← HistoryWhich outcome occurred when medieval instrument makers used brass alloys rather than iron when constructing astronomical astrolabes?
A)Corrosion resistance was significantly improved✓
B)Manufacturing complexity increased significantly
C)Thermal expansion was dramatically reduced
D)Accuracy of calibration became very difficult
💡 Explanation
Brass increases resistance to corrosion compared to iron using passivation. Therefore, the functional service life was extended, rather than encountering premature failure. Calibrating becomes more accessible because of a slower corrosion rate.
