HELLO ! look at here
They are easily oxidized at high temperatures and can only be used in neutral or reducing atmospheres except in vacuum.
Next, let's talk about the data of the product.

How much do you know about the characteristics of graphite rods?
1, Its coefficient of thermal expansion is small, its thermal conductivity is large, its resistance coefficient is (8~13)×10-6 Ω·m, its processability is better than that of SiC and MoSi2 rods, it is resistant to high temperatures, and has good resistance to extreme cold and extreme heat. The price Cheaper.
2,Graphite rods are often used as electric heating elements in high-temperature vacuum furnaces. The maximum operating temperature can reach 3000°C. They are easily oxidized at high temperatures and can only be used in neutral or reducing atmospheres except in vacuum.
3,The component is hard and brittle, has a small expansion coefficient, can withstand rapid cooling and heating, is not easily deformed, has good chemical stability, is extremely acid-resistant, does not react with strong acids, has poor alkali resistance, and can corrode the decomposition rod at high temperatures. body.
In what areas are graphite rods usually used?
1. Due to the high temperature of carbon rods, they are easy to conduct electricity and have good chemical stability.
2. It is now widely used in national defense, machinery, metallurgy, chemical industry, casting, non-ferrous alloys, light chemical and other fields. Especially black carbon rods are also used in ceramics, semiconductors, medicine, environmental protection, laboratory analysis and other fields, becoming The most widely used non-metallic material today.
3. When cutting steel, there is no need to use flammable and explosive gases like oxygen-acetylene flame cutting, which is low cost and safe to operate.
4. Arc cutting can be used to process a variety of metals that cannot be processed by gas cutting, such as cast iron, stainless steel, copper, aluminum, etc. It is highly efficient and can achieve ideal results.
