Which impurity introduced during the bronze smelting process alters mechanical behavior?

💡 Explanation

The use of arsenic as an alloying element affects bronze properties, because it causes intergranular weakness via grain boundary segregation, leading to embrittlement. Therefore the bronze becomes brittle, rather than possessing increased ductility or corrosion resistance.
