Is the hard alloy the same as the cemented carbide?
Is essentially the same, are two kinds of powder alloy materials, but the composition is different, its processing performance depends on the alloy material of concrete, in my experience, super hard alloy toughness than hard alloy with high hardness, but lower than the hard alloy, don't be misled by the literal meaning, the word super tool hard alloy generally refers to add the other ingredients of high speed steel the hardness wear resistance than ordinary high speed steel (of course not hard alloy) without losing the advantages of high speed steel toughness.
Dissimilarity！Cemented carbide refers to one or more refractory metal carbides (WC, TiC, etc.) as hard phases, and transition metals (Co, etc.) as bonding phases and multiphase materials prepared by powder metallurgy technology. As carbide tools for cutting tools, the commonly used carbides are WC, TiC, TaC, NbC and so on. The commonly used bonding phases are Co, Ni, Fe and so on. The strength of cemented carbide depends mainly on the content of the binder phase.The ultra-fine Grain Cemented Carbide Kennametal company launched a new brand KC5525, KC5510 uses the high cobalt hard alloy matrix grain refinement, cemented carbide substrate with super grain refinement cobalt content up to 10%, with TiAlNPVD coating with high aluminum content, the tools in intermittent cutting with high edge toughness at the same time, also has a very strong deformation resistance. ISCAR company for solid carbide end mills "AL-TEC" brand series of coating, with ultra-fine Grain Cemented Carbide with high aluminum content, TiAlN (PVD) coating, which in milling high hardness of 60 ~ 62HRC hardened steel, compared with the original IC903 grade, improve tool life 150%. Valenite company for cast iron in high-speed turning VP1595 grades, but also in the ultra-fine grain cemented carbide substrate, using MT-CVD coated with 18 m thick TiCN/Al2O3/TiC coating, the flank is coated with a layer of gray TiC, in order to facilitate and blade rotation observing the wear of cutting edge, the grade in rough machining ductile iron, the processing efficiency than other K05 ~ K10 grade increased by 50%.
Superhard alloy and cemented carbide are not the same ah.Personally, the alloy feels like a metal of high hardness; for this is not very familiar, there is no right to speak;But the main component of cemented carbide is WC+Co. And some have TIC.TaC. Equal carbide. Basically out of the metal range.So you say cemented carbide and hard metal are different.If it is replaced by superhard materials and cemented carbide to compare. The carbide can be cemented into the superhard material.These are personal views and can be discussed more
The CBN price is a little high. If you can't accept it, you can consider using the ceramic cutter to test the PCBN (CBN) blade. Ceramic blades can not work (he is brittle, easy to crack), super hard tool sales
