Consumerlab.com posted a blurb about aluminum exposure from various coffee brewing methods. Here is their summary:

There is a very long discussion thread on this site about Aluminum as a possible cause for AD. I'm not weighing in on that debate, but for those worried about their aluminum intake from coffee, this paper provides some data.
The full study citation is: Windisch, J., Keppler, B. K., & Jirsa, F. (2020). Aluminum in Coffee. ACS omega, 5(25), 15335-15343.A study evaluated how much aluminum is introduced into coffee brewed with an aluminum coffee pot or aluminum coffee capsules (such as Nespresso capsules), versus a steel pot, filter machine, or Turkish pot. It found that coffee grinds actually remove aluminum from the water used for brewing. However, aluminum coffee pots (but not aluminum capsules or other brewing methods) cause a net increase in aluminum in brewed coffee versus the water, although the amount of added aluminum in coffee brewed in aluminum pots was small and would contribute little to average aluminum intake per week (0.25 mg compared to average intake of 11.2 to 91 mg), but the researchers suggested that brewing methods without aluminum components should be preferred (Windisch, ACS Omega 2020).
