Copper wire for scrap is a term primarily used to identify copper wire that has already been used, often from copper-containing cables and components that have been salvaged from discarded or retired electronic devices or machinery.
This type of wire has become quite valuable due to the rising price of copper and its relative scarcity. Recycling copper is also beneficial for the environment, as previously mined ore must be processed to create the metal.
Copper wire for scrap usually comes in varying sizes and condition – ranging from heavily corroded and twisted pieces to nearly new condition coiling wires. It can be found in the form of household cables, power cords, electronic devices, electrical motors, and plumbing components.
Collecting and recycling such wires can be profitable and allows you to do your part in sustainability.

What copper wire is worth stripping?
The type of copper wire that is worth stripping largely depends on the quality and quantity of the wire, as well as the current market prices for scrap metal. Generally, any type of insulated copper wiring, including THHN, XHHW, Romex, and others, can be a worthwhile endeavor.
Thicker wires are generally more valuable because they may contain higher concentrations of copper – but this also means they can be more difficult to strip. The length of the wires can also influence their value.
Wires that are 12 to 18 inches in length are usually not worth the effort to strip, while those that are a few feet long or longer can be worthwhile. Additionally, different types of wires may require different tools or techniques to strip them down.
Ultimately, doing some research into current metal prices and the particular type of copper wiring you have can help you determine if it is worth stripping.
What’s the difference between #1 and #2 copper wire?
#1 and #2 copper wire are both unalloyed copper wire, but there are a few fundamental differences between the two. #1 copper wire is a solid copper wire with no other alloys or materials mixed in. It has a maximum conductivity of 100% IACS and is a preferred choice in many applications.
#2 copper wire has some traces of other metals or alloys, typically up to 0. 5%. These alloys can lower the overall conductivity of the wire by up to 6-15%. Despite this, #2 copper wire is still widely used across many industries, due to its reduced cost.
The other major difference between #1 and #2 copper wire is in terms of reselling. #2 copper wire cannot be generally recycled for a profit, since the alloys and materials can no longer be separated.
How much is copper wire worth per pound?
The price of copper wire per pound depends on a number of factors, but as of August 2020, copper wire is selling at around $2. 50 to $3. 00 per pound. The price of copper wire can fluctuate, depending on fluctuations in the metal markets, changes in supply and demand, and even geopolitical factors.
It is also important to remember that the price of copper wire may vary depending on the type, gauge, and quality of the material. For example, thicker gauge and higher-quality copper wiring may sell for higher prices than thinner gauge and lower-quality wiring.
Additionally, colored wire is worth more than standard copper, virgin copper is worth more than recycled copper, and the market value can also change depending on where you buy the material.
What does number 1 copper wire scrap look like?
Number 1 copper wire scrap typically consists of clean, uncoated, unalloyed copper wire and cable, not smaller than 16 gauge. Copper wire inside a 2-inch diameter, and greater, can be stripped of its covering to be used as number 1 copper.
This type of scrap metal is typically free of corrosion and should not consist of water faucets, brass fittings, soldering tips, torches or other non-copper items. Copper wire lugs, thermocouples and solenoids are considerered to be acceptable when separated.
As mentioned above, the copper should not be smaller than 16-gauge thick. Depending on its size and condition, it can vary in color from the traditional red copper to black, green, and yellow tints. Copper #1 wire should have strands in its natural round shape, not flattened or elongated.
What does 3 wire system mean?
A 3 wire system is a power distribution design that involves three electrical wires connecting a common source. The three wires provide the energy needed to power the system, but they are also divided into distinct circuits to safely allow the power to be dispersed from the source and to the individual components of the system.
In the 3 wire system there is a single “hot” (black) wire, a neutral (white) wire, and a ground (bare) wire. The hot wire carries the electrical current from the service panel, then through the switch and to the electrical device or load.
This is the single wire that has the potential for electricity to be transferred from the service panel to the outlet or load.
The neutral wire helps in the transfer of electricity from the switch to the device or load, and shall remain electrically neutral at all times, regardless of the state of the switch. This is also the wire that returns current back to the service panel.
The ground wire is connected directly to the service panel, thus providing a pathway for electricity to safely travel in the event of a short circuit or a fault condition.
In general, 3 wire systems are less complicated and safer to install than other systems since they are inherently more protected due to the presence of the ground wire. They also offer the flexibility to install additional circuits, as the current is returned on the neutral wire.
Where is the place to steal copper?
Stealing copper is a form of theft, and is illegal in most places. While some individuals still attempt to take copper from private properties, there is no safe and legal place to steal it. Copper can be found in many places, in everything from plumbing and wiring, to radios and sculptures, but stealing it is still considered a crime.
To avoid any legal implications, copper should always be purchased from a legitimate seller. There are numerous retailers online, as well as local stores that specialize in copper products. Additionally, many scrap yards also offer copper for sale.
How do you strip large gauge wire for scrap?
Stripping large gauge wire for scrap involves cutting the insulation off of the wire to expose the copper and other metals contained inside. To do this, there are a few methods you can use.
The first method is to use a wire stripping machine. This is a manual or electric machine which is designed to quickly strip the insulation off of a variety of gauges of wire. It works by having adjustable blades which cut through the insulation and then remove it by clamping onto it and pulling it off the metal conductor.
Another method is to use a pair of scissors or wire cutters to snip off the wire insulation. This method is suitable for small diameters of wire and can be done in a few minutes. However, it may take longer for larger gauges of wire which will require more cutting.
Alternatively, you can use a rotary tool such as a Dremel to very quickly cut through the insulation. This should only be done by those who are experienced and familiar with the use of rotary power tools.
Whichever method you choose, make sure you are always wearing the appropriate protective gear and safety glasses. Wire Stripping can be very dangerous and it is important to be careful and aware of your surroundings at all times while performing this task.
How much can you get from selling a pound of copper?
The price that you can get for selling a pound of copper can vary depending on current market conditions. Copper typically trades at a price around US$3/lb. On average, you can expect to get anywhere from US$2.
5/lb to US$3. 5/lb. However, depending on where you live, fluctuations in market prices, available buyers, and the current demand, you may get more or less. Additionally, many scrap yards and metal buyers weigh the copper by pound and then subtract a fee based on what it would cost them to process it, so it’s possible that the price you receive will be lower than the market rate.
It’s best to shop around and compare prices if you are looking to sell.
How many 95% copper pennies are in a pound?
There are approximately 168 95% copper pennies in a pound. As a standard U. S. penny weighs 2. 5 grams, and a pound is equal to 453. 59 grams, the answer would be calculated as follows: 453. 59 grams / 2.
5 grams/penny = 181. 4 pennies. However, since 95% copper pennies contain a mix of copper and zinc, their weight is slightly less than regular pennies, so the actual number of 95% copper pennies in a pound would be rounded down to 168.
What is the highest scrap copper price?
The highest scrap copper price varies depending on the market, but generally the prices for scrap copper range from about $2 per pound to about $4. 50 per pound. The price for scrap copper is mainly based on the quality of the product and the current market price.
Factors that influence the market price of scrap copper include a variety of economic and political factors, including the supply and demand for copper in the marketplace, the economic and political stability of producing countries, and the amount of energy and labor required to mine, process, and manufacture copper products.
Additionally, the current global price of raw copper can affect the value of scrap copper, especially if the scrap copper is contaminated with other materials and chemically altered.
How many feet of copper does it take to make a pound?
It takes approximately 11,182 feet of copper wire to make a single pound of copper. This is because copper has a density of 0. 323 pounds per cubic foot. To calculate the amount of copper wire needed to make a pound you need to multiply the density of copper (0.
323) by the volume of a pound (8. 2 cubic feet). The result is 11,182 feet. Copper is a very popular material for electrical wiring, plumbing, roofing, manufacturing, and more. It is also used for many commercial applications, such as coins and jewelry.
What does 500 feet of copper weigh?
The exact weight of a 500 foot length of copper will depend on the specific dimensions and alloy of the copper material. Generally speaking, pure copper weighs around 8. 92 lbs per cubic foot, so a 500 foot length of copper would weigh around 446 lbs.
However, if the copper has been alloyed with other metallic elements, such as zinc or tin, the weight can increase significantly. Additionally, the thickness and diameter of the wire will also factor into the weight, as a larger wire will weigh more than a thinner wire.
To get an accurate weight for your specific piece of copper, you’ll need to obtain its exact dimensions, alloy composition, and total length.
