Extruded graphite and isostatic graphite are two different types of graphite that are produced using different manufacturing processes and have distinct properties.
Extruded graphite is produced through an extrusion process, where the raw graphite material is forced through a die to create the desired shape. This process results in a coarser grain size and lower strength compared to isostatic graphite. However, extruded graphite has higher thermal and electrical conductivity.
On the other hand, isostatic graphite is produced using a cold isostatic pressing (CIP) method. In this process, the raw material mixture is compressed into rectangular or round blocks using a cold isostatic press. Isostatic graphite is known for its ultra-fine grain size and excellent mechanical properties.
The main difference between extruded and isostatic graphite lies in their grain size and strength. Extruded graphite has a coarser grain size and lower strength, while isostatic graphite has a much finer grain size and higher strength. This makes isostatic graphite more suitable for applications where high mechanical properties are required.
Additionally, isostatic graphite exhibits superior resistance to thermal shock, high temperature and oxidation resistance, low electrical resistance, good corrosion resistance, and precise machining capabilities. It also has a low content of impurities and can be produced with very high purity.
Extruded graphite, on the other hand, is preferred for applications that require high thermal and electrical conductivity, such as in electrical components or thermal management systems.
In summary, the difference between extruded and isostatic graphite lies in their manufacturing processes, grain size, and resulting properties. Extruded graphite has a coarser grain size, lower strength, and higher thermal and electrical conductivity, while isostatic graphite has a finer grain size, higher strength, and superior mechanical properties.
