1. J-B Weld 8281 Reinforced Epoxy- Best JB Weld for Aluminum.
Cracked aluminum can be adequately repaired without welding using an epoxy embedded with aluminum. The aluminum particles contained in the epoxy will adhere to the cracked part, creating a permanent bond that will hold up in most situations.
Beside this, Can you fix broken cast aluminum?
You don’t have to be a professional TIG welder to repair aluminum professionally. You can actually use Aluminum braze to repair cracks, holes, leaks, rivets, broken ears, threads or fabricate aluminum, cast aluminum, and cast iron quickly, easily, and stronger than new. … Many aluminum alloys can be brazed.
Likewise, Is it possible to weld cast aluminum?
A: The short answer is that, yes, most aluminum castings are readily weldable. … These are not heat-treatable but are readily weldable using 5356 filler. However, the family of 7XX. 0 aluminum-zinc (AlZn) casting alloys, also heat-treatable, are considerably more difficult to weld.

Will JB Weld work on cast aluminum?
I am a professional tig welder and used to work at a local job shop one thing that I always hate is when someone brings in a case or any other aluminum component that they have tried to fix themselves, cast aluminum is very porous and the jb weld will get into the pores and it is almost impossible to weld.
