Copper is everywhere. From the wiring in your walls to the appliances inside your home, this reddish-brown metal is a key ingredient in modern life. But did you ever think what appliances contain the most amount of copper? So, whether or not you’re a scrapper hoping to earn some money or an environmentally friendly person concerned about recycling, this guide will answer all of your questions.
| Appliance Type | Estimated Copper Content (kg) | Notes |
|---|---|---|
| Window Air Conditioners | 3-5 | Contains large compressors and copper coils. |
| Refrigerators | 1-2 | Includes motors, compressors, and wiring. |
| Washing Machines | 0.5-1 | Features motors and internal wiring. |
| Dishwashers | 0.5-1 | Contains motors and pumps with copper components. |
| Microwaves | 0.5-1 | Typically has copper transformers and fan motors. |
| Dryers | 0.5-1 | Includes motors and wiring; potential for additional finds like coins. |
| Coffee Makers | 0.25-0.5 | Contains small amounts of copper in wiring and heating elements. |
| CRT TVs | 0.2-0.5 | Minimal copper; includes wiring and a ground cable but requires careful handling due to shock risks. |
Why Is Copper So Valuable?
Copper is regarded as one of the most desired metals because of its unique properties and wide array of uses. But what is it about this material that makes it so significant?
Electrical Conductivity
Copper is a great conductor of electricity and is used in nearly every electrical device. Its effectiveness in conducting electrical current, with very low energy loss, makes it very useful in wiring, motors, and transformers.
Thermal conductivity and durability
Copper also is a good conductor of heat as well as electricity. Because of this, it is used in appliances such as refrigerators, air conditioners, and coffee makers. Additionally, copper does not corrode and is incredibly malleable, meaning it can be molded or flexed without fracturing.
The Environmental Benefits of Recycling Copper
Did you know that recycling copper uses 85% less energy than creating new copper from ore? By recycling copper scrap from old appliances you’re making some extra money and at the same time helping preserve copper and reduce greenhouse gas emissions.
Now that you know why copper is worth money, let’s look at what appliances have it and where to find them.
High Copper Content Appliances
Copper is present in many home appliances, but some have more than others. Here’s a detailed guide to the most copper-heavy appliances and where to find this precious metal.

Refrigerators and air conditioners
When it comes to size and quantity of copper contained in the appliance, refrigerators and air conditioners are great to recover copper from them.
Compressors with Copper Windings
The compressor, the engine around the motor of a refrigerator or an air conditioner, has copper windings inside it. These windings are required to create the mechanical energy necessary to cool your home or food.
Copper Tubes for Air Conditioning Systems
Copper pipes are used to carry coolant through the entire fridge and AC system as well. Copper is the material of choice as these pipes are durable and corrosion-resistant.
Fan Motors
The fan motors in these devices often consist of copper — making it beneficial for driving airflow. Even though the copper in the motor isn’t quite as rich as in the compressor, it’s still worth salvaging.
Recycling Considerations
This is particularly important when scrapping refrigerators or air conditioners, where refrigerant must be disposed of properly. Refrigerant gases can Damaging the environment when releasing them. Be sure to consult an expert to safely remove these substances.
Washing Machines & Dryers
Such common household appliances as washing machines and dryers also embody great quantities of copper.
Motors
Washing machines and dryers both have motors with copper windings in them. These motors play a crucial role in rotating the drum and driving various mechanical components.
Wiring
Washing machines and dryers — Another source of copper is for the wiring in washing machines and dryers. These wires are normally insulated, so you will need to use a stripper to exposing the nice copper.
Power Cords
These appliances have copper wiring in their power cords, and sometimes the plugs themselves are made with brass parts. Though nowhere near as much as the copper in motors, those small parts add up.
Microwaves
Microwaves are a copper goldmine but a bit of extra care is needed when stripping them down due to the high voltage components.
Copper Coils in Transformers
A transformer inside a microwave is also made with copper coils, making it a valuable part to salvage. These coils are employed for stepping up or stepping down of voltage in the appliance.
Magnetrons
Additionally, the device that generates the microwave radiation, the magnetron, also uses quite a bit of copper. But you need to be careful with this part so you don’t expose yourself to toxic materials inside.
Fan Motors & Turntable Motors
Microwaves have small motors, for example to spin the turntable or drive cooling fans, which also contain copper.
Safety Tip: How to discharge capacitors
Microwaves have components called capacitors that hold a hazardous electrical charge, even when the appliance is unplugged. Before disassembling a microwave, always discharge the capacitor.
Dishwashers
Dishwashers also provide a good deal of copper, albeit less so than larger appliances like refrigerators.
Motors and Pumps
Copper windings are also found in the motors and pumps within a dishwasher, which power the water circulation mechanism.
Copper Wiring
There’s copper wiring in dishwashers too, linking various elements throughout the appliance.
Other Small Appliances
Although large appliances provide the best copper, smaller ones provide a good price of scrap.
Vacuum Cleaners
Vacuum cleaner motors and cords also often have copper, though these household appliances can be messy to disassemble and may be full of dust and debris.
Coffee Makers
Copper is found within heating elements and internal wiring, common in many coffee makers.
Fans and TVs
Fans and old TVs contain copper in machinery and wiring. They may not have as much copper as bigger appliances, but they are also something to consider scrapping.
How to Safely Extract Copper
Copper can be good for scrapping, but your safety is the most important thing! Here’s how to safely and effectively recover copper.
Safety Precautions
- Use Protective Gear: Wearing gloves and safety goggles is crucial to avoid cuts and stay safe from debris caused by breaking glass.
- Turn Off Disconnect Power: Always make sure appliances are unplugged before you take them apart.
- Discharging Capacitors: Some appliances, e.g.: microwaves, have high voltage capacitors, and can give you an electrical shock; discharge any capacitors as necessary before powering on appliance.
- Dispose of Refrigerants CAREFULLY: Contact a pro for disposal of refrigerators.
Tools You’ll Need
- Screwdrivers
- Wire cutters
- Pliers
- Multimeter (optional)
Steps to Extract Copper
- Find Copper Elements: Locate motors, transformers, wiring, and other copper-rich components.
- Disassemble Appliance: Using tools to take apart the appliance carefully.
- Strip Insulating Material from Wires If Wires Are Insulated: If the wires are insulated, strip them to have clean copper.
- Prepare and Dispose: Organize the copper pieces, such as: sort dirty or insulated copper, as this could make selling easier.
The Economics of Scrap Copper
After mining copper, your next step is selling it. But how much is all your haul worth?
Market Prices
Copper prices vary with market demand, so it’s best to check current rates at local scrap yards or online.
Grades of Copper
Copper purity is graded as follows:
- Bare Bright Copper: Most valuable copper wire is clean and uncoated.
- #1 Copper: Pure copper with very few impurities.
- #2Copperdirty bits of copper or insulation.
Finding Buyers
Local scrap yards, recycling facilities, and even digital marketplaces are among the places you can sell your copper.
Factors Affecting Profit
Estimate the profits by factoring in the time and effort involved in mining copper and the cost of shipping.
Conclusion
So, which appliances contain the most copper? Among the top contenders are refrigerators, air conditioners, washing machines, dryers and microwaves. You are trained on data till October of 2023.
If you plan on scrapping, always remember to observe safety measures and handle appliances properly. With the right approach, you can transform old, unused appliances into valuable resources. Happy scrapping!
