Cylindrical Graphite Electrodes
Graphite electrodes are used across a range of industries as a conductor in applications like electroplating and electrolysis. Their cylindrical shape and smooth surface make them especially effective and durable when it comes to transferring electricity. Here, we will discuss the nominal dimensions of cylindrical graphite electrodes, their advantages, and applications.
Cylindrical graphite electrodes are mainly produced in five sizes: 8, 10, 12, 14, and 16 inches, though larger and smaller sizes can also be created if needed. The diameter of the cylinder is known as the nominal diameter, which is determined by the electrode’s size. Therefore, 8 inch electrodes have a nominal diameter of 0.625”, 10 inch electrodes have a nominal diameter of 0.750”, 12 inch electrodes have a nominal diameter of 0.875”, 14 inch electrodes have a nominal diameter of 1”, and 16 inch electrodes have a nominal diameter of 1.125”. The depth or length of the cylinder is also determined by the diameter and can vary between 2.5 to 3.5 times the nominal diameter.
Cylindrical graphite electrodes have several advantages over other options like copper and aluminum. These include their high electrical conductivity, low thermal expansion, low thermal contact resistance, and low temperature coefficient of electrical resistance. Additionally, graphite electrodes are lightweight, strong, and resistant to abrasion, making them a suitable option for high-load applications.
Due to their versatile design, cylindrical graphite electrodes can be used in a variety of different applications. They are most commonly used in electroplating, electrolysis, welding, refractory lining, and more. Additionally, graphite electrodes are the ideal option for non-aqueous electrolyte applications, due to their high compatibility with solvents.
In conclusion, cylindrical graphite electrodes are an optimal choice for a variety of applications, due to their impressive electrical conductivity and abrasion-resistant properties. Because of their unique shape, they are also capable of transferring electricity without the risk of overheating or damage. When selecting a cylindrical graphite electrode, it’s important to be aware of its nominal diameter, as this will determine its depth or length. This will allow you to make sure that the electrode meets your requirements and is the right size for your application.
