Is It Worth Melting Down Aluminum Cans?

Recycling aluminum cans by melting them down into ingots or scrap aluminum may seem like an easy way to earn extra cash.

However, before you fire up that backyard furnace, it helps to weigh the pros and cons to decide if DIY aluminum recycling is truly worth the effort.

If you’re short on time, here’s a quick answer: Smelting aluminum requires specialized equipment and involves several hazards, so for most people, it’s not worth the effort compared to just bringing cans to a local recycling center.

Pros of Melting Aluminum Cans

Higher Market Value for Scrap Aluminum Compared to Recycling Whole Cans

Melting down aluminum cans can be a worthwhile endeavor due to the higher market value of scrap aluminum compared to recycling whole cans.

When aluminum cans are recycled, they are typically crushed and baled together with other materials, such as plastic and glass.

This mixture of materials makes it more difficult to separate and process the aluminum, resulting in a lower value for the recycled cans.

On the other hand, melting down aluminum cans allows for the extraction of pure aluminum, which has a higher market value. The process involves melting the cans at high temperatures to separate the aluminum from any impurities.

Once the aluminum has been melted and purified, it can be sold to metal recyclers or manufacturers who use it to create new products.

According to a study conducted by the Aluminum Association, the average price for recycled aluminum cans was around $0.50 per pound, while the price for scrap aluminum was approximately $0.70 per pound.

This significant difference in price demonstrates the financial benefits of melting down aluminum cans.

Satisfaction from Turning Trash into Treasure

Another compelling reason to melt down aluminum cans is the satisfaction that comes from turning trash into treasure.

By taking the time to collect and melt down aluminum cans, individuals can actively contribute to reducing waste and conserving resources.

When aluminum cans are melted down, they can be transformed into new products or raw materials for manufacturing.

This process not only saves energy and resources but also helps to reduce the demand for newly mined aluminum, which has a significant environmental impact.

Melting down aluminum cans also provides an opportunity for creativity and craftsmanship. Some individuals enjoy using molten aluminum to create unique, handcrafted items such as jewelry, sculptures, or even furniture.

This allows for a sense of personal fulfillment and satisfaction in repurposing materials that would otherwise end up in landfills.

Cons of Melting Aluminum Cans

Dangers from Molten Aluminum and Toxic Fumes

Melting aluminum cans can be a hazardous process due to the dangers associated with molten aluminum and toxic fumes.

When aluminum is heated to its melting point, it becomes a liquid that can cause severe burns if it comes into contact with the skin.

Additionally, the fumes released during the melting process can contain harmful gases, such as aluminum oxide, which can be harmful to inhale.

It is important to take proper safety precautions, such as wearing protective clothing and working in a well-ventilated area, to minimize these risks.

Specialized Equipment Needed

Melting aluminum cans requires specialized equipment that may not be readily available to everyone.

A crucible, which is a container made of heat-resistant material, is needed to hold the molten aluminum.

A furnace or kiln capable of reaching temperatures of around 1220°F (660°C) is also necessary to melt the aluminum cans.

These pieces of equipment can be expensive to purchase or rent, making it a barrier for individuals who are interested in recycling aluminum cans at home.

High Energy Costs

The process of melting aluminum cans requires a significant amount of energy. The furnace or kiln used to melt the cans needs to reach and maintain high temperatures for an extended period of time, resulting in high energy costs.

This can make it less cost-effective to melt aluminum cans at home, especially for individuals who are looking to save money on their recycling efforts.

It is important to consider the energy consumption and associated costs before deciding to melt aluminum cans.

Time-Consuming Process

Melting aluminum cans can be a time-consuming process, especially when working with limited equipment or small quantities of cans.

It takes time for the furnace or kiln to heat up to the required temperature and then additional time for the cans to melt completely.

Furthermore, the molten aluminum needs to be properly cooled and solidified before it can be handled or used for other purposes.

This can be a time-consuming task, which may not be feasible for individuals who are looking for a quick and efficient way to recycle their aluminum cans.

Tips for Melting Aluminum Safely

Use Proper Protective Gear

When melting aluminum, it is crucial to prioritize safety. Wearing the appropriate protective gear will prevent any accidents or injuries.

It is recommended to wear heat-resistant gloves, safety goggles, and a long-sleeved shirt to protect your skin from possible splashes or burns.

Additionally, using a respirator or dust mask will help you avoid inhaling any harmful fumes or particles during the melting process.

Proper Protective Gear

Work Outdoors with Good Ventilation

Melting aluminum can release hazardous gases and fumes, so it is best to perform this activity outdoors or in a well-ventilated area.

Adequate ventilation will help disperse any potentially harmful gases, ensuring a safer environment for you and those around you.

If you have a dedicated outdoor space for melting aluminum, it is highly recommended to use it to minimize any potential risks.

Invest in Quality Crucibles and Molds

The quality of the crucibles and molds used in the aluminum melting process can greatly influence the outcome.

Investing in high-quality crucibles made from materials such as graphite or ceramic can withstand high temperatures and provide better heat distribution, resulting in more efficient melting.

Similarly, using reliable molds that are specifically designed for aluminum casting will help you achieve better results and reduce the risk of defects in your final products.

It is worth mentioning that while melting aluminum cans can be a worthwhile endeavor, it is essential to follow safety guidelines and take necessary precautions.

By using proper protective gear, working in a well-ventilated area, and investing in quality crucibles and molds, you can enjoy the process of melting aluminum while ensuring your safety.

Compare Scrap Prices at Local Recycling Centers

When it comes to recycling aluminum cans, one of the most important factors to consider is the price you can get for your scrap.

Different recycling centers offer different prices, so it’s worth doing a bit of research to find the best deal in your area.

Recycling Centers

Why should you compare scrap prices?

Comparing scrap prices at local recycling centers allows you to maximize your earnings. Just like any other market, the price of aluminum fluctuates based on supply and demand.

By shopping around and comparing prices, you can ensure that you get the best possible return for your recycled aluminum cans.

How to compare scrap prices

Start by calling or visiting multiple recycling centers in your area.

Ask them about their current prices for aluminum cans and any other relevant information, such as whether they require cans to be sorted or crushed. Keep a list of the prices you are quoted so that you can compare them later.

It’s also worth checking online resources that provide information on scrap prices in your area.

Websites like or iScrap App aggregate data from different recycling centers and can give you an idea of the average prices in your region.

Factors to consider when comparing prices

While the price per pound is an important factor, there are other factors to consider as well. Some recycling centers may offer additional incentives or bonuses for frequent customers or larger quantities of cans.

Others may have more convenient hours or better customer service. Take all of these factors into account when comparing prices.

Pro tip: Don’t forget to factor in the cost of transportation. If one recycling center offers a slightly higher price per pound but is located farther away, you may end up spending more on gas than you earn in extra profit.


Before deciding to melt aluminum cans, carefully weigh the dangers and costs versus potential profits.

Most people will likely find it’s not worth the hassle for small quantities of cans.

However, as an educational hobby or for larger recycling operations, melting cans into ingots or scrap may pay off. Be sure to take all safety precautions when working with molten aluminum.
