The 2nd China (Zhengzhou) International Abrasives Grinding Exhibition was successfully held at the Zhengzhou International Convention and Exhibition Center from November 15th to 17th. Shandong Changrun Diamond Co., Ltd. exhibited and displayed many super-hard materials and products, which attracted many visitors. China Superhard Materials Network reporter visited and visited Shandong Changrun Diamond Co., Ltd.


Shandong Changrun Diamond Co., Ltd. is a standardized joint-stock enterprise specializing in the R&D, production and sales of super-hard materials and products. The company's investment scale and product market competitiveness rank among the top in the domestic industry and it is one of the most influential synthetic diamond suppliers in the world.

The company's main products are grinding grade diamond, saw-cut grade diamond, large-diameter diamond single crystal, diamond micro-powder, diamond composite sheet, cubic boron nitride and so on. The product range is complete, in addition to the regular series and high-end products, it also provides customers with personalized product design services to meet the needs of customers. Strict quality control methods and advanced testing and inspection standards provide reliable guarantee for product quality, and product quality is at the international advanced level.

CRJ series:

Most of the crystal forms are regular six-octahedrons with good purity, high sharpness and excellent strength, good thermal stability and strong impact resistance.

The crystal is a complete six-octahedron with crystals full, regular shape, good purity, high strength, toughness, good thermal stability and strong impact resistance.

CRH series:

This product is a new type of super hard and ultra-fine abrasive. It is widely used in mechanical, electronic, aerospace and military fields. It is an ideal material for grinding and polishing hard materials such as hard alloys, ceramics, gemstones and optical glass.

Large grain diamond single crystal series:

The product has a large particle diameter, less internal impurities, less surface defects, and good crystal morphology.

Plating series:

Nickel-plated diamond can increase the holding power of the diamond and extend the life of the tool.

Titanium-plated diamond helps prevent diamond from being corroded by metal powder and improves tool life.

CRW series:

The raw material is made of high-strength, high-purity high-quality diamond. The crystal shape of the product is regular, the particle size distribution is extremely concentrated, the particle shape is close to spherical, the impurity content is extremely low, the thermal stability is good, and the wear resistance is high.

CBN series:

The product has different colors such as black, bright black and amber. It has good thermal stability and heat resistance up to 1400-1500 °C, which is almost twice as high as the heat resistance of diamond (700-800 °C). Suitable for processing all kinds of ferrous metals, its processing efficiency is hundreds of times that of ordinary tools. Can be widely used in aerospace, automotive, bearing, mechanical and electronic industries.

PCD series:

Diamond composite sheet for oil/natural gas and mine drill bit: This type of composite sheet is made by sintering at high temperature and high pressure by advanced sintering process. It has good wear resistance, self-sharpness and impact resistance, and is suitable for soft to Medium-hard geological rock formations are widely used in oil, gas drilling and mining drilling industries.

Diamond composite sheet for cutting tools: This type of composite sheet has excellent properties such as high hardness, good wear resistance and good impact toughness. Can be widely used in copper, aluminum and other non-ferrous metals and their alloy materials, wood, laminate flooring, graphite, rubber, plastics, ceramics, refractory materials and other processing areas, high processing efficiency, good surface finish of the workpiece, is to achieve the car grinding, Ideal composite superhard material for high efficiency and low cost machining.

Granular carbon processing in the pellet carbon basis is Huahui Company's second series of products. High hardness of pellet carbon can meet different users` demands of various effective particle size of irregular carbon and uniform coefficient.

The high adsorption carbons Granular activated carbon, which is the second main products following pellet carbon of HuaHui Company, can be produced in various distribution, the specification produced through the year includes HP-8X30 (8X30 mesh), HP-12X40,HP-5X7,HP-12X30,HP-20X40 and so on.

Granular Activated Carbon is the extension and supplement on products manufacturing and service of pellet series. This type of activated carbon is finished by machanical breaking and screening of pellet series, therefore, it has the pore characteristics of pellet activated carbon.
