How to Glue Aluminum How to Glue Aluminum
Aluminum can be glued to another piece of metal or other material with a glue that will keep it secure. An epoxy glue for metals or watertight epoxy bonds nonporous surfaces such as aluminum to other surfaces. Epoxy glue contains fumes. Use it outside.
Preparing the Aluminum for Gluing
Wash the side of the aluminum which is to be bonded thoroughly with a mild soap and water to remove dirt and oil. Rinse the residue. Dry the pieces of aluminum with a rag. Sand the area that is to be glued. The sanded area will help the glue adhere better to the metal. Rinse away the dust and dry the aluminum.
Gluing the Aluminum
Squeeze several drops of epoxy from the tube onto the sanded aluminum. Set the aluminum against the second surface and hold it in place with masking tape or a workbench clamp. Place a thin block of wood against the aluminum in the clamp to keep it in place as the glue dries. The label on the epoxy will tell you how long it takes for the glue to dry. Once the glue is dry, you can remove the tape or clamp from the aluminum.
