Which consequence results when medieval astrolabes used subpar metals?

💡 Explanation

Distorted plate alignment on an astrolabe degrades the tool's function. A difference in metals results in differential thermal expansion, because each expands differently with heat increase causing plate misalignment, therefore optical calculations become unreliable as the planes become non-parallel and rotational symmetry is thrown off, rather than affecting optical elements directly.
