Tungsten Copper Rod

Manufacturer of Tungsten Round Bar, ASTM B777 Flat Bar Dimension

Tungsten Copper Rod is made up of a mixture of tungsten and copper. There are different classes of these rods based on their chemical composition. Navstar Steel is a leading supplier of the Tungsten Copper Rod products. The minimum mixture has to have 50% of each element with the high alloys ranging up to 90% copper in material. The material has good electric conductivity and thermal conductivity.

Most of the Tungsten Round Bar products are made with a diameter range of 0.75mm to 127mm, length range of 3.81mm to 1000mm and under the standard ASTM B702. There are also different types such as the WCu10, WCu20 and above. The ASTM B777 Flat Bar is used in the automotive industries, aerospace industries and in nuclear industrial applications. It is the high thermal conductivity and the high electric conductivity of this material that launches it into these specific industrial applications.


The Copper Tungsten R07004 Hollow Bar is used to reduce the weight of the product in relation to the length and diameter. There are different types and forms to the tungsten copper rods such as the Tungsten Square Bar. The material is sometimes used for its primary purpose where are secondary need for strength arises. In cases like this, the material has to be in a geometrical shape that allows them to be strong. For this reason the square bar and the Tungsten Alloy Hex Bar are used. Please contact us for more information on the tungsten copper rod and its pricing.
