SGL Group Presents Comprehensive Range of Specialty Graphite for Casting Applications and High-Temperature Furnaces

At its booth SGL Group will exhibit the most comprehensive range of specialty graphite industry-wide. Based on this broad material base experts identify the best solution for the special requirements of each customer. Specialty graphite products of SGL Group are typically used in applications like continuous casting of non-ferrous metals or the heat treatment of steel components for the automotive industry.

SGL Group’s service portfolio includes:

• Casting dies made from SIGRAFINE® fine-grain graphite for continuous casting
• Degassing tubes made from SIGRAFINE® NOX treated for aluminum production
• Engineering for heating chambers and charging fixtures for high temperature furnaces
• Charging fixtures made of SIGRABOND® carbon fiber-reinforced carbon (C/C)
• Carbon and graphite products for heating chambers of high temperature furnaces, e.g. heating elements made of SIGRAFINE® fine-grain graphite or SIGRABOND® C/C and thermal insulations made of SIGRATHERM® rigid and soft carbon and graphite felt

Burkhard Straube, Chairman of the Business Unit Graphite Materials & Systems: “Our strength is the combination of material and application know-how for casting and high temperature applications based on our comprehensive specialty graphite portfolio. Therewith we develop customized, efficient solutions for the production processes of our customers.”

For instance, the C/C material SIGRABOND® Performance offers clear advantages versus traditional carbon fiber-reinforced carbon with an up to 20 percent higher rigidity and a lower porosity. It also serves as material base for the design and manufacture of charging fixtures for the optimized loading of heat treatment furnaces, like pusher-through hardening furnaces with gas or oil quenching, and of charging plates for vacuum sintering furnaces for the production of cemented carbides.


SGL Group is one of the world’s leading manufacturers of carbon-based products and materials. It has a comprehensive portfolio ranging from carbon and graphite products to carbon fibers and composites. SGL Group’s core competencies are its expertise in high-temperature technology as well as its applications and engineering know-how gained over many years. These competencies enable the Company to make full use of its broad material base. SGL Group’s carbon-based materials combine several unique properties such as very good electrical and thermal conductivity, heat and corrosion resistance as well as high mechanical strength combined with low weight. Due to industrialization in the growth regions of Asia and Latin America and increased substitution of traditional with innovative materials, there is a growing demand for SGL Group’s high-performance materials and products. Products from SGL Group are used predominantly in the steel, aluminum, automotive and chemical industries as well as in the semiconductor, solar and LED sectors and in lithium-ion batteries. Carbon-based materials and products are also being used increasingly in the wind power, aerospace and defense industries.
