Copper is broadly categorized by how it is refined, its structural shape, or its plumbing grade. The three most common types of copper pipes used in residential and commercial applications are Type K, Type L, and Type M.
Grade 1 (A) Copper is the highest quality copper. It's 99.9% pure, and is used in electrical applications where high conductivity is required. Grade 2 (B) Copper is 99% pure, and is used in applications where a higher level of ductility is needed.
The spot price for raw copper is approximately $6.25 to $6.38 per pound.
Low–grade #2 insulated copper wire: Found in items such as appliance cords and telephone wire, low-grade #2 insulated copper wire is the most common and consists of unalloyed wire that contains less copper to recover than high-grade wire and typically has some type of tarnish on the bare wire.
the way it is with insulation, that would translate in to $130.00 for your 100lbs of 12-gauge wire, without stripping it. If you were to strip it, your 75lbs of copper would bring you $1.90 per pound $142.50 the difference between stripping and selling it the way it was would be $12.50.
Copper hit its all-time high on January 29, 2026, when the three-month London Metal Exchange (LME) copper price briefly spiked to $𝟏𝟒,𝟓𝟐𝟕.𝟓𝟎 per metric ton (equivalent to roughly $𝟔.𝟓𝟖 per pound).
"Dirty copper" is a scrap metal term for unalloyed copper that contains minor contaminants or attachments (like solder, paint, brass fittings, or light oxidation). While still highly recyclable and mostly pure, it requires extra processing at the foundry, which lowers its value compared to clean copper.
Copper is the leading choice in scrap metal values today. In early 2026, current prices for premium grades have surged well past $4 per pound, making it highly lucrative for waste management operations.
No, a magnet will not stick to pure copper because copper is not ferromagnetic. While copper does not show attraction to magnets like iron or steel, it is a diamagnetic material that can cause weak repulsive forces or drag effects (eddy currents) when a strong magnet is moved near it.
Brass describes a copper alloy that contains zinc, and it's because of this that brass is regularly mistaken for copper. On top of this, brass can also contain metals such as manganese, silicon, lead, aluminium, iron, and tin.
Only thick wire (10-gauge or larger) like Romex, THHN, and industrial cables (e.g., 500 MCM or bigger) is worth stripping. Stripping thin, low-yield cords (like extension cords or appliance cables) takes too much time for very little payout, and they are better sold as insulated wire.
This trend is driven by the belief that copper's value will continue to rise, making it a profitable asset to hold onto. As a result, large quantities of copper, especially in the form of scrap metal, have been stockpiled, creating shortages in the market.
Pure copper is a distinct reddish-orange or reddish-brown metal. When it is freshly cut or unoxidized, it can also appear to have a bright pinkish hue.
Choose Type L copper pipe for the best long-term reliability in your home water supply. It features thicker walls than Type M, making it significantly more durable and better equipped to handle fluctuating water pressure, temperature changes, and corrosion from mineral-rich water.
Vinegar acts as a highly effective, natural cleaning and polishing agent for copper. The acetic acid in vinegar reacts with copper oxide (the dark or green tarnish) to dissolve it, restoring the metal’s bright, shiny appearance.
Yes, you can use WD-40 on copper. It is safe to use as a WD-40 metal cleaner and moisture displacer. It will not chemically corrode the metal, and it is frequently used to remove surface grime and lift oxidation.
Arizona: The Copper State
Arizona rightfully claims its nickname as "The Copper State," dominating U.S. production with an impressive 700 million pounds annually, representing approximately 71% of all domestic copper production.
The global price of copper is approximately $𝟏𝟑,𝟓𝟎𝟎 per metric ton. Prices vary slightly depending on the benchmark:
Whether scrap copper prices will go up in 2026 depends on ongoing market volatility.
Yes, mild dish soaps like Dawn are safe for cleaning copper. Use warm water and a soft cloth or sponge to wash away oils and everyday grime. For deeper tarnish, follow up with specialized copper cleaning methods, but always start gently to avoid damaging delicate finishes.
To make $100 from scrap aluminum, you need anywhere from 55 to 200 pounds, depending on your local scrap yard’s payout rate.
Key Takeaways
Copper pennies are worth more than one cent because of the high price of copper metal. It's illegal to melt pennies, so collectors save them hoping they’ll be worth more in the future. The U.S. might stop making pennies due to cost, which could make melting them legal.
