Tungsten Alloy Extrusion Die

What is extrusion die and die casting components?

This invention relates to extrusion dies 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 zirconia. Extrusion die is usually used in the multiple extrusion process which is specially designed to prevent delamination or cracking of the rods during extrusion.

Die casting components products are usually used in die casting tooling, particularly in the manufacture of aluminum, zinc and brass castings, to ensure the long die life and minimum shrinkage porosity of the components.

Appliances for tungsten alloy extrusion dies 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, but this one is made of a tungsten alloy, probably because of its high strength even at very high temperatures.

On account of its prosperities of high heat resistance, good hardness, excellent plasticity ability, tungsten heavy alloy (WHA) is quite 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. Extrusion dies are 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).

There is another property for tungsten heavy alloy is durable, which guarantees its longer life than traditional die materials, and assure the minimum shrinkage porosity of die casting components. So the extrusion dies made of such raw material as tungsten are available with an assurance of high quality and standard.

Major advantages of tungsten alloy extrusion die and die casting components
High thermal stability
High impact resistance
Good machinability
Excellent crack resistance
Reduction in press down-time
Minimal extruded metal pick-up
