Bonding Aluminum To Aluminum Epoxy

Aluminum is a relatively soft durable lightweight ductile and malleable metal that is easily machined cast drawn and extruded.

Bonding aluminum to aluminum epoxy. Single component epoxies are ideal for bonding aluminum. So the strength isn t the same but it s more than the industry average. Anodized aluminum is an electrolytically induced passivation process where several physical changes occur to the surface including. It is nearly always alloyed to improve its mechanical properties.

It has a tensile strength of 2424 psi and heat resistance of 300 degrees fahrenheit. Ms polymers form weather resistant bonds to aluminum and have very low shrinkage rates. So it kept the reputation. Epoxy adhesive is available in one or two component versions.

All grades will bond aluminum well. They are good for bonding large areas providing a moisture seal and can even be painted over. For very high strength use a metal bonder such as 170 or the original 910. Consider es550 or es558.

As we said earlier this one s just a quick setting version of the strongest bond creating metal epoxy. Although aluminum is a common bonding substrate for epoxy anodized aluminum can present its own set of bonding problems. To glue aluminum you have the choice of three different types of adhesive. For bonding aluminum to dissimilar surfaces with different coefficients of thermal expansion consider toughened 737.

Aluminum resists corrosion because a thin layer of aluminum oxide forms almost immediately when the bare metal is exposed to air. They are popular in the construction industry. Like slow and medium metal bonding adhesives fast metal bonding adhesive also guarantee corrosion protection replaces welding and has the fastest de clamp. Bonding with this adhesive is extremely resilient and durable.

Thicker aluminum oxide layer increased porosity and increased strength brittleness. In order to bond aluminum you ideally need a construction adhesive.
