Import Graphite Block — Buy in Bulk from Supplier in China

Graphite blocks from Annie Huang are engineered for industrial applications requiring thermal stability and electrical conductivity. The material maintains structural integrity at temperatures exceeding 3000°C in inert environments, with typical thermal conductivity ranging from 100 to 200 W/m·K depending on grain orientation and purity. Machined blocks are available in custom dimensions, with standard tolerances of ±0.5 mm for precision components used in furnaces or EDM electrodes.

Annie Huang’s graphite is sourced from natural flake graphite, processed to achieve a carbon content of 99.5% minimum for standard industrial grades. Typical ash content remains below 0.5%, and density varies between 1.6 and 1.9 g/cm³ depending on the grade and compaction method. The material’s self-lubricating properties reduce friction coefficients to below 0.1 in dry conditions, making it suitable for sliding bearings and high-temperature seals.

These blocks are widely used in metallurgy for crucibles and molds, in semiconductors for heat sinks, and in chemical processing for corrosion-resistant linings. Buyers typically source in bulk with MOQs negotiated per project, while machining to final geometry is often handled post-delivery. Common packaging includes wooden crates or palletized boxes to prevent edge chipping during transit.

Annie Huang operates from Qingdao, Shandong, China, with an address at 308 National Road in the 266041 postal district. The supplier is classified as an imported-tier seller with a harbor trust tier, indicating established logistics capabilities for export shipments.

The supplier profile does not state response rate, average response time, or specific certifications, and no additional details about production capacity, client base, or years in operation are provided. Buyers should confirm verification status and export documentation directly with Annie Huang before finalizing orders.
