, but it adds up when you have a lot.
- What qualifies as "clean" steel:
- No paint, rust, or coatings (or minimal)
- No attachments (screws, plastic handles removed)
- Sorted from other metals
Where it goes: Steel gets melted down and made into new construction materials, car parts, appliances. The recycling process uses 75% less energy than making new steel from ore.
Aluminum — Lightweight Gold
What it is: Lightweight, silvery metal Common items: Soda/beer cans, window frames, siding, car parts, foil, pie tins
Recyclability: Aluminum is infinitely recyclable and highly valuable. Recycling one can saves enough energy to run a TV for 3 hours.
- How to identify:
- NOT magnetic
- Very lightweight
- Silvery color (may be painted)
- Doesn't rust
- Soft — you can dent it easily
Sacramento value: $0.60-0.80 per pound for cans (CRV centers pay more per can). Clean aluminum scrap: $0.40-0.60/lb.
The can game: In California, you get CRV redemption on cans — 5¢ for under 24oz, 10¢ for larger. A pound of crushed cans = about 25-30 cans = $1.25-3.00 depending on where you take them.
Why it's valuable: Making new aluminum from ore is extremely energy-intensive. Recycled aluminum uses 95% less energy, so there's huge demand for scrap.
Copper — The Red Gold
What it is: Reddish-orange metal Common items: Electrical wiring, plumbing pipes, pennies (pre-1982), electronics, old pots/pans
Recyclability: Extremely valuable and in constant demand.
- How to identify:
- NOT magnetic
- Distinctive reddish-brown color (when clean)
- May have green patina (oxidation)
- Found inside electronics, appliances, walls
Sacramento value: $2.50-4.00 per pound (varies with market). THIS IS HIGH.
- Copper grades:
- Bright & shiny copper (bare wire, no coating): Highest value
- #1 Copper (clean, uncoated): Very high value
- #2 Copper (oxidized, painted, attached fittings): Moderate value
- Insulated wire: Lower value (still worth it)
- Where to find it:
- Old extension cords (strip the insulation)
- Gutted appliances (motors have copper windings)
- Plumbing repairs (old copper pipe)
- Electronics teardowns
Important: Don't steal copper. Scrapping stolen wire is illegal and scrap yards check ID.
Brass — The Yellow Alloy
What it is: Copper + zinc alloy Common items: Plumbing fittings, keys, doorknobs, decorative items, musical instruments, ammunition casings
Recyclability: Good value, always in demand.
- How to identify:
- NOT magnetic
- Yellow-gold color (darker than gold, lighter than copper)
- Heavier than aluminum
- Often used for fittings and hardware
Sacramento value: $1.50-2.50 per pound (varies by grade and market).
- Brass grades:
- Yellow brass (keys, fittings): Standard value
- Red brass (valves, high copper content): Higher value
- Plumbing brass (faucets with attachments): Lower value
- Common finds:
- Old door hardware
- Plumbing fittings and valves
- Bed frame decorations
- Fire sprinkler heads
- Lamp bases
The key test: If you have a jar of old keys, that's brass. Scrap yards will buy them.
Stainless Steel — The Tricky One
What it is: Steel + chromium + nickel alloy Common items: Kitchen sinks, cookware, appliances, restaurant equipment, cutlery
Recyclability: Valuable, but you need to know your grades.
The magnet confusion: Some stainless steel is magnetic, some isn't. It depends on the grade.
- Stainless types:
- 300-series (non-magnetic): Contains nickel. Higher value. Used in food service, medical equipment.
- 400-series (magnetic): No nickel. Lower value. Used in automotive, utensils.
- How to identify stainless:
- Doesn't rust (may show discoloration)
- Silvery, shiny surface
- Often stamped with grade (18/8, 18/10 = 300-series)
- Heavier than aluminum, lighter than regular steel
- Sacramento value:
- 300-series (non-magnetic): $0.40-0.60/lb
- 400-series (magnetic): $0.10-0.20/lb
Where to find it: Old sinks, restaurant cookware, appliance panels.
What's Worth Money — Sacramento Scrap Value Guide
Here's what Sacramento-area scrap yards pay (prices fluctuate, these are typical ranges):
| Metal | Value per pound | Why it matters | |-------|----------------|----------------| | Copper | $2.50-4.00 | HIGHEST — worth actively collecting | | Brass | $1.50-2.50 | HIGH — good side income | | Aluminum cans | $0.60-0.80 + CRV | HIGH — easy to collect | | Aluminum scrap | $0.40-0.60 | GOOD — lightweight adds up | | Stainless (300) | $0.40-0.60 | GOOD — if you have quantity | | Stainless (400) | $0.10-0.20 | LOW — but better than trash | | Steel | $0.05-0.10 | LOW — only worth it in bulk |
- Strategy:
- Copper is king: If you're tearing down electronics or doing home repairs, save every bit of copper wire and pipe.
- Aluminum cans pay double: Take cans to CRV centers for redemption value + scrap value.
- Brass fittings add up: That jar of old keys? That box of doorknobs? Worth $20-50.
- Steel in bulk only: Don't drive across town for 10 lbs of steel. But if you're scrapping an appliance? Worth it.
Price tip: Scrap metal prices change with global markets. Call ahead or check scrap yards' websites for current pricing.
