ASTM B777-15 class4 tungsten alloy block is usually acknowledged for their diverse features like as robust construction, reliability, and longer, service life. It provides a safer alternative to lead block, and their higher density also enables them to hold their shape better, even under extreme conditions. So it is widely used in military for making bullets, barrels, counterweights etc.
