I have used 2117 aluminum shafts with my recurves in those similar draw weight ranges and then shoot fine.
I would think 2018s would be a little weak potentially depending on point weight.
I have also used .400 spine carbons (Carbon Express piledriver 250-they have their own number system but this is a .400 spine) . The .400s I experimented by adding brass inserts and settled on 50 grain brass with 150 broad heads. With 4" feathers and a wrap total arrow weight is around 550 grains or so. Carbons are much quieter than aluminum in the woods and on the bow if incidental contact is made with shelf etc.
Long way of saying that 2117s should be fine and if you want to develop carbons .400’s would be a good place to start.
