← HistoryWhich limiting outcome occurs when a brass astrolabe is manufactured with significant zinc content?
A)The instrument undergoes dezincification corrosion✓
B)Accuracy improves due to thermal gradient
C)Components become more resistant to oxidation
D)Engraving becomes more sharply defined
💡 Explanation
Dezincification corrosion occurs in brass with high zinc content because the zinc atoms selectively leach out in corrosive environments, leaving a weaker copper matrix behind; therefore, the structural integrity is compromised, rather than improved oxidation resistance or engraving.
