Graphite Electrode Material Choose

As is known to all, graphite has the quality characteristics that cannot be replaced by other metal materials. Graphite electrode materials in the actual selection of materials often have a lot of people feel trivial characteristics. There are many reasons to choose graphite materials, but there are four main criteria, which we will describe in detail below.

For materials with the same average particle size and low resistivity, the strength and hardness of graphite electrode materials will be slightly lower than those with high resistivity. Discharge rate, loss will also be different. Therefore, the natural resistivity of graphite material is very important in practical application. The choice of electrode material is directly related to the discharge effect. To a large extent, the selection of material is appropriate, which determines the discharge speed, machining accuracy and surface roughness.

In the special graphite industry, the common hardness test standard is the xiao hardness measurement method. It tests on a different principle from the raw materials used in metals, although in our unconscious understanding of graphite, it is generally considered to be a softer material. However, the actual test data and applications show that the hardness of graphite is much higher than that of metal materials. In addition, because of the layered structure of graphite, it has a very superior cutting function in the cutting process, and the surface is easy to handle after machining.

The bending strength of graphite electrode materials is the direct reflection of material strength. It can directly show the tightness of the internal structure of the material. High strength graphite material, its discharge loss resistance performance is relatively good, for the high precision of the electrode, we should try to choose the material with good strength.
