What are the materials of wire cutting conductive blocks?
We all use wire cutting conductive blocks in WEDM processing, so do you really understand wire cutting conductive blocks? Do you know what the materials of wire cutting conductive blocks are? Below, KENOS gives you a detailed analysis.
In fact, the wire cutting conductive blocks we generally use are made of cemented carbides, and we can divide them into four main categories depending on the addition of other carbides:
1.Tungsten Cobalt (WC Co) cemented Carbide (YG)
It is composed of WC and Co. It has high flexural strength and good thermal conductivity, but its heat resistance and wear resistance are poor. It is mainly used to process cast iron and non-ferrous metals.
2.Tungsten Titanium Cobalt (WC TiC Co) cemented Carbide (YT)
Because the hardness and melting point of TiC are higher than that of WC, compared with YG, the hardness, wear resistance, red hardness of TiC are increased, the bonding temperature is high, the oxidation resistance is strong, and TiO _ 2 is formed at high temperature, which can reduce the bond. But the thermal conductivity is poor, the bending strength is low, so it is suitable for processing steel and other toughness materials.
3.Tungsten, Tantalum and Cobalt (WC TaC Co) cemented Carbide (YA)
On the basis of YG cemented carbides, the addition of TaC (NbC), improves the hardness and strength at room temperature, high temperature, thermal impact resistance and wear resistance, and can be used in the processing of cast iron and stainless steel.
4.Tungsten, Titanium, Tantalum and Cobalt (WC TiC TaC Co) cemented Carbide (YW)
On the basis of YT cemented carbides, the addition of TaC (NbC), improves the bending strength, impact toughness, high temperature hardness, oxygen resistance and wear resistance. Not only can process steel, but also processing cast iron and non-ferrous metals. Therefore, it is often called universal cemented carbide (also known as universal cemented carbide). At present, mainly used for processing heat-resistant steel, high-manganese steel, stainless steel and other difficult-processing materials.

The above is the four big material classification of the wire cutting conductive blocks, which is helpful for you to purchase the conductive block. At the same time, grasp the main causes of wear and tear of the WEDM conductive blocks in processing will help you to better process.
