The lightweight, low expansion, and high strength characteristics of carbon fiber have a positive effect on vibration, deformation, and energy consumption, especially in very dynamic environments. The most significant effect is the vibration damping characteristics. By reducing unwanted vibrations during the grinding process, the lifespan of the grinding wheel is greatly extended, and the quality of the workpiece (such as chatter marks and roundness) is dramatically improved.

"SGL's C/C composite (SIGRABOND) is..." Stronger than conventional graphite materials and traditional C/C materials. It has the highest level of bending strength, tensile strength, and bending rigidity among C/C materials. Therefore, it allows for further weight reduction of furnace materials and heat treatment jigs. In particular, it is ideal for applications as a metal alternative and for weight reduction, as it does not suffer from damage due to impact. It can be used for applications exceeding 2500°C as components for high-temperature furnaces. Various coatings and impregnations are possible. It also excels in thermal shock resistance. "If you use SIGRABOND C/C..." You can achieve thinning without changing the outer dimensions. The German design team will develop and design according to your requests. "SGL Carbon is the only manufacturer that..." Covers all C/C manufacturing processes from fibers to finished parts. "For oil quenching, use SIGRASIC C/SiC!" SIGRASIC C/SiC, produced by impregnating C/C with molten silicon, is a material with a dense structure. It has a low porosity rate, and there are no issues such as furnace contamination during oil quenching.

SiC Gradient Coating is a "boundary-less" SiC coating that can be obtained by treating the surface of graphite through a chemical conversion process. The bond between the graphite substrate and the SiC coating is strong. The surface exhibits the excellent properties of SiC while preventing the SiC coating from being affected by thermal and mechanical loads. Applications include... ⇒ Preventing oxidation of conventional graphite materials ⇒ Improving wear resistance of conventional graphite materials ⇒ Reducing the weight of SiC components *It is also possible to perform polishing after the coating formation.

Extruded graphite has a larger particle size than isotropic graphite. Therefore, it is inferior in terms of strength, but it also has the advantage of high thermal and electrical conductivity. In addition to its properties, extruded graphite is also easier to process and is more cost-effective. Furthermore, vibration-molded graphite is more isotropic than extruded graphite and can accommodate larger sizes. <Main Features> ◎ High-temperature stability ◎ Chemical resistance ◎ Thermal shock resistance ◎ High conductivity (thermal & electrical) ◎ Machinability ◎ Suitable for large products (especially vibration-molded graphite)
