Characteristics of GG25

GG25 is a type of cast iron and represents a material standard generally used in Europe. Some typical features of GG25 are:

  1. Chemical Composition : The chemical composition of GG25 cast iron generally includes about 3.5% carbon, 2% silicon, 0.5% manganese, 0.3% phosphorus and 0.1% sulfur. These are typical values ​​and may vary depending on the production process and standards.
  2. Strength Properties : GG25 cast iron generally has a certain compressive strength and tensile strength. Strength properties may vary depending on factors such as casting conditions and cooling rate.
  3. Density : The density of GG25 cast iron is generally between 7.0-7.3 g/cm³. Density is important for the compactness and structural strength of the material.
  4. Thermal Properties : Properties of GG25, such as coefficient of thermal expansion, thermal conductivity and thermal stability, determine the behavior of the material at different temperatures and thermal conditions.
  5. Machinability : GG25 cast iron can be machined and shaped after casting. However, thermal treatments before and after processing can affect the properties of the material.

GG25 cast iron is often used in industrial applications, machine parts, pipe fittings, valve bodies and many other areas. It is preferred due to its durability, wear resistance and workability. However, usage characteristics and performance may vary depending on specific application and industry requirements.
