Hafnium Carbide

Hafnium Carbide (HfC) powder supplied by Hunan Huawei Jingcheng Material Technology is a gray metallic material with a NaCl‑type cubic crystal structure and a purity rating of 99%+ as stated in the listing. The compound exhibits the highest known melting point among single substances, approximately 3,900 °C, which makes it suitable for extreme‑temperature environments. Its electrical and thermal conductivity, combined with a very low thermal expansion coefficient, are valued in aerospace and cutting‑tool applications. The supplier notes that the material is traded under HS code 2849.90 in kilogram and metric‑ton quantities.

The powder’s high elasticity index and impact‑resistance performance are typical of advanced refractory ceramics used for hard‑alloy coatings and missile nozzle throat linings. Industry practice usually targets a particle‑size distribution between 1 µm and 10 µm and a bulk density around 12.7 g cm‑3, although the supplier does not provide exact figures. Compliance with ASTM or DIN standards is commonly required, and buyers normally request a certificate of analysis confirming purity and particle‑size data. Packaging for export is generally performed in steel drums sealed under inert gas to prevent oxidation during transport.

End users such as aerospace component manufacturers, precision machining firms and high‑temperature coating specialists purchase Hafnium Carbide for its superior hardness and wear resistance. The material is often sourced in bulk, with shipments arranged under standard incoterms after the buyer confirms packaging, MOQ and lead‑time directly with the supplier. Because the listing does not disclose minimum order quantities or delivery schedules, interested importers should request those details before placing an order. Verification of the supplied certificates and alignment with local import regulations are essential steps in the procurement process.

Hunan Huawei Jingcheng Material Technology is based in Changsha, Hunan Province, China, as indicated by the listed address (Room 516, Hunan International Business Center, 410001). The supplier carries a “harbor” trust tier, which reflects a moderate level of verification on the marketplace platform. Its product catalogue includes high‑purity Hafnium Carbide powder for specialised industrial uses, and the company’s profile does not mention additional product lines or certifications.

The response metrics show a 0.00 % response rate and no recorded response time, suggesting that recent inquiries have not been answered through the platform. Prospective buyers should therefore confirm the supplier’s current contact details and communication readiness via alternative channels such as direct email or phone. Requesting recent business licences, tax registration and a sample certificate of analysis can help validate the supplier’s operational status before committing to a purchase.
