One advantage of lasers is that they can cut sheets of steel half an inch (1.27 centimeters) thick, as well as sheets of aluminum one-third of an inch (0.9 centimeter) thick, with a high degree of accuracy. Yet lasers can only be used to cut very pure metals. And if the metal isn't pure or contains inconsistencies, either molten metal will splash onto the laser's lens or the cut metal will lack smooth edges. These restrictions make lasers less attractive for use by the automotive industry.
