Can Metal Detectors Detect Aluminum? Complete Guide

Can Metal Detectors Detect Aluminum?

The question of what kinds of elements a detector could detect is likely to be asked by the public. A metal detector, as its name suggests, is typically thought to be able to identify every metal. Can metal detectors detect aluminum?

Can metal detectors detect aluminum? Yes, in a nutshell.


It’s a common misconception that aluminum cannot be found since it is non-ferrous. This is untrue, given that aluminum is electrically conductive and can thus be easily found. Aluminum can be detected by the majority of detectors only when the parameters are correctly tuned. In practice, you’ll have to have a detector with adjustable resistivity sensors.

What Kinds of Metals are able to be Identified by Metal Detectors?

The most common metals in an environment that may be found are three different sorts. Such sensors were capable of detecting the following metals.

Ferrous Metals

The two most typical types of ferrous metals include steel as well as cast iron. If they get near sufficient, almost each has the ability to be drawn to magnetic objects. Because of their large voltage permeability, this class of elements is well recognized for making them simple to detect.

Non-Ferrous Metals

When contrasted to ferrous metals, such are indeed the metals that seem to be applicable to commerce and have a higher price. Non-ferrous metals include zinc, brass, silver, as well as gold. In comparison to metallic materials, such metals lack magnetic characteristics and are more difficult to detect.

Recent advancements in metal detector technology have made it possible to identify these materials as quickly and reliably as ferrous metals. Other non-ferrous metals include aluminum.

Steel is Stainless

It was just one of the least electrically conductive metals, making it one of the most challenging to locate while metals detectors. Tools, cookware, and vehicle components are among the items that use these metals.

Can Metal Detectors Detect Aluminum?

The answer is unquestionably affirmative, notwithstanding the misleading data that is currently accessible about aluminum foil with metal detectors. Aluminum foil may be found with metal detectors.

The misconception that this specific metal could avoid detection by the majority of metal detectors has gained widespread traction. Aluminum is indeed a non-ferrous metal. However, despite this, it is electrical and, therefore, will trigger the majority of metal detectors. In reality, as far as even just a small amount of metal present, a metal detector could find almost anything.

Simply put, walk-through metal sensors are now more robust and spacious hand-held metallic detectors similar to those you would see at public events. However, due to their size, walk-through metal detectors may more easily find tiny particles of aluminum foil as well as other elements.

Why does Aluminum Cause Problems with Metal Detection and Identification?

Aluminum would be a non-ferrous material. Therefore, that is probably why.

Aluminum would be more prevalent than some other non-ferrous metals since it is available in significant amounts in the environment as a result of cans, cookware, and other items. Therefore, it is likely that you will be able to locate non-ferrous elements in the background more frequently than every other element.

The problem can be resolved by adjusting the metallic detector’s settings to separate large and tiny aluminum objects. Aluminum is, therefore, neither the hardest nor the easiest noticeable material, as you might have noticed. It resides in the middle.

Which Elements Could Influence How Well Aluminum is Detected by Metal Sensors?

When utilized for aluminum identification, a metallic detector’s performance may be impacted by a number of circumstances.


The temperature comes #1 on the list. Metals frequently experience thermal expansion and thermal contraction. The variation is insignificant at room temp, whereas when a metallic detector is utilized in an environment with severe temps, the capacity to detect metal may be compromised.


Density also has an impact on a metal detector’s capacity to identify aluminum. The strength of an object’s magnetism will typically increase with size and thickness.

Additionally, when metal detectors when utilized in locations with significant concentrations of magnetite, a material containing iron oxide, devices may provide misleading indications for aluminum. Multi-frequency detection systems are capable of identifying aluminum from the soil below the surface.

Soil Makeup

The makeup of the ground is yet another element that influences if aluminum may be found using a detector. There is aluminum present because clay soil transmits electricity better than fine sand. More frequently than in typical soil made of fine sand, it is present in clay soil.

Aluminum Specific Metal Detector Presets

In marketplaces, the majority of metal detectors have unique features. Adjustments and characteristics in sensors can be made in accordance with aluminum. There are at least three different configuration options included with each detector, allowing you to set them up as needed.

One might run into a lot of issues when using metal detector equipment for aluminum since it produces more signals than other metals do. It is challenging to look for certain things since there are so many aluminum metal pieces in our environment, all in separate segments and dimensions.

The detector needs additional capabilities to pick out desired things among tiny ones and to save energy, preventing the use of such useless items.

What Metal Detectors Should You Use to Find Aluminum?

You need to take into account what kinds of metals you are looking for when choosing which detector to buy in your search for aluminum.

Others can merely detect changes in conductance, while sure detectors are made to distinguish between two different metals even if they share a similar permeability.

It could be advisable to spend money on such a metal detector explicitly made for locating non-magnetic materials if the item you’re seeking is neither magnetic nor more conductive than some other metals found in the earth, such as iron.

Buying another all-sensor could be more advantageous if all you need is a metal detector that can only sense aluminum. The changes in conductivity may be picked up by an all-metal sensor, which enables you to begin searching for aluminum as quickly as it is found.
