Graphite Applications and Industries
The demand from the industry over the years has been for carbon with increasingly tighter and stable properties of it. In this context, Expo plays an important role in India for providing solutions in Isostatic Graphite. Our excellence is recognized by our customers, with whom we grow together. Our isotropic graphite products are used across a wide field of industries.
- The semiconductor industry, where innovation is rapidly advancing
- The environmentally friendly renewable energy industry
- The mold industry, where accuracy is such a priority
- The atomic power industry, where trust and reliability is avital factor
Features of Isostatic Graphite -
1. High Reliability
Isotropic graphite is stronger than conventional graphite due to its micro particle structure. This produces a highly reliable material with a small characteristic variation.
2. Ultra Heat Resistance
In an inert atmosphere, stable use is possible even in extremely high temperatures of 2,000°C or more. The material has low thermal expansion and a high coefficient of thermal conductivity, giving it excellent thermal shock resistance and heat distribution properties, with low thermal deformation. It also has a special characteristic whereby its strength increases as the atmospheric temperature gets higher up until 2,500°C.
3. Excellent Electrical Conductivity
The high and excellent heat resistance mean graphite is the optimum material for applications such as high temperature heaters.
4. Excellent Chemical Resistance
With the exception of some strong oxidizers, it is chemically stable. Graphite can be used stably even in environments that cause some metals to corrode.
5. Lightweight and Easy to Machine
The bulk density is low as compared with metallic materials- enabling a lightweight design. In addition, it has excellent mechanical machining properties-facilitating accurate shaping.
Applications of Isostatic Graphite in various Industries -
Expo’s graphite products are highly regarded for their excellent performance and reliability and are used across a wide range of fields that are essential in our everyday lives.
