Tungsten is thought to be formed from the explosions of massive stars
Instead, tungsten is thought to be formed from the explosions of massive stars. Each supernova explosion has so much energy that these newly created elements are jettisoned at incredible speeds of 30,000 km/s, or 10% of the speed of light – and that's how they get dispersed throughout the universe. Because of that, tungsten cannot be cast, forged, or rolled like other metals but must be pressed into shape while in powder form and then sintered. It is frequently alloyed with other metals, such as
