Graphite Statistics and Information

Graphite is a soft, crystalline form of carbon. Other forms are diamond and fullerenes (buckyballs). It is gray to black, opaque, and has a metallic luster. It is flexible but not elastic. Graphite occurs naturally in metamorphic rocks such as marble, schist, and

Die discharge machining, copper electrode and

The graphite material has a lower density than copper, and the same volume of graphite electrode weighs only 1/5 of the copper electrode. It can be seen that the larger volume of the electrode is very suitable for the use of graphite material, which greatly reduces the load on

Laser

Diamond is known as a promising electrode material in the fields of cell stimulation, energy storage (e.g., supercapacitors), (bio)sensing, catalysis, etc. However, engineering its surface and electrochemical properties often requires costly and complex procedures with addition of foreign material (e.g., carbon nanotube or polymer) scaffolds or cleanroom processing. In this work, we

Submerged arc welding

Submerged arc welding (SAW) is a common arc welding process. The first SAW patent was taken out in 1935. The process requires a continuously fed consumable solid or tubular (metal cored) electrode.[1] The molten weld and the arc zone are protected from atmospheric contamination by being submerged under a blanket of granular fusible flux
