Which risk increased when alloying tin into copper to produce bronze?

💡 Explanation

When tin is added to copper creating bronze, intergranular corrosion can occur under cyclic stress because tin segregates at the grain boundaries, increasing susceptibility to crack propagation due to local electrochemical potential differences. Therefore cracking risk increases rather than oxidation, thermal conductivity or radiation sensitivity, which require distinct material properties or mechanisms.
