Graphite electrode rods are made of high purity, high density, high hardness, and fine particle graphite. These rods exhibit excellent heat resistance, thermal conductivity, electrical resistance, and good lubricity, and they maintain their properties under high-temperature conditions. Due to their superior thermal conductivity, they help reduce melting time and energy consumption. Long service life: As a graphite stirring rod, this crucible stirring rod offers a higher melting point and greater strength compared to other stirring rods. Wide application: Ideal for use in the metallurgical industry, jewelry making, and recycling industry. These graphite stirring rods are suitable for stirring molten metals such as gold, silver, copper, and aluminum during smelting, casting, and refining processes. These graphite crucible stirring rods feature excellent thermal conductivity. For safe handling, attach the graphite stirring rod to a wooden stick to extend its length and wear professional heavy-duty crucible gloves during use. It is recommended to preheat the graphite rod to approximately 500°F and hold it at that temperature for about 5 minutes before use.
