Thanks for your ruling Imp. Also, just pointing out that the Leviathans have metal armor that even Hulk couldn't destroy with a full force punch that caused one to buckle and flip over. While Hulk quite casually rampaged and smashed through every wall in the Hellicarrier. One was made from alien metals, and the other from Earth metals. Hmmmm.
1. Hulk rip the armor like it was tissue paper. What are you talking about?
The armor was destroyed by lightning, Tony blew the armor into pieces with a missile, etc.
2. Spaceships are not necessarily made of the same material. Fighting space ships have been destroyed by conventional weaponry many times in fiction. Some ships are designed to shield from cosmic radiation.
3. Thanos ship is not necessarily his own tech but can be the tech of some other species that built the ship for him or gave him the ship or it was the ship Thanos took by force. The tech behind the leviathan (both leviathan and chitauri are a different species than Thanos) could also not be of Thanos design. He could have just recruited them or force them to join him.
These are just a few reasons, there are more reasons why it is not necessary of the conclusion you are implying.
