GRAPHITE BLOCKS
Graphite blocks, made from high-purity carbon, combine excellent thermal stability, electrical conductivity, and resistance to chemical corrosion and wear. They withstand extreme temperatures and harsh environments, making them essential in industries like metallurgy, electronics, and chemical processing. Available in types such as isostatic (for high precision), molded (cost-effective and machinable), vibrated (economical for medium-density uses), and extruded (general purpose), graphite blocks offer versatile solutions tailored to diverse industrial needs.

PRODUCT VARIANTS
ISOSTATIC GRAPHITE BLOCKS
We provide a wide range of high-density isostatic graphite, tailored for industries such as continuous casting dies for brass, copper, and aluminum, electric discharge machining (EDM), and vacuum evaporation of metals like aluminum, gold, and silver. Our graphite is also ideal for semiconductor applications, including crucibles, sealing rods, jigs, boats, as well as dies and molds. We offer customizable packaging options to meet your specific requirements.
