Any threads I use copper anti seize it's just the best practice.

Galvanic corrosion is an electrochemical process in which one metal corrodes preferentially to another when both metals are in electrical contact, in the presence of an electrolyte.
Dissimilar metals and alloys have different electrode potentials,

compatibility of two different metals may be predicted by consideration of their anodic index. For environments, such as outdoors, high humidity, and salt environments, there should be not more than 0.15 between the metals.
ANODIC INDEX
AKA Reactive
Gold, solid and plated, Gold-platinum alloy 0%
titanium Nickel, solid or plated, 0.30
Copper, brasses or bronzes nickel-chromium alloys 0.35+-
Chrome moly .85

So do the math don't mix and match
