Product Features of EDM Graphite

In the current industrial field, with the development of economy and technology, the technical requirements for precision molds are getting higher and higher, so EDM is the focus of EDM in the processing of these precision molds. Therefore, it has received high attention from the industry in the screening of EDM materials.

In the past, most of the electrode materials were selected, such as electrolytic copper, copper tungsten, silver tungsten, etc. Of course, conventional graphite is also a good choice. So why did graphite not be the material of choice for EDM in the early years? That's because most graphite manufacturers have a combination of cost, quality, and work efficiency. Most of them use electrolytic copper as the preferred raw material for electric spark. In recent years, with the development of China's industry. In terms of technology, it has also achieved another world-famous achievement. In the field of precision mold industry, higher quality and lower cost have become the theme of the times. Therefore, it is a new wind vane to find newer graphite materials instead of copper electrodes in the industry.

Product Features Attribute Application Flow Chart
Stable and reasonable price
The price of graphite material requires only 15% of the equivalent volume of copper electrode. At present, graphite has become a popular material for EDM applications, and graphite materials are lower in cost and more stable.
Cutting is easier
Graphite has excellent machinability. The graphite electrode at the machining speed is 2-3 times more than the copper electrode. At the same time, graphite processing does not need to worry about burrs.
Low coefficient of thermal expansion
The melting point of copper is 1080 ° C, while the graphite of 3650 ° C graphite has a CTE of only 1/30 of copper. It is very stable even in the case of ultra high temperatures. Even in the processing of platinum electrodes, graphite electrodes have obvious advantages.
Light weight and low density
The density of graphite is usually 1.7-1.9 g/cm3 (copper is 4-5 times that of graphite). Compared to copper electrodes, graphite electrodes will reduce mechanical loading during this process. It is more suitable for large molds.
Good cutting
The volume of graphite is designed to be low compared to metallic materials. It has excellent machinability.
Super bonding effect
Crushed graphite can be bonded by an adhesive, which saves time and material costs.
Excellent resistivity
The resistivity (ER) determines the resistance of the material flowing to the current. Lower resistivity, which means better conductivity.

High-purity graphite molding also has excellent properties such as EDM applications:
Uniform particle size, high folding resistance, high hardness, corrosion resistance
