Graphite plays a key role in the mobility of tomorrow. Whether in brake pads, seals, batteries, or as a lubricant – our graphite solutions ensure efficiency, safety, and longevity in vehicle components. With customized products, we support the development of modern drive technologies and sustainable mobility concepts.
Graphite is a key material in batteries and accumulators because it offers high conductivity and stability. Its structure enables the efficient storage of lithium ions and makes it indispensable for modern energy storage systems.
Carbon brushes ensure current transmission in electric motors and utilize graphite for good conductivity, lubrication, and wear resistance. High-quality vein or natural graphite ensures long-lasting performance even under high loads.
Graphite is used in forging as a lubricant and release agent, reducing friction and protecting tools. Water- or oil-based graphite lubricants ensure precise results even under high temperature loads.
Powder metallurgy components are indispensable in modern manufacturing, especially in the automotive industry. For self-lubricating sintered parts, graphite is added to metal powders to lubricate the mixture during the pressing process and minimize tool wear. During the subsequent sintering process, fine graphite diffuses into the metal surface layer, increasing mechanical strength and improving the sliding properties of the finished workpiece. This results in a high-precision, durable component with optimal properties for demanding applications.
Graphite is an important component of friction linings, ensuring consistent braking performance, low noise, and good heat dissipation. It also forms a protective film and contributes to optimal performance and safety.
Expanded graphite is the basis for flexible, temperature-resistant seals that reliably seal even under extreme conditions. They offer high safety and are used in numerous industries.
Graphite acts as a high-performance lubricant even under extreme conditions, reliably reducing friction. Thanks to its structure, it functions cleanly and efficiently, even where oils fail.
Graphite is indispensable in the chemical industry: as a material for reactors, heat exchangers, seals, and electrodes. Our high-quality graphite products withstand extreme temperatures and aggressive media, enabling reliable processes in demanding production environments.
In addition to standard dispersions, GK Graphite also develops customized solutions for special applications. Thanks to the versatile properties of graphite, these solutions open up new possibilities in high-tech and industrial processes.
In addition to our own graphite dispersions, we also offer our customers contract manufacturing services. We utilize our specialized equipment and expertise to produce their products with consistent quality and reproducible properties.
Graphite is used as an additive in plastics to specifically improve mechanical stability and heat dissipation. This enables the creation of high-performance composite materials for demanding technical applications.
Graphite has a long history – and remains indispensable in classic applications. Whether in pencil leads, molds, lubricants, or as a component of refractory materials: Our products combine proven quality with modern manufacturing, thus ensuring the performance of traditional applications.
The pencil is based on the discovery of graphite and is still used today for writing and drawing. Different mixtures with clay create varying degrees of hardness for precise applications.
In the sintering of hard metals, graphite acts as a release agent and lubricant, preventing components from sticking and ensuring they remain protected. This results in precise, dense, and high-quality surfaces.
Graphite is used in iron and steel processing to selectively increase the carbon content and improve material quality. This results in high-quality foundry products with high strength and reliability.
Graphite offers reliable protection when it matters most. In textile coatings, it provides heat resistance and antistatic properties, while in fire protection, as a component of flame-retardant materials, it safeguards lives and infrastructure. Our products make a significant contribution to safety in industry, construction, and everyday life – robust, proven, and innovative.
Expanded graphite acts as a flame retardant by forming an insulating protective layer when exposed to heat, inhibiting flames and gases. It has a wide range of applications and increases the safety of buildings and facilities.
Graphite gives technical textiles heat resistance, antistatic properties and high stability for demanding applications. It thus enables reliable performance as well as solutions for protection, shielding and special functionalizations.
Graphite plays an important role in metal processing as a lubricant, release agent, and additive, thus improving process stability and material properties.
It contributes to the reduction of friction and wear, enabling the production of high-quality, precise components.
Graphite is used as a carburizing agent to increase the carbon content of molten metals. This allows for the targeted adjustment of material properties such as hardness and strength. High-quality graphite is characterized by a high carbon content, low impurities, and good solubility in the melt.
Graphite-based casting and mold coatings are used to improve the surface of casting molds and facilitate demolding. The graphite they contain is temperature-resistant and possesses good lubricating and release properties, thus reducing metal adhesion.
Graphite dispersions are indispensable in forging because they provide lubrication and release properties, thus improving quality. They optimize the process and increase important parameters such as output and tool life.
Graphite is crucial in the production of seamless tubes: as a coating on the mandrel, it ensures optimal lubrication, reduces friction, and protects tools. AMG Graphite's heat- and pressure-resistant graphite dispersions are a reliable, environmentally friendly, and field-proven solution for tube production.
In the construction industry, graphite is valued for its outstanding thermal and electrical properties. Our products are used in insulation materials, fire protection systems, and specialty coatings. They contribute to making buildings safer, more energy-efficient, and more durable – from planning to completion.
Graphite improves EPS insulation materials by significantly increasing thermal insulation through the reflection of infrared radiation. This results in efficient, space-saving solutions for modern, energy-optimized buildings.
Expandable graphite supports preventative fire protection: When heated, it expands, forming an insulating protective layer and slowing the spread of flames. In upholstered furniture, car seats, carpets, or pipe collars, it seals cavities and protects against combustion gases.
Graphite gives paints and varnishes a sophisticated appearance and reliable corrosion protection. It protects surfaces from environmental influences, for example in shipbuilding, and thanks to its oxidation resistance, temperature stability and environmental friendliness, it is ideally suited for high-quality coatings.
