You could try the shop near the airport, LH side going north.

Couple of years back they manufactured a hand rail for the pool to my specs from stainless and the welds were excellent, so must have a competent welder.

From my previous life in aviation and working with "ally", only certain specs can be welded.
Dependent on the component (which you do not state) and the stresses put on it, will likely crack again, not from the original crack but from the Heat Affected Zone. As it is unlikely that they could heat treat or age harden the area of the weld.

There's a metal fab shop about 200 yards before the Big C (on the same side) on Pala U Road if you are heading inland. It's beside a big paint store.
They've done some stuff for us, but not aluminium. Worth a try.

Tend to agree with Chas.

On a side note, not many autos have aluminium parts, am curious as to what this part and its function is? I've worked in aviation as well as NDT, plus held a welding inspectors licence so will advise that if it's just a cosmetic non-stressed part you're probably okay to go ahead. If, however it is a load-bearing piece I'd source new from the manufacturer.

My two cents worth.

Sounds as if we have similar backgrounds.

I tell this story as component stress can come in many forms and may give OP food for thought.
Most car parts to be made of ally, are engine related.
Few years back I x-rayed a cylinder head as a "homer" (training exercise) and found a 1" crack from the spark plug hole seating (Honda I think). The engine water jacket included the spark plug holes and this it seemed was a common fault when over torqueing the plugs.
The component was much too thin to weld in that area and would have been subject to internal stress from the water jacket, likely to blow completely instead of the small seep and loss of coolant he had at that time, when the engine had reached working temperature.

Guy found a replacement at a local scrappy and I thoroughly inspected it before he fitted the head. Happy ending and a few beers down the road.
