Product Description As a new kind of hi-tech product and the most rigid industrial material in the world, super abrasives is widely used in the field of metallurgy, oil drilling, mechanical process, instrument, electronics and modern top sciences. It's related closely to the development of industry, so synthetic diamond is praised as 'Treasure of industry'. It's rather popular among the users because of its good physical performance, like high strength, wear resistance and good thermal stability. We have excellent devices, complete testing methods and powerful technology force. Our diamond products are divided into three series (single crystalline diamond and diamond crush materials and diamond micro-powder). All the materialshave stable quality, complete specifications and can meet all kinds of requirement from users. Big size diamond series is 2mm to 7mm large diamond particles, the product can replace natural diamond, used in finish machining of high technology,etc. Diamond monocrystalline refers to the size of 20/30-70/80 high grade coarse particle synthetic diamond products. TTI/TI,shape, color, transparency reaches advanced standards in china, widely used for diamond saw cutting fields. Synthetic crush diamond is 100/120-500/600 granularity of medium and high grade synthetic diamond products.widely used for all kinds od griding wheels and tools with higher requirements on sharpness and strength. Synthetic diamond powder series are widely used in polishing, grinding, and lapping fields. You might be interested in other products,Please click on the image links.

FAQ FAQs: MASTERSIZER2000: The report of size distribution:the maximum value d(0.1) and minimum value d(0.9) determine size range. The peak value d(0.5) represents the highest concentrated size distribution. Impact strength tester Impact strength testing is an ASTM standard method of determining the impact resistance of materials. An arm held at a specific height (constant potential energy) is released. The arm hits the sample and breaks it. From the energy absorbed by the sample, its impact energy is determined. A notched sample is generally usedto determine impact energy and notch friability.(American Society for Testing and Materials,ASTM) TI/TTI value tester: Thermal Toughness Index, used to characterize the properties of diamond, its value size indicates the level of thermal stability. Dynamic Equilibrium Tester: This test is to determine the stability of the diamond. Q: What is Ti and TTi? A: Ti and TTi stand for Toughness Index and Thermal Toughness Index. This is a measurement of the impact strength of the superabrasive and its ability to resist mechanical breakdown (friability). The Ti test is performed on a superabrasive at room temperature. The TTi test is run at room temperature on a superabrasive previously raised to an elevated temperature and allowed to cool down – this mimics the performance of the superabrasive in a grinding wheel in “real world” conditions. The Ti and TTi test is performed to ANSI (American National Standards Institute). Q. Is there a minimum order quantity? A. No, you may order as few pieces as you wish. Q. What is the delivery time? A.Generally, your goods will be delivered within 3days after the confirmed order. If for some reason your order cannot be fulfilled you will be advised by e-mail. Q: In a Particle Size Distribution (PSD) curve, what do the terms Median, Mode and Mean represent? A: Median: the size where 50% of the particles is below/above that size Mode: the size with the highest frequency (i.e. the greatest number of particles with the largest size) Mean: the average size of the entire particle population Q: What is a SUPERABRASIVE? A: A very hard abrasive, usually natural or synthetic diamond and cubic boron nitride (CBN). Hardness is measured on the Knoop Scale in megapascals (1 Mpa = 145 lb / in2 ) and diamond is 7000 Mpa with CBN following at 5000. Conventional abrasives such as silicon carbide and aluminum oxide have much lower Knoop values of 2500 and 2200 respectively. Q: What are the key properties of superabrasive particles? A: Size, shape, color, surface (extrinsic) chemistry, internal (intrinsic) chemistry, mechanical properties -- Ti and TTi (toughness index / impact strength and thermal toughness index), zeta potential (surface charge) and microstructure. Q: What is friability? A: A measure of the ability of a superabrasive to be pulverized, crumbled or otherwise reduced to a powder. Ti and TTi testing are employed to measure friability in superabrasives. Q: What is Particle Size Distribution (PSD)? A: Most individual grains of a superabrasive powder batch are not the same size (or shape). The powder consists of a distribution of particles of different sizes represented as afrequency distribution curve. HengFeng provide the best service to diamond buyers
