If ambient temperature and anhydrous AlCl3 powder, then carbon steel is perfectly acceptable. If aqeous solution, then similar for HCl (Hastelloy B, non-metallic), which is what AlCl3 will form upon contact with H2O. High temperature anhydrous vapor, I have no idea.

Why does it have to be metal?

Many non-metal piping materials are very suitable and a lot more cost-effective than Hastelloys, high alloyed stainless steels, Titanium, etc.
