Frequently Asked Questions

What types of graphite do you manufacture?

We produce a wide range of graphite materials including EDM Graphite, Silicon Graphite, Lithium Battery Graphite, Casting Graphite, Semiconductor Graphite, Fuel Cell Graphite, Sintering Graphite, Crucibles Graphite, Carbon Brush Graphite, Graphite Welding Blocks, and Copper Graphite.

Are your products suitable for high-temperature applications?

Yes, our graphite materials are engineered for high thermal stability and resistance to thermal shock, making them ideal for crucibles, heaters, sintering, and continuous casting processes.

Can you customize graphite blocks to specific dimensions?

Absolutely. We offer custom machining and sizing for graphite blocks, rods, and components to meet your exact technical specifications.

What is the difference between isostatic and extruded graphite?

Isostatic graphite is pressed uniformly from all directions, resulting in isotropic properties and fine grain structure, ideal for precision applications. Extruded graphite is formed through a die, offering good mechanical strength and cost efficiency for larger blocks.

Do you provide technical data sheets?

Yes, detailed technical specifications, including bulk density, compressive strength, flexural strength, grain size, and purity, are available for all products upon request.
