Lead-free motors

Published: Wednesday 15 September 1999

Metallurgists at the University of Pittsburgh have developed lead-free steel that will allow carmakers to prepare for a new legislation in the US that will ban lead in mass-produced products. The tin-based steel will replace three million tonnes of a steel used every year worldwide to make fuel injectors, transmission parts and many other car components.
