Try Q-bond. I’ve used it before to good effect, but it might depend on the metal/alloy in question

Q bond is good , but is based on superglue, no good over time if it gets wet or damp.

My go to would be silicon adhesive, the hard stuff that bonds car windscreens in, waterproof and rock solid but has some flex.
If you have to buy a whole tube though ,youre half way to the new part, unless you know someone who uses it.

That’s good to know! Thanks.

Perhaps a metal epoxy putty may be easier to use than a glue. Lots of manufacturers to pick from.

^ That. 

Degrease the surfaces to be bonded with thinners, allow the thinners to evaporate and then scrub the surfaces with a course abrasive, knock off the dust and bond, leave to set, then fit. Job done.

If you are just going to use an adhesive along the lines of the breakage then it will be weaker than it was before and the repair will likely not last long. If you can build up the area around the breakage; space permitting, you stand a greater chance of creating a lasting fix.

Can't you use a self tapping screw or a pop rivet 

The part that's broke is a piece of the bracket where the screw from the hinge connects to.

Hi Steve

Chemical Metal is good - friend used it on a car engine with no problems.

I used it to bond a plate over an exhaust box hole - it didnt fail - the adjacent metal rusted!

A picture of the broken component would be useful.  

If appearances don't matter, try this method:  (1) Reinforce with metal strips.   (2) Cover with thick layer of epoxy adhesive.   (3) Bind tightly with fine copper wire so that it digs into the epoxy.
