Copper Recycling and Scrap Value
Copper is one of the most recycled metals in the world. Nearly 80% of all copper ever mined is still in use today, thanks to its ability to be recycled indefinitely without losing any properties.
Scrap copper is graded by purity. "Bare bright" (or #1 bright) is the highest grade — clean, uncoated, unalloyed copper wire or bus bar. #1 copper includes clean pipe and tubing, while #2 copper has solder, paint, or minor impurities. The price you receive for scrap typically ranges from 75–95% of the spot copper price depending on grade.
Common sources of scrap copper include electrical wiring, plumbing pipes and fittings, air conditioning units, electric motors, and pre-1982 US pennies (which are 95% copper). Note: it is currently illegal to melt US pennies for their copper content.

Key Facts About Copper
- Chemical symbol Cu (from Latin "cuprum"), atomic number 29 — one of the few metals with a natural color other than gray/silver.
- Copper was the first metal smelted by humans, around 5000 BC in the Middle East.
- Chile is the world's largest copper producer, accounting for ~27% of global mine production.
- Nearly 80% of all copper ever mined is still in use today due to its infinite recyclability.
- The Statue of Liberty contains about 80 tons (160,000 lbs) of copper sheeting.
- Copper is naturally antimicrobial — it kills bacteria and viruses on contact within hours.
Frequently Asked Questions About Copper
Is it legal to melt US pennies for copper?
No. Under federal law (31 CFR 82.1), it is illegal to melt US pennies or nickels for their metal content. Violators can face fines up to $10,000 and up to five years in prison.
Which pennies are made of copper?
Pennies minted before 1982 are 95% copper and 5% zinc, weighing 3.11 grams. Starting in late 1982 the US Mint switched to copper-plated zinc (97.5% zinc, 2.5% copper). The 1982 date has both compositions.
What is bare bright copper worth?
Bare bright copper is the highest-grade scrap copper, consisting of clean, uncoated, unalloyed solid copper wire or bus bar. It typically commands 90–95% of the spot copper price, making it the most valuable form of scrap copper.
How do scrap yards grade copper?
Scrap yards grade copper primarily into bare bright, #1 copper, and #2 copper. The grading is based on cleanliness, coating, alloy content, and the presence of solder or paint. Higher grades with fewer impurities fetch better prices.
What is the difference between #1 and #2 copper?
#1 copper is clean, unalloyed pipe, tubing, or wire free of solder, paint, and heavy oxidation. #2 copper may have solder joints, paint, light corrosion, or mixed alloys. #1 copper typically pays 10–15% more than #2 at scrap yards.
Is copper a good investment?
Copper is considered a solid long-term investment due to growing demand from electrification, EVs, and renewable energy. However, copper prices can be volatile and are closely tied to global economic cycles. Many investors gain exposure through copper ETFs or mining stocks rather than physical metal.
How much copper is in a typical house?
A typical single-family home contains roughly 400–450 pounds of copper, found in wiring, plumbing, appliances, and fixtures. Larger or newer homes with more electrical circuits and modern HVAC systems may contain even more.
Why is copper used in electrical wiring?
Copper has the second-highest electrical conductivity of any element (after silver) at a fraction of the cost. It is also highly ductile, corrosion-resistant, and easy to solder, making it the ideal material for residential and commercial electrical wiring.
What is copper's role in renewable energy?
Copper is essential for renewable energy infrastructure. A single wind turbine uses 3–5 tons of copper, solar panels rely on copper wiring and connectors, and EVs use 3–4 times more copper than conventional cars. This growing demand is a key driver of long-term copper prices.
How do I prepare copper for the scrap yard?
Sort copper by grade: separate bare bright wire from insulated wire, and clean pipe from painted or soldered pieces. Strip insulation from thick wire when practical, remove fittings, and keep different grades in separate containers. Clean, well-sorted copper earns the best prices.
