Tungsten heavy alloys

Die casting is a manufacturing process that demands materials with exceptional resistance to extreme conditions, including elevated temperatures and pressures. These materials must also exhibit dimensional stability and wear resistance, ensuring their durability in the face of the process's demands. Among the many materials available, tungsten heavy alloys are increasingly gaining attention. Tungsten heavy alloys are composites made primarily of tungsten (usually 90% or more) with small amounts of nickel, iron, or copper to enhance ductility and strength. Tungsten itself is renowned for its extremely high melting point (around 3422°C), excellent hardness, and remarkable density. By alloying tungsten with other metals, the resulting materials retain tungsten's core advantages while improving workability. These properties make tungsten alloys ideal candidates for applications demanding high mechanical performance under challenging conditions, such as aerospace components, radiation shielding, and military equipment. Given their robust characteristics, it’s reasonable to consider whether they could also serve a role in die casting.
