SF Diamond (SFD for short) is a high-tech enterprise that specializes in the manufacture of Polycrystalline Diamond (PCD) and related products. SF Diamond was founded in 1997 in the city of Zhengzhou, the capital of Henan province, in the heartland of China. SFD is devoted to satisfying customers with premium quality products and customized service. Relying on its strong R&D team, SFD has developed a reputation for excellent performance, consistency, competitive prices and timely delivery, and become a leading manufacturer of PCD and composite superhard materials.
SF Diamond's PCD products are produced by advanced high temperature and ultra-high pressure technology. Specially selected diamond powders are sintered together in the presence of a catalyst metal such that strong diamond-to-diamond bonding occurs. This forms hard, abrasion resistant blanks that have the high thermal conductivity of natural diamond with a toughness approaching that of tungsten carbide.
SF Diamond has large and modern production facilities. The company has a complete range of products and the most advanced technology. SFD products are widely used in oil & gas drilling, coal and other mining, machining, building materials, automobile, railroad and other industries. The majority of SFD production is exported to more than 40 countries worldwide.
SF Diamond has the largest composite super-hard material R&D and manufacturing facility in China.
SF Diamonds' people continually pursue providing the highest quality products, ever improving performance and superior service to our customers.
