Broken Tungsten. Would be EXTREMLY DENSE, and when dropped too far, can create a Hi Pressure area, making a crater
You get it by breaking tungsten.
Also would conduct Electricity better than brmt

Well, It has some differences with BRMT but isn't useful since we have DMG for making craters and high pressure. Also we have some high speed conductors, ej. Gold. So (IMO) it would not be something useful
