Two big issues when trying to glue metal to wood.
• Preparation. The aluminum should be "scratched" a bit (ScotchBrite) and wiped down with acetone. Light sanding on the wood and a tack cloth.

Best solution Hex self tapping stainless sheet metal screw w/sealing washer These will hold in plywood.
Shop for similar WITHOUT the rubber washer and you can buy those cheap.
