Bonding Aluminum Sheets Together

Take care to encircle bolt holes properly.

Bonding aluminum sheets together.

Riveting is a very useful sheet metal joining technique. Apply the adhesive to the areas that you wish to be bonded. Single component epoxy aluminum adhesives cure with heat to form high strength structural bonds. Different brands of epoxy mature at varying rates but most require 24 hours curing time.

It just feels right that bonding metal with a metal fastener is a good choice but. Press the metal pieces together firmly and use adjustable clamps to hold them in place. Adhesive bonding metal fasteners are almost as old as metalworking and people are familiar with them. Rivets are used to form solid strong and permanent bonds.

Adhesive bonding joining with mechanical fasteners vs. Ms polymers form weather resistant bonds to aluminum and have very low shrinkage rates. They are popular in the construction industry. Cyanoacrylate also known as instant adhesives super glue crazy glue ca glue etc.

They are good for bonding large areas providing a moisture seal and can even be painted over. We know about metal too but what we really know is how to bond metal. In some cases though these methods may not be practical and you may need to look for quicker easier methods of gluing aluminum to itself or other materials. Aluminum isn t impossible to bond but you must work carefully and slowly especially if you have a lot of joints to seal.

Riveting is the process of joining metal pieces together by using mechanical fasteners. If so cyberbond has aluminum adhesives you can count on. For very high strength use a metal bonder such as 170 or the original 910. Like slow and medium metal bonding adhesives fast metal bonding adhesive also guarantee corrosion protection replaces welding and has the fastest de clamp time of the three.

Go to a automotive paint and body supplier and check out the epoxys this stuff is so strong that they took two pieses of sheet metal like 16ga and bonded it w a 1 4 overlap and about 30 45 sec later w a 10 ton porta power w mo clamps hooked to each tried to pull apart and they ended up riping one of the sheets about an inch from where bonded this stuff is taking the place of welding panels back in body shops all over. Permabond offers several grades which are colour matched to aluminium to appear like welding or brazing. For gasketing flange sealing lh197 is a particularly good choice for softer aluminum alloys. All grades will bond aluminum well.

Due to aluminum s chemical properties adhesives will obtain 100 of their strength when bonded to aluminum. Adhesive technologies such as acrylics epoxies and cyanoacrylates bond with this lightweight versatile and corrosion resistant metal.
