Tungsten Alloy Extrusion Die

Tungsten alloy extrusion die is useful for processing both non-ferrous metals and alloy steels, the dies being made of a predominant amount of molybdenum or tungsten, the remainder being zirconium. It is usually used in the multiple extrusion process that is specially designed to prevent delaminating or cracking of the rods during extrusion.
Appliances for Tungsten Alloy Extrusion Die and Die Casting Components
Hard steel wire is generally made by forcing solid metal through a hole, called a die, under such intense pressure that it is extruded like pasta. Can you imagine the incredible forces that must be acting on the holes? In some cases diamond or sapphire (nearly as hard) dies are used. Chinatungsten offers excursion dies made of a tungsten alloy, because of its high strength at very high temperatures.

Because of its extraordinary prosperities of high heat resistance, good hardness, excellent plasticity ability, tungsten heavy alloy (WHA) is very suitable material for tolls such as extrusion dies, die casting components, etc., especially when it is employed in extrusion die of copper related alloy, the manufacture of aluminum, zinc and brass castings. It is made from a sintered material consisting of Mo and/or W containing 2-60% by volume of high melting point non-metallic components which are free from oxygen (except possibly in impurity amounts).
