We track order production progress in real time. For after-sales problems, our team responds within 24 hours globally, and provides long-term technical training and product quality warranty.

Where are your carbon fiber products exported to? Do you have landmark engineering cases?

Our products are sold all over China and exported to Southeast Asia, the Middle East and Europe. We have cooperated with more than 2,000 clients worldwide. Our carbon fiber reinforcement materials have been applied to landmark projects including Guangzhou Pipa International Exhibition Center, Tianjin Olympic Sports Center and bridge & tunnel reinforcement projects.

Temperature Carbon-Carbon Bolts for Extreme Thermal and Corrosive Environments

2026-06-29 0 Leave me a message

JunTeng, a national high-tech enterprise specializing in high-performance fiber composites, has unveiled its Carbon-Carbon (C/C) Bolts – advanced fastening solutions engineered for structural integrity under extreme thermal, mechanical, and corrosive conditions.

Manufactured from carbon fiber-reinforced carbon matrix composite, these fasteners maintain exceptional mechanical strength at temperatures exceeding 1000°C, with capabilities extending above 2000°C in inert or vacuum environments. This represents a significant advancement over conventional metal bolts, which typically soften above 500°C.

Key Performance Advantages

High-Temperature Resistance: Maintains structural integrity and dimensional stability at extreme temperatures, preventing loosening or deformation caused by thermal stress.

Lightweight & High Strength: Delivers specific strength (strength-to-density ratio) exceeding five times that of steel, making it ideal for weight-critical aerospace and high-performance applications.

Corrosion & Radiation Resistance: Withstands acids, alkalis, and oxidation, with excellent radiation tolerance suitable for nuclear and high-energy physics environments.

Non-Magnetic & Contamination-Free: Contains no metal, eliminating galvanic corrosion risks and preventing metal contamination in semiconductor and photovoltaic manufacturing.

Diverse Application Fields

JunTeng’s C/C bolts are widely deployed across multiple high-end industrial sectors:

Semiconductor Manufacturing: CVD, diffusion, and sintering equipment requiring contamination-free fastening at 1300–1600°C

Photovoltaic Industry: Thermal field systems in single crystal furnaces

Aerospace: High-temperature structural components and fastening systems

Heat Treatment: Furnace fixtures and high-temperature thermal field components above 1000°C

With JunTeng’s ISO9001-2015, ISO14001-2015, and ISO45001-2018 certifications, the company delivers consistent quality across all C/C bolt products, available in custom dimensions and thread specifications.
