Graphite Rod

Graphite Rod manufacturer and supplier

Graphite Rod

Graphite rods are machined from graphite electrodes to specific dimensions. Because graphite is corrosion resistant, its rods retain their structure even after thermal shock and exposure to temperatures up to 5000°F. Pure graphite particles are used to make graphite rods. The most common methods of manufacturing it are extrusion, compression, molding, and pressing. It is also ideal for the fiber optic industry as it is made from the non-reactive material graphite.

What is a Graphite Rod?

Graphite rods are solid cylindrical rods machined from artificial graphite. They have the properties of graphite, namely excellent electrical conductivity, corrosion resistance, and wear resistance. Graphite rod electrodes come in various sizes and are commonly used in the mechanical and electronic industries.


It comes in various shapes and sizes, making them suitable for multiple applications. The most common types of graphite rods are standard round and hexagonal rods. Traditional round rods are the most common type used in various applications due to their strength and versatility. Hexagonal rods are also popular and often used in applications requiring accuracy and precision. Special graphite rods are also available for turbocharging and high-performance engines.graphite rod for electrictygraphite rod spec
