Frequently Asked Questions (FAQ)
What are graphite blocks used for?
Graphite blocks are used as raw material or functional components in high-temperature furnaces, metallurgy, semiconductor equipment, EDM electrodes, and chemical processing systems.
What is the difference between isostatic and molded graphite blocks?
Isostatic graphite has uniform properties in all directions and finer grain size, making it suitable for precision applications. Molded graphite is more economical and commonly used for general industrial purposes.
Can graphite blocks be machined into custom parts?
Yes. Graphite blocks are commonly machined into plates, rods, fixtures, molds, and other custom graphite components based on drawings.
Are graphite blocks suitable for vacuum furnaces?
Yes. High-purity graphite blocks perform very well in vacuum and inert gas environments without metal contamination.
