Carbon Tubes are essential structural materials widely used in high-temperature, vacuum, and precision engineering applications. Manufactured from high-purity graphite or engineered carbon materials, carbon tubes provide excellent thermal stability, chemical inertness, and mechanical reliability, making them well suited for demanding industrial environments.
With a sublimation temperature above 3,600 °C (for graphite) and a typical density range of 1.8–2.2 g/cc, carbon tubes exhibit outstanding resistance to extreme heat, thermal shock, and rapid temperature cycling. Their stable crystalline structure and anisotropic properties allow precise machining and predictable performance under vacuum, inert gas, or reactive atmospheres.
Carbon tubes are widely used in applications including:
Semiconductor processing equipment and tubular fixtures
Vacuum systems and ultra-high-vacuum assemblies
Thermal management and heat-transfer components
Furnace tubes, liners, and protective sleeves
PVD / CVD tooling and gas-flow channels
Wear-resistant and chemically stable hollow structural parts
In advanced manufacturing, high-purity carbon tubes are valued for their low impurity levels, excellent electrical and thermal conductivity, and compatibility with high-temperature and vacuum processes. They are commonly used as heater tubes, shielding sleeves, support structures, and precision-machined components in semiconductor, optics, energy, and high-temperature industrial systems.
Overall, carbon tubes are indispensable materials for next-generation high-temperature and vacuum technologies, enabling reliable structural performance, thermal stability, and dimensional consistency across industries such as semiconductors, electronics, aerospace, energy storage, metallurgy, and precision manufacturing.
