Graphite electrodes and crucibles are critical components in high-temperature industrial processes due to their exceptional thermal and electrical conductivity. Graphite electrodes are primarily used in electric arc furnaces to melt metals, particularly in steel production, where their ability to withstand extreme temperatures and conduct electrical current efficiently makes them invaluable. Similarly, graphite crucibles are designed to withstand high temperatures and corrosive environments, making them ideal for melting and casting metals and alloys. Both tools capitalize on graphite’s unique properties to enable precise control and efficient processing in various metallurgical and manufacturing applications.
Our high quality, strong and powerful Graphite Electrodes are used in various chemical and manufacturing industries, especially for electric arc furnaces in the production of steel.
We offer high quality Graphite Crucibles that can withstand high temperatures and are used in the melting of metals like gold, silver, copper and aluminium. It is used in the jewellery making and dentistry casting.
These graphite crucibles are resistant to thermal shocks and chemical erosion. We also offer these products at very competitive prices.
