Yes, however.
Strategic resources in ships can be converted into alloys/minerals equivalent, how many extra ships do you need to perform the same task without using them compared to with, compared to the production cost, the gist of which is that it's more mineral efficient to have ships with then without, but the margin is small. Because of that small margin if your still alloy bottlenecked for the quantity of ships your using and losing then you want to hold at the strategic resourceless components, sort out your alloy production, and only then start upgrading your ships to higher tier components.
Beyond that things get complex, as it's a bit tricky to weigh the advantage of having a few battleships do 2% more damage over an extra three artisans.
