With proper handling and preparation, epoxy can bond well to most aluminums and aluminum alloys. For additional information on compatible metals for epoxy bonding, see EPO-TEK Tech Tip 12. Aluminum presents a particular concern in bonding as it readily oxidizes to form an insulative/passivation layer of aluminum oxide.
How do you fix cast aluminum without welding?
Using a propane torch and some aluminum brazing rods is a quick way to bonding aluminum without using a welder. It makes for a very strong bond and with a little practice can be done quickly with great looking results.
