Graphite electrode rods are made of high purity, high density, high hardness and fine particle graphite. Its characteristics are heat resistance, thermal conductivity, resistance, good lubricity, and it is not easy to change its properties when melted. Due to good thermal conductivity, melting time can be shortened and energy consumption reduced. Long service life, as a graphite stirring rod, our crucible stirring rod has a much higher melting point and strength than other crucible stirring rods. Wide Application: Perfect for metallurgical industry, jewelry making and recycling industry. These graphite rod stirrers are Perfect for stirring in molten metals such as smelting casting refining gold silver and copper. It still stirs molten aluminum very well. These graphite crucible stirring rods have good thermal conductivity. For your , tie the graphite stirring rod with a wooden stick to add length, and wear professional heavy-duty crucible gloves to prevent while melting. Additionally, we recommend preheating the graphite rod to approximately 500F and holding it there for approximately 5 minutes before melting. size: about 30 x 0.8cm Material: graphite colour: Black Package Contents: 5 x Graphite Stir Rod Only the above package content, other products are not included.
