Aluminum that thick is very difficult to bend w o heating and even then it is likely to crack.
Bending 4mm aluminium sheet.
4mm thick is not sheet it is plate.
Place the fracture line over the edge of a table and bend the overhang slightly downwards.
Also known as press braking flanging die bending folding and edging this method is used to deform a material to an angular shape.
I doubt that you will get it hot enough to bend easily with a propane torch as you will need all the area you are bending at least cherry red and preferably hotter.
Bending sheet metal by hand is a manageable task if the piece of sheet metal is small and thin enough to handle.
If you are set on trying to bend it you could try bending it 90 deg.
Bending aluminium recommended press brake die set up for cold forming of sheet and plate.
With the aid of a straight edge and a sharp knife score both sides of the aluminium sheet.

Bending is one of the most common sheet metal fabrication operations.
Most frequently expensive sheet metal bending tools called brakes are used to bend sheet metal but you can also complete this task without one.
Sheet aluminium can be cut without the need for a guillotine or tin snips which tend to deform the metal.
Find somewhere with a hydraulic press and formers to do it for you and slip them a tenner.

How to bend sheet metal without a brake in 4 different methods with minimal or homemade tools.
The bend radius you select may not be available if the geometry of the part will not allow us to bend with the specific tooling required to achieve that radius.
Use the minimum bend dimension values in the charts below for your minimum closeness of cutout to a bend.
Maximum sheet thickness for all other steel is 6 mm.
This weakens the aluminium and creates a fracture line.
