Graphite is a versatile material known for its unique mechanical properties.
10 Key Points to Know About the Mechanical Properties of Graphite
1. Compressive Strength
- Compressive strength is the ability of graphite to withstand a crushing force without breaking or deforming.
- The minimum value of compressive strength for graphite is 31 MPa (SI units).
- The maximum value is 50.038 MPa (imperial units).
2. Ductility
- Ductility measures the ability of a material to deform under tensile stress, allowing it to be stretched or drawn into a wire.
- The minimum value of ductility for graphite is 0.00171 (SI units).
- The maximum value is 0.00189 (imperial units).
3. Elastic Limit
- Elastic limit refers to the maximum stress that a material can withstand without permanent deformation.
- The minimum value of elastic limit for graphite is 4.8 (SI units).
- The maximum value is 11.0229 (imperial units).
4. Endurance Limit
- Endurance limit represents the maximum stress amplitude that a material can withstand for an infinite number of cycles without failure.
- The minimum value of endurance limit for graphite is 15.47 (SI units).
- The maximum value is 2.61793 (imperial units).
5. Thermal and Chemical Resistance
- Graphite has extremely high thermal and chemical resistance.
- It also has excellent thermal shock resistance.
6. Electrical and Thermal Conductivity
- Graphite has high electrical and thermal conductivity.
- Its strength increases with rising temperature.
7. Ease of Machining
- Graphite is easy to machine.
- It can be produced with high purity.
8. Industrial Applications
- Graphite is widely used in various industries such as nuclear, metallurgical, semiconductor, solar, continuous casting, and EDM.
- It is commonly used as a die material in hot pressing equipment due to its low density, thermal stability, and mechanical strength.
9. Limitations
- Graphite has limitations in terms of high pressure applications.
- It can react with certain materials like transition metals, nitrides, and silicides from transition metals.
10. Thermal Shock Resistance and Chemical Inertness
- Graphite tubes become stronger when heated from room temperature to 2000 °C.
- They have exceptional thermal shock resistance and are chemically inert, making them suitable for applications where corrosion is a concern.
