Advantages of Tungsten Carbide Blank Solid Rods for milling

One of the most remarkable properties of carbide blanks solid bars for milling is their high hardness. This high hardness is mainly due to the hard phases in the alloy, such as tungsten carbide (WC). The bars also have excellent thermal hardness. During milling operations, a large amount of frictional heat is generated between the tool and the workpiece. Cemented carbide blank solid bars are able to maintain their hardness and cutting properties at higher temperatures.

It also has a certain degree of strength and toughness. This is due to the fact that in addition to the hard phase, there is also a bonding phase (e.g., metals such as cobalt) in the alloy. The bonding phase binds the hard phase particles together so that the bar will not break easily when subjected to the cutting and impact forces of the milling process.

The hardness of tungsten carbide blanks solid rods for milling is usually measured using Rockwell hardness (HRA). Its hardness range is typically between 89 - 94HRA. This hardness range makes it effective for a variety of milling tasks. For example, carbide rods with a hardness of 89 - 91HRA give good cutting performance when milling plain carbon and alloy steels, whereas for harder materials, such as hardened steels, carbide, etc., rods with a hardness of 92 - 94HRA are required.
