Oil field wear parts.Things to Consider When Selecting a Tungsten Carbide Grain size Smaller grains give better wear and larger grains give better impact resistance. Very fine grain tungsten carbides give very high hardness while extra coarse grains are best in extremely severe wear and impact applications such as rock drilling and mining applications. More cobalt generally makes a tungsten carbide harder to break
Binder content, hardness or grain size. In straight matrix materials any two of these will match the third. A 15% binder with hardness of 88.0 RA would have to be fine grain material whereas with a hardness of 86.0 RA would need a very coarse grade to achieve it. Specifying cobalt binder only Tungsten Carbide Grade Products & Suppliers Description carbides, from very fine grades with an average grain size of approx. 0.5 µm to very large average grain sizes of approx. 50 µm. Moreover, nanocrystalline tungsten carbides are being tested in new applications and for increasing hardness.

To control uniform grain size, wet milling is the first step. Extrusion. Before extrusion, it shoud be dried and granulated. Extrusion is the main way to press long carbide rods like 300, 310,330mm. We manage diffrent diameter carbide rods with different extrusion machine to micron fine grain tungsten ringsUnderstanding Carbide Substrates used in End Mills micron fine grain tungsten ringsIn general, smaller tungsten carbide grain sizes allow for the manufacture of carbides with a finer microstructure. A prerequisite for this is the prevention of grain growth during the sintering process by adding suitable doping (process of adding some impurity atoms) components in the right amount, adjusted to the cobalt content.
