Headlight reflector in my eg housing is broken.

Can I replace this, I couldnt find anything on it, if not can i fix it with jb weld, or apoxy? If so which one. Ive had bad luck in the past with quick setting apoxy. Or use soldering iron? Im not sure what the part is made of, i think aluminum.
The part came from a black housing made for eg's
