 Copper - graphite alloys are lighter and lower in cost compared to leaded copper alloys, in addition to being nontoxic.These are ultra light materials that are designed to protect people from the impact of weapons, vehicles or explosions, by the absorption of the energy generated during these impacts.Crumple zone, frame members and reinforcements, helmets, military vehicles, blast resistant structures, wind turbine blades, and pedestrian impact zones are examples of the application of these technologies.
