Aluminum is widespread because it is quite durable and resistant to external influences. Aluminum has a number of characteristics that make it particularly difficult to bond using standard adhesives. The metal is covered with an oxide film that reliably insulates its surface from external influences, and in addition, it has extremely low porosity. These two properties considerably complicate the handling of aluminum elements. Therefore, when working with this metal, a lot of strong adhesives be powerless here, unfortunately.
If you still need to bond aluminum surfaces, you will have to look for a special glue. Unlike other adhesive mixtures, its composition is supported with special additives. And their task is to prevent the formation of an oxide film on the metal surface.
Joining aluminum surfaces with an adhesive at home is much easier than welding and, therefore, more commonly used. In order to successfully glue metal surfaces, you will need sandpaper, a special compound, and a degreasing agent (as a rule, acetone works well for this purpose).

Experts tips:

  • Aluminum surfaces will be firmly glued together by a two-component adhesive based on epoxy resin. But if it is required to join the surfaces made of aluminum alloy, then it is better to find a glue containing methyl acrylate.
  • For aluminum, only a special glue containing acids and alkalis is suitable. These components provide a degradation of the oxide film, which significantly improves the adhesion of the metal parts.
  • The use of adhesives based on the epoxy resin is strictly prohibited if, in the future, the product will be used for storing drinking water and food or will be in contact with them.
  • The means used for gluing aluminum do not provoke metal oxidation, unlike gas welding. As a result, the repaired product will last much longer. Another benefit of gluing is its low cost.

In this article, we will talk about the five best types of glue that can be successfully used for bonding aluminum surfaces.


E6000 Craft Adhesive –super-strong repair assistant

Buyer’s Guide

Gluing any metal is a very difficult process, and aluminum is not an exception. In order for the joint to be strong and durable, it is important to choose the right glue. The process of gluing aluminum is a perfect alternative to welding. Unlike the second option, the gluing process is relatively simple.
But you need to take into account the fact that only a special glue will bring successful results when working with aluminum. It should contain alkali and acids to enable splitting of an oxide film and improve the quality of bonding.
Today, there are many types of glue for bonding metals. The best among them are metal adhesives with a high level of viscosity. When choosing this material, it is also vital to pay attention to its safety – some products emit toxic substances during curing.

Overall, a good adhesive base for joining metal products must meet the following technical requirements:

  • maximum strength and reliability;
  • longevity;
  • resistance to maximum temperature changes;
  • water resistance;
  • no expansion and shrinkage during curing;
  • corrosion protection.

Types of aluminum glues

Most often, the following two adhesives are used for aluminum bonding:

Polyurethane glue. It the most common solution for aluminum. Polyurethane glue can be one- or two-component. For the latter, you will need to use a hardener. This type of glue is characterized by increased plasticity and heat resistance. When using one-component polyurethane glue, the surface is to be pre-treated with water. It will provide better adhesion and firm fixation of the surfaces. Advantages of polyurethane compounds:

  • Super strong bond;
  • Anti-corrosion effect;
  • High resistance to loads;
  • Fast curing;
  • Temperature-resistant.

Polyurethane adhesive can be used to bond aluminum to aluminum and other materials including steel, resin, stone, and glass.

Epoxy-based glues.

This agent had high adhesive properties and exclusive resistance to temperatures. Epoxy adhesives are used for the following purposes:

For the installation of aluminum structures, for strong joining of materials with different thermal expansion parameters;

These adhesives are suitable for bonding aluminum to wood, stone, glass. For high-quality adhesion of surfaces made of various materials, you may need an additional mechanical device like an elastic tape.

If you opt for a glue that is based on epoxy resins, you should remember that hardeners are added in different proportions, it is vital to follow the manufacturer’s instructions.

Instructions for gluing aluminum surfaces:

  • The areas you want to join must be free from rust and dirt. You can process the surface with a fine-grained using sandpaper).
  • The grease is easily removed with acetone.  If you fail to remove greasy stains, the adhesion result will be 20% weaker.
  • Then the surfaces must be properly dried.
  • If you use two-component adhesive, take a special container, which you will dispose of after use.
  • Follow the manufacturer’s instructions until you get a mixture smooth in color and viscosity. The ready-to-use glue must be used in the next 10-60 minutes. The specific time is usually indicated on the tube or package.
  • Apply glue to both surfaces in a very thin layer and press them firmly against each other. Do not overdo it to avoid squeezing out the adhesive mass.
  • Remove excess glue with a dry cloth. Sometimes you need a cloth soaked in a solvent.
  • Fix the position until the adhesive has completely hardened (about 15 minutes).
  • Depending on the brand of glue and the ambient temperature, final curing occurs in 12-24 hours.
