Metallurgists at the University of Pittsburgh have developed a lead-free steel that should allow car makers to prepare for new legislation in the US that will ban lead in mass-produced products. The tin-based steel is designed to replace the 3 million tonnes of a steel formulation called 12L14 used every year worldwide to make fuel injectors, transmission parts and many other car components. Isaac Garcia at the university says that despite the lack of soft lead, the new alloy replicates 12L14’s high machinability. The research, supported by an international consortium of steel companies,
