Which risk increases when tin content falls below optimal range in early bronze metallurgy casting?

💡 Explanation

When tint content drops insufficient bronze occurs because it weakens solid solution hardening, leading to greater weakness therefore propensity for ductile fracture is elevated, rather than precipitation hardening, lessened work hardening effect or significant oxidation which would occur at higher temps with other alloy deficiencies.
