Product Description

Graphite tubes are divided into medium-coarse graphite tubes and fine grain graphite tube according to different raw materials. In this chapter, we will focus on fine grain graphite tube.
Fine grain graphite tube, as the name implies, are graphite tubes with extremely high density and fine grain structure. Fine grain graphite tube have high thermal conductivity and chemical stability due to their unique structure, which is why they have become important components in aerospace, nuclear power, semiconductor manufacturing and other industries. In addition, the thermal shock resistance of graphite tubes makes them important in applications where temperatures change rapidly.

Graphite tubes are made of high-quality graphite material and are purified to a graphite content of 99.9% or above, making them ideal for use in extreme environments. Its characteristics are as follows:

1. High thermal conductivity, which allows them to effectively dissipate hot spot heat and maintain a stable temperature. This property makes them ideal for high temperature applications.

2. Low thermal expansion. This means they can withstand extreme temperature changes without cracking or warping, providing excellent dimensional stability under thermal cycling.

3. Conductivity. This makes it ideal for electrical discharge machining (EDM) applications. They also have excellent mechanical strength and hardness, which makes them wear-resistant and can be used in a variety of harsh environments.

4. High chemical stability, which makes them resistant to corrosion by various acids, alkalis and organic solvents.

In addition, high-purity graphite tubes are resistant to thermal shock, making them ideal for high-temperature processes involving severe temperature changes.
