Tungsten Rod

A tungsten rod is a type of metal rod made from tungsten, which is a rare and dense metallic element. Tungsten has the highest melting point of all metals, which makes it ideal for use in high-temperature applications such as in welding electrodes and in the manufacture of heating elements for industrial furnaces.

Tungsten rods are typically solid cylindrical bars that come in various diameters and lengths, ranging from a few millimeters to several centimeters in diameter and several meters in length. They are manufactured through a process called sintering, which involves compressing tungsten powder into a mold and then sintering it at high temperatures and pressures.

Tungsten rods are known for their high strength, durability, and resistance to corrosion and wear. They are commonly used in a wide range of applications, including in the aerospace industry, the medical field, and the manufacturing of electrical contacts.

High Purity: Tungsten rods typically require a purity of at least 99.95%.

Diameter: Tungsten rods come in a range of diameters from 0.1 mm to 100 mm depending on the application.

Length: The length of the tungsten rod can vary from a few centimeters to several meters, depending on the application.

Straightness: The tungsten rod must be straight without any bends or warps.

Density: Tungsten rods must have a minimum density of 19.3 g/cm3.

Surface finish: Tungsten rods can be supplied with varying levels of surface finish ranging from as-drawn to highly polished.

Composition: The composition of a tungsten rod is typically at least 99.95% tungsten with trace amounts of other elements like nickel, copper, or iron.

Tolerance: The tolerance for tungsten rods is typically specified in terms of diameter tolerance, length tolerance, and straightness tolerance.
