Tungsten rhenium rod has high melting point, low vapor pressure, good shock resistance, and excellent strength, toughness and oxidation resistance at high temperature. Tungsten-rhenium rods are mainly used in the aerospace field and other high-temperature field components, friction stir welding joints, etc.

From the perspective of physical and chemical properties, Tungsten rhenium Rod combines the characteristics of tungsten and binders, such as high melting point, high density, high hardness, high strength, low thermal expansion coefficient, high elastic modulus, wear resistance, high temperature resistance, good electrical conductivity thermal conductivity etc. Note: The specific physical and chemical properties of the alloy are also related to the ratio of raw materials. When the binder is metallic copper, the color of the alloy will be more copper-colored with the increase of copper content; with the increase of copper content, the melting point, density and hardness of the alloy will change. Will be reduced, while the electrical and thermal conductivity will be better.
From the perspective of production technology, the production methods of Tungsten rhenium Rod with different chemical compositions are different. For example, tungsten-nickel-iron alloy rods can be produced by powder metallurgy technology or injection molding technology. Powder metallurgy technology refers to the process technology of various types of products manufactured by using metal powder as raw material after forming and sintering; injection molding refers to a certain The shape of the model is a technology that injects the colloid in the molten state into the mold cavity by pressure to produce the desired product. The tungsten-copper alloy rod is usually manufactured by the copper infiltration method, that is, the tungsten powder is first pressed into shape, and sintered into a tungsten skeleton with a certain porosity, and then a series of operations such as infiltration of copper elements are sufficient.
When Tungsten rhenium Rod is processed into wire, it can be used as filament, support wire and lead-in wire; it can also be ground into needles, manufactured into various electrodes, high-speed cutters and sputtering targets, etc.
