Does super glue work on metal

Superglue helps to form strong bonds/repair many substances like metal, rubber, and plastics. They are fast-bonding, high-strength materials which can fix almost any available material. Furthermore, superglue is waterproof, but it still has some declination on this point & that is, it cannot be waterproof for longer.

You must be wondering, Is superglue that strong?

Yes, it certainly is, as many researchers gave their efforts to develop this thing. Superglue is one one the strongest glue that one can choose to repair things. 

More likely, it is hard to believe that superglue works on metal; the answer is still positive as superglue shows a great bond on metals and fixes them & gives them a new look.

How Super Glue Works on Metal?

Super Glue works on metals by first making a chemical bond between the two things. The strength between them depends on a few things, like the type of metal used, the surface preparation, and the amount of glue used. A cyanoacrylate molecule in the glue creates the bond after the molecule in the glue reacts with the air’s moisture. In simple terms, if the glue gets exposed to the air, then the glue’s ability to strengthen/rejoint something will not be the same & will certainly decrease. 

Benefits of Using Super Glue on Metal

There are various benefits of using Superglue on metal, and some of them are:

Fast Drying

More likely, super glue is a Fast drying substance as it is just a matter of time (a few minutes) to make it dry, making it strong. Although the time also depends on the type of metal & the glue used. This fast-drying feature is one of the best options for quick repairs, as you don’t have to wait longer. 

Strong Bond

Superglue is a cyanoacrylate adhesive that creates a strong bond between the metal surfaces. It has numerous features like fast-drying, strong bonds, and many more, which can bond almost every material.

Easy To Use

Although it has many benefits, it is still very easy to use. You should add a small portion of the glue to the metal surfaces you want to join. After adding the glue to the surfaces, hold the glue for a few seconds so that it will get dry. It does not require any skills to do these steps.

Step-by-Step Guide – How to Use Superglue on Metal

Below mentioned are the proper steps to apply/use superglue on metals.

Step 1- Cleaning the surfaces is necessary as it will help the glue create a strong bond by excluding the dust on the surfaces. You need to clean the metal surfaces first & make them dust-free, which you want to join. You can use items like alcohol or acetone to remove any dirt, oil, or grease present in there. 

Step 2- You don’t need a large amount of glue as it is just a matter of a small amount to fix the metal surfaces with a strong bond. As a superglue can cause harm to a human body, you should use a toothpick or needle to apply the glue. It would be more precise too by using this way.

Step 3- To strengthen the bond, make sure to get a hold of them properly. You just need to hold both metal surfaces for a few seconds to make sure that the two metal surfaces join together. This process will help the glue to set properly & effectively.

Step 4- You need to be patient before ensuring that the glue gets adequately dried before you use it. As it is just a matter of an hour to use your metal flawlessly, you need to show a bit of patience. 

Some additional tips for using the super glue on the metal

Additionally, a few tips for using the super glue on the metal properly are:

  1. You need to use a high-quality superglue that is specially designed for metals.
  2. Don’t add too much glue to the material, as it weakens the bond. You can use a small amount of glue as it will make the bond stronger than the previous one. 
  3. To make the glue to be set, you need to hold the surfaces for at least 50-60 seconds.

Testing the Adhesive Ability of a Super Glue on Different Types of Metal

Check out below:


You need some materials, to begin with, and they are :

  1. Varieties of metals like steel, aluminum, copper, and brass
  2. Super glue
  3. Adhesive tape
  4. A saw or other cutting tool
  5. A scale
  6. A force gauge


  1. You must cut the metal pieces into smaller sizes(1-inch cubes).
  2. Measure the weight of every metal piece. 
  3. Add a small amount of glue to one side of each piece.
  4. Hold the pieces for a few seconds to set the glue properly. 
  5. Use a force gauge to measure the force, i.e., required to pull the pieces of metal apart.


This experiment shows that super can bond with different types of metals. We’ve also figured out that the force required to pull the pieces of metals apart will be higher for the metals strongly bonded with the super glue.

The Limitations of Superglue On Metals

There are several limitations of using super glue, which you need to look at before you use it for your personal purpose. 

Some limitations are:


The bonds made by the superglue are brittle. Simply put, the bond made through super glue can easily break if you apply some force to it. This thing is essentially positive if both surfaces are not properly fixed.

Poor peel strength

The bonds made by the superglue have poor peel strength. Simply put, they are not good at resisting the forces that try to peel the two surfaces apart. This can be the problem if the substance gets subjected to more & more peeling forces.

Limited gap filling

As the metal, i.e., is broken and after glueing, it does not fill the gaps. So if you’re looking forward to using superglue for repairing surfaces that have large gaps, you shouldn’t use them as it does not work perfectly in this case.

Low-temperature resistance

Superglue bonds can become brittle if subjected to low temperatures, so it is bad to repair metal objects while it remains exposed to cold weather.

Susceptibility to chemicals

The glue can get damaged by the chemicals. Using chemicals for such metals that will be exposed to chemicals is not preferred.

Precautions While Using The Superglue 

There are many things you need to keep in mind while you’re using superglue on the metals. The things are:

  1. Super Glue can be harmful if they get into your eyes/your skin. You need gloves & eye protection on your skin and tooth sticks or needles while applying the glue.
  2. As super glue dries very fast, you need to complete your work very quickly & carefully.
  3. You can try removing the glue with acetone or rubbing alcohol if any mistake happens. However, it is not possible to obliterate the glue.

Final Thoughts

Hence, it is clear that superglue does work on metals & can create a strong bond between the metal surfaces. Using super glue can be very fast-drying, easy to use, and be used in an excellent way to make fast repairs. However, there are also certain limitations, such as brittleness, poor peel strength, limited gap filling, low-temperature resistance, and susceptibility to chemicals, as mentioned in this article.
