uhp 450 electrode graphite

Do you know the reason why copper was replaced by graphite as the material of uhp 450 electrode graphite?

In the 1960s, copper was widely used as a material for uhp 450 electrode graphite, accounting for about 90% of the total consumption, and graphite accounted for about 10% of the total consumption. In the current era, most users choose graphite as the main material of uhp 450 electrode graphite.

In Europe, 90% of uhp 450 electrode graphite has been made of graphite. Copper used to be the main material of uhp 450 electrode graphite. Compared with uhp 450 electrode graphite, the advantages of copper have almost disappeared. So what are the advantages of uhp 450 electrode graphite?

First, the processing speed is fast. Generally, the processing speed of graphite is twice that of copper, and the processing speed of electrical discharge is twice that of copper.

The second is that the material is not easily deformed.

The third is light weight. The density of graphite is only 1/5 of that of copper. The use of electrical discharge to process large uhp 450 electrode graphite can effectively reduce the load on the machine tool and is more suitable for large mold applications.

Fourth, the discharge consumption is small. Because the spark oil also contains C atoms, the high temperature causes the C atoms in the spark oil to decompose, and a protective film is formed on the surface of the uhp 450 electrode graphite to compensate for the loss of the uhp 450 electrode graphite.

Fifth, no burrs. After processing the copper uhp 450 electrode graphite, it needs to be manually trimmed to remove burrs, while the graphite processing is free of burrs, which saves a lot of cost and is easier to realize automated production.

Sixth, graphite is easier to grind and polish, because the cutting resistance of graphite is only 1/5 of copper, so it is easier to grind and polish by hand.

Seven points are low material costs and stable prices. Due to the increase in copper prices in recent years, the price of isotropic graphite is lower than that of copper, and the price of general graphite products is also lower and stable than the price of the same amount of copper.
