Seamless Tungsten Tube

Product Introduction

The Seamless Tungsten Tube from Shaanxi Chuanghui Daye Metal Material Co., Ltd. is a premium product designed for high-temperature, high-stress, and chemically aggressive environments. Made from ultra-pure tungsten and tungsten alloys, this tube offers excellent thermal stability, outstanding mechanical strength, and superior resistance to corrosion and oxidation.

Manufactured under stringent quality standards such as ASTM, AMS, ISO, and GB, the Seamless Tungsten Tube is suitable for both industrial and research applications. Its seamless design ensures uniform wall thickness, eliminating weak points and providing enhanced structural integrity for demanding applications. With precise tolerances and a smooth internal surface, this tube is ideal for vacuum systems, high-temperature furnaces, and metallurgical processes.

Size 

Material : pure tungsten 99.95%

Density: 19.3g/cm3

Specification: ODφ6-φ150mm*Wall thickness 0.3-25mm*L 30-1000mm

Property

High melting point and deformation resistance: The melting point of tungsten tube is as high as 3420 ℃, which makes it perform well in extreme high temperature environments. In addition, tungsten tubes have minimal deformation after multiple uses and exhibit excellent creep resistance.

High density and hardness: Tungsten has a high density, which allows tungsten tubes to maintain high strength and hardness at high temperatures. This characteristic makes tungsten tubes perform well in high-temperature environments and suitable for applications that require high strength and hardness.

Good thermal conductivity: The high thermal conductivity of tungsten makes it excellent in heat exchange and conduction. This makes tungsten tubes very effective in applications such as high-temperature furnaces and thermocouple protection tubes.
