BZN Carbon manufactures and supplies premium-quality carbon composite fasteners, including bolts, nuts, screws, and studs. Our carbon fiber reinforced carbon (C/C) fasteners are engineered using advanced composite structures such as 2.5D, 3D, and 4D — with bulk densities ranging from 1.7 to 1.9 g/cm³, depending on the application and customer requirements.

What Are Carbon Composite Bolts and Nuts?
These fasteners are made from carbon-carbon composite materials, which combine carbon fiber as the reinforcement phase with a carbon matrix. This combination offers outstanding thermal, mechanical, and chemical resistance properties that surpass traditional metallic fasteners in high-temperature and corrosive environments.

Applications
Carbon composite bolts and nuts are widely used in:

Aerospace and aviation assemblies
High-temperature furnaces and vacuum chambers
Semiconductor and solar industries
Lightweight structural components in motorsports and defense
Cryogenic and thermal barrier systems

Advantages of C/C Fasteners:

Exceptional strength-to-weight ratio
High temperature resistance (up to 2000°C in inert/vacuum conditions)
Outstanding corrosion and thermal shock resistance
Electrically conductive and low thermal expansion
Non-magnetic and chemically stable under extreme conditions
