Do Metal Detectors Detect Aluminum?

People often wonder do metal detectors detect aluminum because aluminum is commonly found in trash, and so they want to consider whether or not it will impact their goal of treasure hunting, as no one wants to collect trash.

Many people, especially beginners, want to know what the metal detector can detect. They were told that the detectors could detect all types of metals, including ferrous and non-ferrous. People may become confused about do metal detectors detect aluminum.

Why People Are Worried About: Do Metal Detectors Detect Aluminum Or Not?

It is often a matter of concern why people show interest when it comes to the detection of aluminum. So, here are a few possible reasons that could drive the users or the detectorists to know about this fact.

Abundance Of Aluminum In Trash

People are curious about detecting aluminum with metal detectors because it’s often found in trashy areas.

Aluminum is found in items like bottle caps, can seals, packaging material, foils, medicine cases, and other similar stuff.

This stuff is somehow considered to be useless, and the frequent presence and detection of it frustrate hobbyists. That is why they often show concern regarding this fact.

Aluminum Is Less Conductive

But aluminum is also a non-magnetic metal with low conductivity, like gold. So, when aluminum is detected, the metal detector detects it as gold and not aluminum, due to the resemblance in composition and category.

It can be frustrating for the user if they search for objects and find aluminum items like wrappers or bottle caps. This can make them lose interest in the hobby.

Manufacturers Do Not Mention Aluminum

Metal detector companies promote the ability of their detectors to find valuable metals, but not aluminum. This raises concerns about their ability to detect aluminum.

So, this point clicks in the minds of the operators and users, leading to confusion and multiple questions regarding the cause.

Which Metal Detectors Detect Aluminum?

Overall, every detector is capable of detecting aluminum. However, older detectors, such as those designed for children and beginners, may not detect aluminum.

These detectors may also miss significant metals. Any decent metal detector will work to collect aluminum scraps for recycling or selling.

Features Required To Detect Aluminum

Detectors With High Frequencies

Now, let’s think about which metal detectors are best for detecting aluminum. Experts suggest using a metal detector with a high-frequency range to find aluminum.

Aluminum is non-ferrous, like gold, so it lacks magnetic properties. That’s why it’s hard to detect. To detect aluminum easily and with less frustration, a high-frequency range detector can be used for deep detection and penetration.

Detectors With Gold And Non-ferrous Discrimination

Metal detectors have another feature: they can distinguish between gold and non-ferrous metals. This feature helps users choose which metals their devices will detect, such as aluminum, gold, or others.

Detectors Intended For Coins And Relics

In addition to the frequency option, gold or non-ferrous discrimination features are important. Another prominent feature is the use of metal detectors for coins and relics.

This is because the aluminum items are usually of the same size and measurements as the coins and relics. 

For example, bottle caps could be mistaken for coins, and water bottles could be included in relics in the field of metal detection. So, utilizing detectors specified for gold, relics, or both could serve the purpose equally.

What Aluminum Items Could Be Detected?

The aluminum products that could be detected with the help of a metal detector are as follows.


Foil is termed as an aluminum product that can be detected with the help of a metal detector. Foil is present in the form of compressed and plain sheets.

The aluminum product is not very valuable and costly but could benefit you in the processes of reuse and recycling. These foils are then converted into soft sheets, which are then further used in kitchens, salons, and as packaging material.


Another form in which aluminum could be detected is tins made up of thin aluminum sheets. The seals of these tins are frequently detected and are present on the underground surface in abundance.

The cans are made from thin foils and sheets, so they are lightweight and easy to shape. They can be reused and recycled.

Other Necessary Components

All detectors can find aluminum, but they need specific frequency and discrimination settings. It could easily be reused and recycled as it is made up of light material, so it is easy to break and convert.

Raw aluminum can be used to shape various accessories, including packaging materials, window frames, and electrical appliances.


When people choose a device, they often have two main concerns. Some want to avoid aluminum because it isn’t valuable. Others want a device that works well with aluminum and other materials.

However, before reaching this stage, the matter of concern for all is, do metal detectors detect aluminum. The simple and easy explanation for this is yes, metal detectors have the capacity and capability to detect aluminum.

So if you metal detecting with the purpose of collecting aluminum, you can get metal detector that can detect aluminum rather easily. But if you are hoping to avoid the detection of aluminum and are getting into metal detecting as a hobby for treasure hunting then you will need a metal detector with the capability of discrimination.

With a metal detector in discrimination mode, you can avoid detecting useless trash and only detect gold.
