Import Diamond And Carbon Film Material — Buy in Bulk from Supplier in China

Diamond and carbon film material from Zhengzhou More Superhard Company consists of nano-grade diamond, industrial-grade diamond, and polycrystalline diamond coatings deposited on substrates using chemical vapor deposition or physical vapor deposition methods. The base materials include high-purity graphite, iron catalysts, and pyrophyllite synthesis blocks, with crystal seeds enabling controlled diamond growth. These films are not bulk diamond but thin, adherent layers engineered for surface modification.

Typical film thickness ranges from 0.1 to 10 micrometers, with hardness values exceeding 80 GPa on Vickers scales. The carbon content is predominantly sp3-bonded diamond, with sp2 graphite phases present in lower concentrations depending on deposition parameters. Standard substrate materials include tungsten carbide, silicon, and stainless steel. These films are not jewelry-grade but designed for industrial wear resistance and thermal conductivity enhancement.

End users include manufacturers of cutting tools, drill bits, and wear-resistant components in automotive, aerospace, and precision machining industries. Buyers typically require coatings with low surface roughness, high adhesion strength, and thermal stability up to 600°C. Packaging is in sealed anti-static containers with desiccant. Trade terms are FOB Zhengzhou, with MOQs negotiated per batch size and coating type.

Zhengzhou More Superhard Company operates from No.171 Zhongyuan Road in Zhengzhou, China, with a focus on synthetic diamond materials and carbon-based thin films. The company is registered as a manufacturer and does not claim certifications such as ISO or CE. Its trust tier is harbor, indicating basic supplier verification, but no response rate or lead time data is provided in the listing.

The supplier does not disclose annual production volume, employee count, or client names. It sources raw materials including high-purity graphite and iron catalysts locally and processes them into diamond films using proprietary deposition systems. The product range includes coatings for tools and industrial components, not finished products. Buyers should verify coating performance through sample testing before bulk orders.
