Tungsten Properties
With melting point over 3000 degrees centigrade, tungsten is well known as a high performance material. Also it has low vapor pressure at elevated temperatures and low coefficient of thermal expansion. Tungsten material is widely in high temperature furnace components, lamp filament, electronic industry and other high temperature usages.
Pure Tungsten Rod / Tungsten Bar Production
Tungsten Rod / Tungsten Bar is produced with random lengths or customers' desired lengths by powder metallurgy method. Diameters can be made as per customers' requests. Tolerances can be made on request. Usually there are three different surface processes or finishes for customers' choice, depending on the different usages demand.
Pure Tungsten rod / Tungsten Bar Surface Finish
● Black - Surface is "as swaged" or "as drawn"; retaining a coating of processing lubricants and oxides.
● Cleaned - Surface is chemically cleaned to remove all lubricants and oxides.
● Ground - Surface is centerless ground to remove all coating and to achieve precise diameter control.
Pure Tungsten rod / Tungsten Bar Usages
1. High-Temperature Environments: Due to its excellent high-temperature resistance, tungsten rods are widely used in high-temperature environments. For example, in the aerospace field, tungsten rods are often used to manufacture parts for high-temperature engines and spacecraft to withstand extreme thermal and pressure conditions.
2. Homogenization and Stirring: Due to its high density and hardness, tungsten rods are often used for homogenizing and stirring materials. In the chemical industry, tungsten rods are used to prepare high-precision mixing equipment to ensure that materials are thoroughly mixed and maintain homogeneity.
3. Electrodes: Tungsten rods are one of the ideal materials for making electrodes. Tungsten electrodes used in aluminum welding are a common application. Due to tungsten's high melting point and low coefficient of thermal expansion, tungsten electrodes perform excellently at high temperatures and high currents, and have a long service life.
4. X-ray and Radiation Protection: Due to its high density and high absorption capacity, tungsten rods are widely used in X-ray and radiation protection. In medical imaging, tungsten rods are used as shielding materials to protect medical staff and patients from radiation damage.
For wear and cutting, the high hardness of tungsten rods makes them ideal for manufacturing cutting and abrasion tools. For example, in metal processing, tungsten rods are often used to process hard metals such as stainless steel and titanium.
As a special material, tungsten rods have wide applications in high-temperature environments, homogenization, electrode preparation, radiation protection, and cutting tool manufacturing. Their unique physical properties, such as high melting point, high density, and high hardness, give tungsten rods excellent performance in these fields. With the continuous advancement of science and technology, the application areas of tungsten rods will continue to expand, bringing greater convenience and benefits to various industries.
