Lightweight design is possible with SGL's high-strength and high-rigidity C/C composites! There are also C/SiC composites that can be used for gas carburizing and oil quenching!
"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.
