I have used this glue (2015) many times with mixed success for bonding aluminium to aluminium. I have to admit I gave up on it in the end as I could not get consistent results. Some joints are still going strong after two years, some identical joints failed within days under light loads.
I believe the key phrase in the document you posted is "apply to a pre-treated and dry surface". What pre-treatment is necessary to get a high strength reliable joint? I thought that I was careful in my pre-treatment. I would anodise, lightly abrade then and then degrease with acetone.
The problem as I see it with these glues is consistency especially in the environments used by a home builder.
The following document lists the surface preparation and pre-treatment recommended by araldite.
